Grand Mercure Nasu Kogen Review: A Night There With My 3-Year-Old

We stayed one night at Grand Mercure Nasu Kogen Resort & Spa — my wife, our 3-year-old daughter, and me. It's often introduced as a "resort popular with kids," so here's an honest account of what it was actually like, warts and all.

To give you the short version up front: having a play area and a bar inside the hotel, close enough to move between easily, mattered more than we expected — that's the impression that stuck with us most from this trip. Writing this as a couple in our 30s traveling by car with a 3-year-old during a snowy stretch of winter, I'll go into as much detail as I can about the property's internal layout, the food, the bath, and the surrounding area.

When we went, who was with us, and the weather on the day

First, the conditions, since your experience will look different depending on yours — I'll spell these out in detail so you can compare against your own family.

• Season: deep winter, with solid snowfall
• Length of stay: 1 night, 2 days
• Family: a couple in our 30s + our 3-year-old daughter
• Transportation: our own car (highway from the Kanto area)
• Weather: snowing the whole stay — the parking lot was solid white when we woke up
• Goal: not sightseeing, but a stay with a young child that's entirely self-contained within the hotel

Resort hotels in the Nasu Kogen area are mostly built around driving, and this one is no exception. Multiple YouTube reviews commonly mention that "it's a bit of a haul from the station if you're coming by train," and that matched what we'd read beforehand. Getting there from the station via local transport with a 3-year-old and a pile of luggage is honestly rough, so it's safest to assume this is a property that's convenient if you're driving, and one where train travelers should plan around a transfer.

Nasu in winter means snow and ice, so winter tires are non-negotiable. We drove up the highway from the Tokyo area, and the mountain road after the interchange had patches of white on the pavement — without 4WD plus winter tires, it might have been unnerving. With a kid in the car, don't cut corners on equipment — that's what I kept telling myself the whole drive up.

We've written separately about the general approach to choosing a family resort in our guide to picking a hotel, but for Grand Mercure Nasu specifically, whether we could turn winter snow into play turned out to be the single biggest factor in how satisfied we were. From here, I'll walk back through that experience in roughly chronological order.

From arrival to the room: sensible luggage storage and a decor that feels almost overseas

We arrived a little before check-in officially opened. As is typical with a young child, things rarely go according to our own schedule, so arriving early and just dropping off our luggage is our family's go-to move. Grand Mercure Nasu had this handled well — the path from the entrance to the front desk was wide, and walking through it with a stroller or holding our 3-year-old's hand never felt cramped.

What struck us the moment we arrived was how sensible the luggage storage was. Even before check-in, they took our bags with just a quick "may we get your name?" — and the classic family-travel headache of "where do we even put all this luggage?" never became a source of stress. That's a small thing, but it matters. The alternative — a 3-year-old demanding to be carried while the parents stand stranded holding a suitcase, a duffel bag, and a paper bag — simply didn't happen, and that alone set a better tone for the whole stay.

We spent the wait before check-in around the lobby. There were sofas to sit on, arranged so that even if our daughter wandered off a little, she never disappeared from our sightline. Whether or not a space like this exists makes a real difference to how worn out you are after the first hour of a trip with a 3-year-old.

• A wide path from the entrance to the front desk
• Smooth luggage storage before check-in
• Lobby seating arranged so a wandering child stays in view
• Enough space to take coats on and off (winter means more gear)

As is common at all-inclusive-style properties, they walked us through the lounge usage, the facilities, and the dinner reservation status all at once during check-in. There's a lot of information to absorb, so having a paper notebook or a note-taking app ready saves you trouble later. My wife handled the check-in briefing while I focused on keeping our daughter's "I want to go play already" in check. Division of labor matters. We've covered the basics of using an all-inclusive stay separately in our all-inclusive hotel guide, but how much you get out of the lounge as "a place to be" during your stay clearly shapes how satisfied you end up.

Our daughter's reaction the moment we entered the room, and the tone of the decor

We weren't in a special kids' room, just a standard room type. At booking, we hesitated over "is a regular room really fine at a kid-focused property?" — but in the end, it was the right call. The reason is simple: the room ended up being purely for sleeping, and nearly all our waking hours were spent in the hotel's play area and lounge. Even without kid-themed decor, the quality of the stay didn't suffer at all.

The moment we opened the door, the first thing our 3-year-old ran toward was the bed. A 3-year-old diving onto a hotel bed — a classic. A parent yelling "shoes! take your shoes off!" to stop her — also a classic. The burst of energy a kid gets the instant they step into a space that isn't home reminds you exactly why trips like this are worth it.

My wife and I both said, "huh, this feels almost like being overseas," about the tone of the decor. Grand Mercure is a brand run by Accor, the French hospitality group, and the interior sticks to clean, straight lines closer to an overseas resort hotel than to a traditional Japanese ryokan with tatami and shoji screens, and different from a typical city hotel too — it has more of a genuine "resort" feel. Getting an overseas-resort-style experience with kids in tow, all without leaving Japan, is a quietly effective source of satisfaction.

• The bed is spacious enough for a 3-year-old to dive onto with room for a parent too
• Snow scenery right outside the window gives an instant sense of "this is a special day"
• Clean, modern furniture arrangement with no sharp corners to worry about as a kid runs around
• A table and enough space to spread out your luggage

Something not to underestimate on a trip with a 3-year-old is the room's internal layout. Whether there's space to open a suitcase, lay out your child's clothes, and give a stuffed animal its own spot determines how messy things get during the stay. Grand Mercure Nasu's room held up well on this front — even at bedtime, once we'd dimmed the lights, there was still enough space left for us to work quietly afterward. We've put together a comparison of the concepts behind the three Grand Mercure "sibling" properties in our three-resort comparison article.

The biggest value: a play area and lounge inside the hotel

The thing that exceeded our expectations the most on this trip was having a play area inside the hotel. We'd known about it beforehand, but experiencing it firsthand made about three times the impression we expected.

Outside, it was snowing. At a typical property, "how do we keep the kid entertained" becomes the parents' problem — but here, it wasn't.

1. Walk a short distance from the room and you reach a spacious indoor play area
2. It has toy trains and toy horses, which kept our daughter occupied for ages
3. Right next to it, parents can have a coffee in the lounge, or a drink at the bar
4. Once she got bored, we'd head back to the room to rest — then back to the play area — then the lounge again
5. Before we knew it, evening had rolled around, and the time until dinner had melted away with zero stress

This cycle works better than we expected. Both a child's need to play and a parent's need to relax get satisfied on the same floor. We've stayed at all kinds of properties over the years, but this trip made it unmistakably clear that just having a play area right there completely changes the quality of a stay.

How the toys in the indoor play area were arranged, and how our daughter played

What worked well about the indoor play area's layout was that the toys were organized into distinct zones. A space for building train tracks, a space for playing with horse and animal figures, a picture book corner — the layout let a 3-year-old move on her own with a clear "I'm doing this next." What's tricky with young kids is the "what now?" moment once they get bored with one toy, so having the space split into zones lets the child choose for herself, which is a big deal.

Our daughter started off completely absorbed in building train tracks, focused on her own for about 20 minutes. My wife and I had coffee in the lounge meanwhile and genuinely said to each other, "this might be heaven." Having a spot where a 3-year-old focuses solo for 20 minutes is, on its own, enough to let parents actually rest.

After that, she moved on to the horse toys, started up a little one-person play with her stuffed animal in the conversation, and finished up lying on the floor in the picture book corner flipping through books. It's genuinely hard to build a space at home or at a park where a 3-year-old plays through that much variety in one spot, so having it inside the hotel is genuinely valuable. We've touched on how to spend a rainy or snowy day inside a hotel in our rainy-day hotel activities article, but Grand Mercure Nasu struck us as the kind of property that really shows its value precisely when the weather turns bad.

Drinks and snacks in the lounge, and how we spent our time

The all-inclusive lounge, used as a spot to stop by between meals for a light snack and a drink, matched our family's rhythm well. It felt less like "eat three full meals" and more like "there's somewhere to wander into all day long."

Drinks included coffee, tea, and soft drinks, plus alcohol depending on the time of day. I had a beer and a highball here and there, and my wife enjoyed a glass of wine. The snack side leaned toward light bites — nuts and simple finger food — not enough to fill you up on its own, but just right alongside a drink.

Having the bar nearby mattered a lot too, since the lounge-style setup let the "kid plays, parent has a drink, kid plays again" cycle run naturally. Our daughter played with total focus, and we could watch over her with a drink in hand. With that loop in place, parents can get through a full day without wearing themselves out.

We liked this rhythm so much that we stopped by the lounge for coffee again the next morning before checkout. Being able to squeeze in "one more time" before leaving is one of the great things about a fully self-contained property.

Building a snowman in the outdoor snow play area

Outside, there's an age-based play area called "NASOBIBA," and since it happened to be snowing during our stay, we just went out into the yard and built a snowman. For our 3-year-old, the chance to touch snow at all is precious, and it was one of the moments that made the trip worth it.

At first she was building snowballs with her gloves on properly, but as tends to happen with a 3-year-old, within about 10 minutes her gloves were soaked through. She started saying "cold!," so we went back to the room, swapped in a spare pair of gloves, put her coat back on, and headed back out. How close you are to somewhere you can swap gear makes a huge difference to how comfortable snow play actually is. At a typical sightseeing spot for snow, you'd have to go all the way back to the car to change gear, and that alone is often enough to wreck a kid's mood.

Having a snow play zone right on the hotel grounds really mattered, because:

• You can just go back to the room once you get cold
• You can quickly grab dry gloves to replace wet ones
• A bathroom nearby is reassuring with a young child
• Parents can rest indoors once they're tired too

Having all four of these in place is what determines how satisfying snow play actually ends up being. Without them, snow can easily turn into "a hassle" instead.

In the end, our snowman came together as a two-tier build — head and body. Our daughter wanted to give it eyes, so she picked up a twig and a pine cone lying in the snow to make a face — and this whole sequence seemed to be the best possible experience for a 3-year-old. Even after we got home, she kept saying "I want to build a snowman again." Creating a moment that clearly sticks as a memory of a winter trip was a real win from choosing this property.

We've put together how to gear up and plan for a winter family trip separately in our winter family travel guide. Spare gloves, waterproofing spray, how much of a change of clothes to bring — underestimate any of these and you'll end up in tears on-site.

Food: Tochigi beef sukiyaki, and our daughter glued to the colorful donuts

Dinner was buffet-style. What stuck with us most was the Tochigi beef sukiyaki. A property that actually serves proper local ingredients earns real trust. It was good enough that my wife and I said, "the trip was worth it just for this."

The sukiyaki came in a portion generous enough to go back for seconds. We could order several rounds without issue, and enjoyed the local ingredients not just as a small taste but at a level that felt genuinely satisfying. The usual challenge with buffets is that adding more dishes tends to dilute the quality of any single one, but Grand Mercure Nasu's dinner clearly had one signature dish to anchor the whole spread, which made it stand out among buffets we remember.

Beyond the sukiyaki, the menu range was fairly broad too. There was a Japanese section (grilled fish, simmered dishes, pickles), a Western section (pasta, grilled items), a salad bar, and a dessert corner, so you're guaranteed to find something a 3-year-old can eat. Our daughter's meal basically came down to plain rice, fried chicken, and fruit, but she still seemed perfectly satisfied.

The donut corner our daughter couldn't tear herself away from

For the adults, the star of dinner was the Tochigi beef, but for our daughter, it was overwhelmingly the donut corner.

Rows of small, colorful donuts were displayed right at kid-eye height. That's almost unfair. Colorful things, right in a 3-year-old's line of sight and at a height she could grab herself — there's no way she wasn't going to go for it.

It's easy for adults to write off "buffet sweets" as an afterthought, but when you're traveling with kids, how excited your child gets directly shapes how satisfied you feel about the whole stay. Our 3-year-old skipping off on her own to say "one more donut!" meant we got a few relaxed minutes to actually eat. The donut corner is a design choice that clearly never misses.

Breakfast was also a buffet, with a standard mix of Japanese and Western dishes. There was a made-to-order omelet station, and our daughter lined up saying "one more!" A dish made right in front of you becomes pure entertainment for a 3-year-old, so a live cooking station at a buffet is a quietly important detail for families.

We've covered mealtime tips for traveling with a 3-year-old separately in our tips for traveling with a toddler, but what's within a child's own reach at a buffet is a checkpoint that shouldn't be underestimated when choosing a hotel.

The bath and spots outside the hotel: what gave us pause, and what else there is to enjoy

Here, I'll cover both what gave us pause (the bath) and the extra range of things to enjoy outside the hotel. Knowing both an honest take — not just the good parts — and the appeal of the Nasu area once you step outside the hotel should make planning your own stay easier.

The bath: fine. Though a poorly sealed door left us cold for about 5 minutes

Honestly, the bath was just fine. The facilities and atmosphere of the communal bath were standard, and if you're expecting something special, it's better not to set expectations too high. It's best to accept upfront that this isn't competing with hot spring inns that make their name on water quality or an open-air view — places like Nyuto Onsen or Kurokawa Onsen that specialize purely in hot springs.

One thing that bothered us was that the doors around the changing area were a little poorly sealed, letting in a cold draft. At a mountaintop resort in winter, the outside air temperature is low, so getting chilled here can be a genuinely uncomfortable moment when you have a young child in tow.

Specifically, the roughly five minutes it took to undress our daughter, undress myself, and actually get into the bath were the coldest part. Getting a 3-year-old ready inevitably takes time, and drying her off and changing her into pajamas afterward takes about as long too, so altogether we spent close to 10 minutes fighting off that draft. Adults alone wouldn't even notice it, but traveling with a young child makes you think harder about the risk of "the moment they get cold."

Here's what we did about it:

• Sped through our daughter's changing in the locker room as fast as possible
• Used two towels to dry off quickly
• Saved the real skincare routine and hair drying for back in the room
• Kept our time in the communal bath shorter than usual

Those four things got us through it. Not lingering in the bath, and getting out fairly quickly once you're warmed up, felt like the right call for winter in Nasu. It's probably best to think of Grand Mercure Nasu as a property whose main draw is the play area, the food, and the overall stay experience, rather than the bath. We've written separately about a 3-year-old's first time in a hot spring bath in our hot spring debut guide, but if you want your child to really enjoy their first communal bath, it's safer to pick a property with a warmer changing area.

Outside the hotel was fantastic too: Italian food, wineries, and a zoo

One more thing worth mentioning is how much there is around the Nasu area. This trip was centered on the hotel itself, but Nasu has plenty of spots within a short drive that add real range to your stay. I don't remember every specific shop or facility name, so I'll write this at the level of "here's the kind of thing that's within driving distance."

Nasu is known as an area with quite a few restaurants run by chefs who relocated there. We've stopped by some on a separate occasion (not this trip), and within roughly a 15-30 minute drive of the hotel, there are proper Italian restaurants and cafes renovated out of old farmhouses scattered around. Plenty are kid-friendly, with kids' menus or tatami seating available at some. Since dinner at the hotel is fully covered by the all-inclusive plan, you don't actually need to eat out during your stay — but if you're staying two nights or more, eating out for one meal is worth it to get a taste of the range of Nasu's food scene.

Wineries are scattered around Nasu too, and it's worth a visit if you can carve out some adults-only time. We didn't have time for it on this trip, so it's on our list for next time. You could probably work out a combination where one parent lets the kid play at the hotel briefly while the other slips out to pick up some wine.

And then there's the zoo and safari park. The Nasu area has animal-themed spots that a 3-year-old is guaranteed to love, all within driving distance. Between spacious grounds where you can get up close with animals and safari-style setups where you view animals from your car, there's enough variety that this alone can fill an entire extra day.

Our trip this time ended after just one night, but thinking of it as "a stay in the Nasu area" rather than just the hotel alone made us feel this is a place with even more reasons to come back. Next time, we're planning two nights: day one fully enjoying the hotel, day two stopping by an animal-themed spot before heading home.

Checking out the next morning, and what to remember for next time

Our daughter woke up early the next morning, so we headed straight to the breakfast buffet. We got excited over the omelet station mentioned earlier, our daughter made four more trips to the donut corner, and after two cups of coffee, we headed back to the room to pack.

Checkout went smoothly too. Even during what could be a busy time slot, multiple staff members were handling the front desk, and our daughter's mood never fell apart waiting in line. Bell staff carried our luggage to the car, so all we had to do was walk our daughter to the parking lot holding her hand — a relief right up to the very end.

On the drive home, our daughter kept saying from the back seat, "I want to go horse-riding again," "I want to build a snowman" — and we ended the trip genuinely thinking, "I'm glad we came." A property that gets an unprompted "I want to go again" out of a 3-year-old is, on its own, reason enough to book it by name next time.

Would we go again, and which families would we recommend it to

The answer is yes. Next time, we'd love to go in a different season — summer. We had a full winter of snow play this time, but summer brings its own set of options: the property's signature "Summer Snow Splash" (snow play in summer), an outdoor pool, and bug catching.

Based on this stay, here's who we think it especially suits:

• Families who want a trip that's entirely self-contained within the hotel: if you want to avoid the pattern of sightseeing wearing your kid out
• Families with young kids (roughly ages 2-5): the balance between the indoor play area's toys and the outdoor NASOBIBA area is ideal for this age
• Anyone driving: it's a bit of a distance from the station, so train travelers should plan around a transfer
• Anyone who wants to make full use of the all-inclusive plan: how well you use the lounge as "a place to be" during your stay is the key to satisfaction
• Anyone who wants to turn winter snow into play: having a spot to swap gear close to the room is what determines how comfortable snow play actually is

On the flip side, families who want "a hot spring-focused stay," "mostly walking sightseeing," or "a trip just for the adults" would probably be happier elsewhere. If you're the type who wants to soak in the bath for a full hour, you'll likely get more satisfaction from a property that specializes in hot springs. Our current conclusion, as a family, is to split by season: Nasu for winter, and Awaji Island or Okinawa's Cape Zanpa for summer.

What we wish we'd known before the stay

Lastly, here are some notes — partly for ourselves, partly for any family visiting for the first time.

1. Where the play area is and how big it is: knowing exactly where in the hotel it is, how spacious, and what hours it's open makes choosing a hotel much easier ahead of time
2. The distance between the lounge/bar and the play area: whether kids and parents can stay on the same floor matters more than you'd expect
3. How cold the building gets in winter: an older changing room may have drafts, so be ready to get your child dressed quickly
4. Winter gear for the car: winter tires are essential, 4WD gives peace of mind — don't cut corners on gear with a kid along
5. Spare gloves: snow play soaks gloves through in about 10 minutes — bring at least 2 spare sets for your child
6. How to use the all-inclusive plan: whether you use the lounge as "a place to be" determines how satisfied you'll be
7. Build in one nearby spot: not necessary for one night, but for two nights, plan on one animal-themed or farm-style spot
8. Keep your post-checkout schedule loose: taking your time at breakfast before heading home leaves you with a better feeling all the way to the end

Rates vary quite a bit by season, so we'd recommend comparing availability and pricing on Rakuten Travel or elsewhere before booking. We'd genuinely encourage you to see for yourself what having a play area and a bar inside the hotel is worth to your own family. For us, it's without a doubt become one of the properties we'll return to. If you'd like to weigh other kid-friendly properties too, try narrowing down your options with Kids Stay's property search.
