forumWhat families say

Rakuten Travel rating 4.37 out of 5 (1,647 reviews). Among families with children, guests report that their kids had a blast in the pool and were amazed by the lavish dinner buffet. Guests also praise being able to see the fireworks from their room. Reviews say the pools show their age but feel clean. On the downside, one point raised is that the room had no body-washing sponge or razor.

Overview

Ryugujo Spa Hotel Mikazuki Fujimitei faces Tokyo Bay in Kisarazu, and all 219 of its ocean-view rooms come with a terrace and a semi-open-air bath. Rooms range from the 52 sq m Standard Room to the 100 sq m VIP Suite, and all are Japanese-Western rooms that combine a Japanese-style tatami room with beds, sleeping up to 4 to 6 guests depending on the type. Co-sleeping is accepted for up to 3 children, and with the course dinner, children aged 4 to 6 who have not yet started elementary school are served a kids' meal. Staying guests can use the indoor and outdoor pools and the water slide in the separate Spa Wing free of charge on the day of their stay.

Rooms

All 219 rooms have ocean views over Tokyo Bay, with a terrace and a semi-open-air bath. The in-room baths are not onsen. The Standard Room is a 52 sq m Japanese-Western room that pairs twin beds with a 6-tatami Japanese-style tatami room, sleeping 2 to 4 guests. The Special Room is a 62 sq m Japanese-Western room with twin beds and an 8-tatami tatami room, sleeping 2 to 5 guests. The VIP Suite is a 100 sq m Japanese-Western room with twin beds, a 10-tatami tatami room and a 4.5-tatami anteroom, sleeping 2 to 6 guests. Because each of these rooms has a tatami area, it is easy to find a spot to put a small child down to sleep or let them play. The Comfort Room, renovated on March 18, 2026, is a 52 sq m Japanese-Western room with two semi-double beds measuring 120 cm wide by 195 cm long, plus one sofa bed and either one futon set or one mattress, sleeping 2 to 4 guests. The Superior Room is a 62 sq m twin with two semi-double beds and two sofa beds. All rooms are non-smoking, and smoking is allowed only in the designated smoking areas in the building. The guest rooms are equipped with a humidifier.

Dining

Dinner is a buffet of about 60 Japanese, Western and Chinese dishes at the restaurant Sakura, from 5:30 p.m. to 8 p.m. (last order 7:30 p.m.). Breakfast is also a Japanese and Western buffet, from 7 a.m. to 9:30 a.m., including dishes made with local clams, nori seaweed and other ingredients. On some plans, dinner is instead a course blending Japanese and Western cuisine at All Day Dining Nagi; in that case, elementary school children are served their own dedicated meal, and children aged 4 to 6 who have not yet started elementary school are served a kids' meal. On this plan, breakfast is a semi-buffet at Nagi, from 7 a.m. to 9 a.m. Guests with allergies should note them in the requests field when booking, as requests may not be possible to accommodate on the day. Both breakfast and dinner are served in the restaurants, and in-room dining is not available.

Baths

The communal bath at Fujimitei is made up of Amanogawa, five tiered open-air baths looking down over a spectacular view; Tenku no Yu, three tiered baths; and the Pure Platinum Bath and the K18 Gold Bath. Tenku no Yu is open from 3 p.m. to 9:30 a.m. the next morning. Amanogawa, the Pure Platinum Bath and the K18 Gold Bath are open from 3 p.m. to 10 p.m., and again from 5 a.m. to 9:30 a.m. the next morning; Amanogawa may close at short notice depending on the weather. There is also a communal bath in the separate Spa Wing, which staying guests can use free of charge on the day of their stay. Please note that onsen supply has been suspended for the time being because of emergency maintenance of the hot spring equipment, but the communal baths themselves remain open as usual. The semi-open-air baths in the guest rooms are not onsen. There is no private-hire bath and no sauna. With the semi-open-air bath in your room, you can soak with just your child, so you still have somewhere to bathe even while your baby is too young for the communal bath. Whether children who are not yet out of diapers may enter the tubs in the communal bath is not listed in our information, so please confirm in advance.

Play Areas and Pools

Staying guests can use the spa facilities in the separate Spa Wing free of charge from 11 a.m. on the day of their stay (a separate charge applies the following day). The indoor pool is open from 10 a.m. to 7 p.m., and the outdoor pool, Ocean Spa, from 10 a.m. to 6 p.m.; it has a children's pool. Ocean Spa is open year-round except in stormy weather. Aqua Park has a 70 m water slide, and the outdoor pool area also has a lazy river 250 m around (summer season only). There is no age restriction for the pools, but children who are not yet out of diapers are asked to wear swim pants together with their swimsuit. The outdoor pool is 110 cm deep. Within Ryugujo there is a pet zoo, Animal Resort NOAH, where you can meet sloths, otters and other animals, and feed them for an additional charge (10 a.m. to 5 p.m., closed Wednesdays). Some stay plans include admission tickets. The separate wing also has Omatsuri Land, so between the communal baths and the pools, you can spend a whole day without leaving the complex. Fireworks events are held every Friday, Saturday and Sunday, and you can watch them from your room too (they may be canceled in stormy weather). The Spa Wing and Omatsuri Land have closed days, and during those periods no facilities other than Fujimitei can be used, so please check your dates.
