Kids Facilities

Yochiyochi baby lounge

Ages 0-3Indoor

A play lounge inside the ryokan where babies and their parents can play to their hearts' content. It is generously sized and well stocked with toys, and because so many families with babies spend their time here during their stay, there is less worry about a child crying in the lobby - part of what makes Monya what it is.

Free baby and kids' items to borrow

Ages 0-3

Without charging any separate facility fee, the ryokan lends out dozens of baby and kids' items free of charge. The lineup lets you travel with a very young baby while carrying far less, and it even includes a baby-bottle washing and sterilizing service.

Baby food and kids' meals supervised by the head chef

Ages 0-6Indoor

Baby food whose recipes the head chef supervised is prepared in an early stage (vegetable purees) and a mid-to-late stage (simmered white fish and vegetables, among other dishes). None of it uses egg or dairy. With a baby plan the baby food is free of charge, and rice, soft-cooked rice or rice porridge is also prepared free of charge to go with the dishes. Kids' meals and celebration menus such as an okuizome first-meal tray and an issho-mochi rice cake are available as well.

Hikari no Yu view bath and Toki no Yu garden bath

Ages 0-12Indoor

There are two onsen bathhouses: the view bath Hikari no Yu, looking out toward the Nojimazaki Lighthouse, and the garden bath Toki no Yu, which overlooks a small courtyard garden. Hikari no Yu is a shallow 45 cm deep, so you can lie back in it and younger children can bathe with peace of mind. The spring water is a sodium chloride and bicarbonate spring. Baby items are provided at the baths as well.

Nagi no Yu onsen family bath (free, private-hire)

Ages 0-12Indoor

An onsen family bath on the first floor. Flooring the washing area with tatami helps prevent injuries if a child falls, as well as heat shock, so the whole family can bathe with peace of mind - from babies to anyone unsteady on their feet. There is no charge to use it, and it is booked on a first-come, first-served self-service system by writing your preferred time on the chart at the bathroom entrance.

Overview

Kisui no Yado Monya is an onsen ryokan in Shirahama, at the southern tip of the Boso Peninsula, where every room has an ocean view. It has held Mikihouse Child Rearing Institute's "Welcome Baby" certification for more than 10 years, and more than 70% of its guests are families with babies or pregnant travelers, making it a ryokan devoted to travel with young children. The baby lounge Yochiyochi for children under 3, baby food in early and mid-to-late stages supervised by the head chef, an extensive range of free baby items to borrow, a shallow 45 cm-deep view bath fed by the onsen, and a tatami-floored onsen family bath all come together to support a first trip with a baby from start to finish.

This onsen ryokan stands in Shirahama, at the southern tip of the Boso Peninsula in Minamiboso, Chiba, and every room has an ocean view. Beyond the windows lies a wide panorama of the Pacific with Izu Oshima on the horizon, and you spend your stay wrapped in the sound of the waves and the scent of the shore.

More than 70% of guests come with a baby or are pregnant

Monya has spent years refining hospitality tailored to families with babies and to pregnant guests, guided by the belief that a ryokan that satisfies a baby is a kind one for the whole family. It received Mikihouse Child Rearing Institute's "Welcome Baby" certification in 2010 and has held it for more than 10 years. More than 70% of its guests really do arrive with a baby or are pregnant, which tells you how family-friendly it is.

The Yochiyochi baby lounge and the baby concierges

Inside the ryokan there is a dedicated playroom called Yochiyochi for children under 3, generously sized and well stocked with toys. Some staff members have completed the Japan Child Rearing Support Association's baby concierge leader training course and are experts in caring for babies, and staff who are raising children of their own work here too. If anything worries you during your stay, you can ask a staff member wearing the dedicated badge. The ryokan can also introduce you to a local babysitting service, so parents can make time for themselves.

Baby food and kids' meals supervised by the head chef

The baby food, whose recipes the head chef supervised, comes in an early stage (purees of carrot, spinach and pumpkin) and a mid-to-late stage (simmered white fish and vegetables, sweet potato chakin, and more), and none of it uses egg or dairy. With a baby plan the baby food is free of charge, and rice, soft-cooked rice or rice porridge is also prepared free of charge to go with the dishes, with advance reservation required. A grinding bowl and a food cutter are available to borrow, and the ryokan also prepares kids' meals as well as celebration meals for milestones, such as an okuizome first-meal tray and an issho-mochi rice cake.

An extensive range of free baby items to borrow

Without charging any separate facility fee, the ryokan offers dozens of items to borrow free of charge, including a bouncer, a Bumbo seat, a baby chair with a table, a baby bath chair, bath toys, a small nap futon for infants, a blackout dome for babies, a baby monitor, a baby thermometer, a baby-bottle washing and sterilizing service and a formula-preparation pot. Powdered formula is the one thing they ask you to bring yourself, in the brand your baby is used to.

A shallow onsen view bath and a tatami-floored onsen family bath

There are two onsen bathhouses: the view bath Hikari no Yu, which looks out toward the Nojimazaki Lighthouse and is a shallow 45 cm deep so younger children can bathe with peace of mind, and the garden bath Toki no Yu. Both alternate between men and women, and are open from 3 p.m. to midnight and from 6 a.m. to 9:30 a.m. The spring water is a sodium chloride and bicarbonate spring. On the first floor there is also the onsen family bath Nagi no Yu, whose washing area is floored with tatami to help prevent falls and heat shock, so everyone from babies to guests who need support can use it. It is free of charge and booked by a self-service system, for 50 minutes at a time. There are also the design private-hire baths Rei and Gen on the third floor, which are not fed by the hot spring and cost 2,200 yen for 50 minutes with advance reservation.

Rooms

The 8 to 9 room types each have their own character, and all of them have ocean views. Choose to suit how your family travels: detached rooms with an open-air onsen bath, where you need not worry about night-time crying; ocean-view twin rooms with a semi-open-air bath (a baby bath chair is provided); or Irodori-tei, designed specifically for families with children, with a play mat, toys and a beanbag chair. All rooms are non-smoking, and Wi-Fi is free.

Notes on the baths and the building

There is no elevator in the building, so you move between floors by stairs, and reaching the communal baths means going up and down them. Take care with strollers and with your footing. Late checkout at 10:30 a.m. is available.
