Japan With a Baby Under 1: Flights, Strollers, Baby Rooms and Ryokan That Make It Easy

The short answer: Japan is one of the easier countries to travel with a baby. Stations and department stores have clean baby rooms, strollers are allowed unfolded on trains, and nappies are never far away. For the ryokan part, book a room with its own bath (babies in nappies usually cannot use the shared baths), ask about infant fees and a baby bed when you book, and choose the earliest dinner sitting.

This guide is about babies under one. For toddlers and older children, see ryokan with kids and our family ryokan guide.

Not medical advice. Check your plans with your baby's doctor before you travel.

Flights: lap or seat, bassinets, passport and visa

Lap infant or own seat. Children under two can fly on a parent's lap, but the US Federal Aviation Administration "strongly urges" an approved child restraint in the baby's own seat, and says buying a ticket for your child is the only way to guarantee you can use one (FAA). Check that your car seat is labelled for aircraft use.

Bassinets. On long-haul flights, many airlines fit bassinets to bulkhead rows for small babies. JAL's take babies up to 10.5 kg, must be requested in advance through its reservation centre, and are limited in number (JAL). Ask as soon as you book. JAL also does not let babies under eight days old fly (JAL).

Passport. Every baby needs their own passport. For US citizens, a child under 16 must apply in person, normally with both parents or guardians present, and the passport is valid for five years (US State Department). Allow time; you will need a passport photo of a baby who will not sit still.

Visa. Japan's short-stay visa exemption works by nationality: the Ministry of Foreign Affairs lists 74 countries and regions whose citizens can visit without a visa (MOFA). A baby on a passport from one of them follows the same rule as you.

Stroller or carrier?

Bring both if you can, and use each where it works best.

• Trains and buses. Japan's transport ministry's standing rule is that strollers can be used unfolded on trains and buses, with the brake on and a hand on the handle; buses may ask you to fold up on some routes (MLIT). Look for the stroller mark on train cars and lifts (MLIT).
• Stairs and escalators. The same guidance asks parents to take the baby out of the stroller on escalators and stairs, and to use a lift or ask for help (MLIT). Big stations have lifts; small rural ones may not.
• Ryokan and onsen towns. Old inns often have steps between rooms, stone paths and slippers-only corridors. A carrier is easier inside the inn and on shrine steps; leave the stroller at the entrance.

Nursing and baby rooms

Japan's public baby rooms (often signed "baby room", akachan or bebi kyukeishitsu) are some of the best anywhere.

• Stations. JR East lists baby rooms inside the ticket gates at stations including Tokyo, Shinjuku, Shinagawa and Yurakucho, with nursing chairs, changing beds and a sink with hot water (JR East). In the west, JR West lists baby care rooms at Osaka, Okayama and other stations (JR West).
• Department stores. Isetan Shinjuku's baby rest area on the sixth floor of the main building has three private nursing rooms, a microwave, hot water for formula and a vending machine with baby food (Isetan). Takashimaya says every one of its stores has a baby rest room and nursing room (Takashimaya).
• Akachan Honpo. Japan's big baby-goods chain, with 130 stores (store list), often in shopping malls. Its in-mall baby rooms have nursing rooms, changing tables and hot water for formula (LaLaport Shinmisato).

In many baby rooms the nursing booths are for women only, while the changing area is open to fathers too (Tokyo Baby Care Map).

Nappies, formula and baby food

• Drugstores and baby shops carry full packs of nappies, wipes, formula and baby food. Akachan Honpo stocks everything from nappies and baby food to clothes and furniture (Good Luck Trip).
• Convenience stores (konbini) are the late-night fallback. Many carry a small pack of nappies in one or two sizes (Tokyo Mom Guides), and Meiji says its ready-to-feed liquid formula is sold at convenience stores as well as drugstores and baby shops (Meiji). Our konbini guide covers the rest of the shelf.
• Honey. Japan's Food Safety Commission warns never to give honey, or food made with it, to babies under one, because of the risk of infant botulism (FSC). Check sweet breakfast dishes and sauces at the inn.

Ryokan with a baby: what to ask before you book

Infant fees. Many inns charge a "facility fee" for a baby who needs no bed and no meals. What the inns we checked say:

Inn	Babies
Ryokan Ryuguden	No charge for ages 0–2; ¥1,650 for 3–5; extra for children's bedding or meals (inn)
Hakone Kowakien TEN-YU	Free under 3; ¥3,000 for 3–6 without meals (inn FAQ)
Nanaeyae	¥1,100 for ages 0–2 without meals or bedding; bedding ¥1,100 (inn FAQ)
Awara Onsen Kofu Yuden Beniya	¥3,000 for an infant with no bedding or meals (inn)
Hatsuhana	¥5,000 for ages 0–6 sharing a bed, which includes rice and miso soup at meals (inn FAQ)

Futon on the floor. A futon removes the risk of a baby rolling off a high hotel bed, and many parents find that a real plus. Safe-sleep guidance still applies: the American Academy of Pediatrics advises a firm, flat sleep surface for the baby, no soft bedding, and sharing a room but not a bed (AAP). So ask about a baby bed. IKI RETREAT has a baby bed, a bed guard and a baby bath (inn FAQ); Izu Nagaoka Onsen Sanyoso says it has no cots or children's futons (inn FAQ). A travel cot from home solves it anywhere.

Private vs shared baths. At most inns, children still in nappies may not go into the shared baths. Hatsuhana asks them to stay out of the tubs in its large and private shared baths, notes there are no changing spaces there, and recommends the bath in your room, where you can add water to cool it (inn FAQ). TEN-YU allows the washing area but not the tubs (inn FAQ); Beniya and Sanyoso ask you to use the bath in your room. That is why a room with its own bath matters more with a baby than for any other trip.

Quiet. Ryokan are quiet places. Beniya says plainly that staff may speak to children who run in the corridors or shout (inn). A crying baby at night is understood; noise in the corridors and dining room is what to watch.

Baby food and kids' dinners. Few inns make baby food, but several will help:

• Hatsuhana does not make baby food but lets you bring your own at no charge and will warm it in the microwave.
• Sanyoso will warm baby food on request and sells children's meals (dinner ¥4,500; a rice, miso soup and fruit set ¥1,400) with five days' notice.
• IKI RETREAT has no children's menu but serves rice and soup free.
• Nanaeyae offers a children's set meal for preschoolers, but asks guests not to bring food in; if you bring baby food, you store and manage it yourself.
• Gora Hanaougi says it prepares a children's meal at any age (inn).

Baby's bedtime vs kaiseki dinner

Kaiseki takes time: Nanaeyae says to allow one to two hours (inn FAQ). If your baby goes down at seven, book the earliest sitting and plan the bath for before dinner.

• Earliest starts we found: 17:30 at Nanaeyae and Sanyoso; 18:00 at IKI RETREAT and Beniya.
• Latest starts: 19:30 at Hatsuhana, Sanyoso, IKI RETREAT and Beniya, if your baby naps late and sleeps through.
• Dinner in the room lets one of you eat while the baby sleeps a few metres away. A few inns serve kaiseki in the room; our honeymoon guide lists some. Ask whether the baby is welcome in that room type before you book.

Healthcare in Japan

• Insurance. Make sure your travel insurance covers the baby by name, including medical evacuation. JNTO has a guide to travel insurance for Japan.
• Emergencies. Call 119 for an ambulance. The Japan Visitor Hotline, run by the Japan National Tourism Organization, answers in English 24 hours a day on 050-3816-2787 (+81-50-3816-2787 from abroad) and helps with illness and accidents (JNTO).
• Finding a doctor who speaks your language. The AMDA International Medical Information Center finds clinics with staff who speak your language, free, on 03-6233-9266, weekdays 10:00 to 16:00 (AMDA). JNTO also has a guide for when you feel ill.
• Medicines. Bring any medicines your baby's doctor recommends, with the dosing instructions.

Not medical advice. Ask your baby's doctor about travel, vaccinations and medicines before you go.
