Japan with kids: what children pay, the best age to go, strollers, car seats, hotels and nursing rooms

Is Japan good for kids?

JNTO's guide to travelling with children asks whether a trip to Japan with kids will be easy, and replies: "The answer is a resounding yes!" It calls Japan's major cities "surprisingly family-friendly", and the reasons are practical: free or half-price fares for children, nursing rooms in department stores and stations, space for strollers on city trains, and family restaurant chains that welcome small children.

The same guide is frank about the harder parts, and they are worth planning around:

• Stairs outside the cities. "Outside of major cities, older infrastructure means more walking and stairs", and JNTO suggests planning extra time or renting a car.
• Stroller or carrier. Where there is no elevator or ramp, JNTO notes that "babywearing may be a more convenient choice", and parents in Japan often switch between the two depending on the day.
• Crowds. "crowds can build up during rush hours and peak travel times"; JNTO's advice is to avoid trains and popular spots at the busiest hours.
• Beds. Many ryokan put the whole family on futons on the tatami, and JNTO warns that "Western-style beds or travel cribs might not always be available".

What children pay in Japan

Japanese railways price children by age, and the rules on JR and the Tokyo subway are almost the same. This table uses JR Central's and Tokyo Metro's published age rules and the official prices:

The Shinkansen prices are smartEX's for a regular-season day; children's prices also vary by season. A child's fare is half of each part of the adult fare, and "5 yen is rounded down", which is why it can come to slightly under half.

Two details decide the borderline cases. JR counts a 12-year-old still at elementary school as a child, and a 6-year-old who has not started school as an infant, but those exceptions "apply only when the 'elementary school' is established under the Japanese law", so for most visiting families age alone decides. The Japan Rail Pass is stricter: its price page defines a child as "those aged 6 to 11 at the time of use (elementary school students aged 12 or older are considered 'adults')".

Beyond the railways:

• Domestic flights. ANA takes 25% off its Flex, Standard, Simple and Sale fares for children aged 2 to 12. Peach's booking form has three age groups: Adult (12 and over), Child (2 to 11) and Infant (0 to 23 months). This site does not quote their children's prices; check them when you book.
• The departure tax. Japan's international tourist tax rose to 3,000 yen per departure on 1 July 2026 and is collected in the airfare. Children under 2 are exempt.
• Customs. Children under 6 get no duty-free allowance "except for items that are clearly regarded as for children, such as toys", and nobody under 20 gets an allowance for alcohol or tobacco.
• Hotels and ryokan. Each hotel sets its own children's prices and the number of guests a room can take, so enter every child's age when you search; more on that below.

For a family of two adults and two children aged 6 to 11, reserved seats on a Nozomi from Tokyo to Kyoto cost 41,900 yen one way: 2 × 13,970 + 2 × 6,980.

The best age to take kids to Japan

There is no single best age, but the price changes on particular birthdays:

On price alone, the years before the sixth birthday are the cheapest for travelling by train, as long as a child rides on a lap, and children under 2 also skip the departure tax. They are also the stroller and nap years, when JNTO's points about stairs, crowds and futons matter most. From 6, children pay about half on the railways, which still adds up on a long Shinkansen ride.

Trains and the Shinkansen with kids

Japan's trains are often the highlight of a trip for children, and they are easy to use with a family as long as you know the ticket rules.

Shinkansen tickets for children

A child under 6 rides the Shinkansen free on your lap. Give them a reserved seat of their own and they need a child ticket: JR Central's Nozomi page says that if a child aged 1 to under 6 or a baby under 1 "occupies an ordinary car reserved seat or a green car reserved seat, a child fare and fee are required". From 6, every child needs a ticket. On smartEX, the official booking site for the line from Tokyo to Kyoto, Osaka, Hiroshima and Fukuoka, which books up to 6 people at once, the regular-season prices for a reserved seat on a Nozomi are:

JR Central puts Kyoto about 2 hours from Tokyo, a long time on a lap for an active three- or four-year-old, so on longer rides the extra seat can be worth paying for. Our Shinkansen tickets guide covers booking, seat types, changes and refunds.

Strollers on the Shinkansen

On the Tokaido, Sanyo and Kyushu Shinkansen, JR Central lets you bring a stroller without a reservation: up to 250 cm (three sides added together), it goes on the overhead rack or in a deck baggage storage area. The space behind the last row of seats in a car is different: it belongs to the passengers who booked those seats, so JR Central recommends booking one if you want to keep the stroller there. A seat with an oversized baggage area costs nothing extra; on smartEX, book it on the day seats go on sale, one month before, because these seats "cannot be reserved through after-hours or pre-sale requests".

City trains and the subway

JNTO: "On most urban trains, you'll find a space that can easily accommodate a stroller." Certain carriages are designated for strollers and wheelchairs, and you can find them from the platform markings, which show carriage numbers and pictograms for stroller or multipurpose spaces. "Most major stations are also equipped with elevators", and JNTO suggests selecting the wheelchair-accessible option when you plan a route in apps like Google Maps. Avoid the morning and evening rush hours with a stroller.

Three ticket points for children in Tokyo:

• Single rides. Children aged 6 to 11 pay 90 to 170 yen a ride on Tokyo Metro with a paper ticket, or 89 to 162 yen with an IC card, about half the adult fare of 180 to 330 yen (178 to 324 yen).
• IC cards. JR East sells a child version of the Welcome Suica card for visitors, valid until the 31 March after the child's twelfth birthday, on showing the child's passport. See Suica and other IC cards.
• Paying by credit card. Tokyo Metro's tap-to-ride service, which lets you touch a contactless credit card at the gate, charges the adult fare only, so a child needs their own ticket or card. See cash or card.

For a few days of sightseeing, the Tokyo Subway Ticket costs 500, 750 or 1,000 yen for a child for 24, 48 or 72 hours; our Tokyo Subway Ticket guide works out when it pays off.

The Japan Rail Pass for children

On the official site a child's Japan Rail Pass costs 25,000 yen for 7 days, 40,000 yen for 14 days and 50,000 yen for 21 days (Green Car 35,000, 55,000 and 70,000), half the adult price. From 1 October 2026 overseas agents charge 27,000, 42,000 and 53,000 yen for a child. Like the adult pass, it does not cover the Nozomi or Mizuho without an extra NOZOMI MIZUHO Ticket, and it pays off only if the family makes several long rides within the pass's days. A child under 6 who rides free needs no pass. Our Japan Rail Pass guide works through the sums.

Strollers, buses and getting around

JNTO: "Buses are stroller-friendly too—many cities use low-floor, non-step buses that tilt toward the curb when stopping, making it easy to roll your stroller right on." The rules for keeping a stroller open are set by each bus operator. Yokohama City's buses are one example — "You can travel on city buses without having to collapse your stroller" — with these conditions:

• Tell the driver that you are boarding without folding the stroller. On a bus that cannot be boarded at the front, use the rear door.
• Secure it yourself in the securement area, facing opposite to the direction of travel, with the belt attached to the passenger seat; if you cannot, ask the driver for help.
• Child harnessed, brake on, and a hand on the stroller throughout.
• Be ready to fold it. Strollers may have to be collapsed if the bus is crowded, if a wheelchair user is aboard, if the stroller is a two-seater, oversized or cannot be secured with the belt, or if three or more passengers with strollers are aboard ("There is usually only space to secure two strollers at the same time, and some buses have space for only one"). The driver will then ask other passengers to help you find a seat.

You do not always need to bring your own stroller. JNTO: "Many major sightseeing spots—like theme parks, large parks, museums, aquariums, airports, and even some train stations—offer free or low-cost stroller rentals for families", and there are also rental services that let you reserve a stroller for the whole trip.

For the big bags, send them ahead with a luggage forwarding service and travel with day bags and the stroller; see luggage in Japan. For a short hop with tired children, see taxis in Japan, and for child fares on city and highway buses, our bus guide.

Flying within Japan with kids

ANA takes 25% off its Flex, Standard, Simple and Sale fares for children aged 2 to 12. For families it adds:

• Seats together and bassinets. "If you wish to select seats in advance with children or in case you would like to use bassinets, please make a reservation with a fare that is eligible for advance seat reservation."
• Free baby gear. A child under 2 without a seat has no baggage allowance of their own, but a fully collapsible stroller, a carrying basket and a car seat are carried free.
• Cabin bags. A child safety seat, "Bags containing infant or child items necessary for the flight" and a "Portable cradle for use with infants or children" do not count towards the cabin baggage allowance.

Peach, a low-cost airline, books passengers in three age groups: Adult (12 and over), Child (2 to 11) and Infant (0 to 23 months). This site does not quote children's or infants' fares for either airline; check them when you book. Our domestic flights guide compares the airlines, baggage rules and airports.

Car seats, rental cars and taxis

Under Article 71-3 of the Road Traffic Act, a driver must not drive with a child under 6 who is not in a child seat. The National Police Agency explains why: the fatality rate of children not using a child seat is about 5.3 times that of children using one properly. It also advises that a child of 6 or over should keep using a child seat if their build means the seatbelt cannot be worn properly.

• Rental cars. JNTO notes that "Rental car companies often offer child seats as an optional extra." Reserve one for each child when you book the car, and give the child's age and weight so the branch can set aside the right size. See renting a car in Japan and driving in Japan.
• Taxis and buses. The duty does not apply to the driver of a taxi or bus carrying a child as a passenger: the Road Traffic Act Enforcement Order lists this among its exemptions (Article 26-3-2). So a taxi is not required to carry one. If you plan long rides by taxi or a private transfer, ask the company when you book whether it can provide one, or bring a travel seat of your own.

Hotels and ryokan with kids

Japanese hotels are strict about numbers. Each room takes a fixed number of guests, and a guest who is not on the booking can be refused at the desk, so enter every child and their age when you search, even a baby who will share your bed. Each hotel decides whether a small child can share an existing bed and what a child's breakfast costs, so the price can change with the ages you enter.

• Hotel rooms. A Western twin room in a city hotel is small and often limited to two guests. Look for family, triple or quad rooms, connecting rooms or an apartment hotel. Our guide to where to stay in Japan suggests family-friendly areas in Tokyo, Osaka and Kyoto, and hotels in Japan covers booking.
• Ryokan. A Japanese-style room is often the easiest way to keep a family together. JNTO says many ryokan "use futons on tatami mats for the whole family", and advises you to "be sure to check ahead about bedding options". Ryokan usually price per person and prepare meals for each guest, so book the exact number of people, including children, and ask whether there is a children's meal. See staying in a ryokan.
• Baths. The large communal baths at an onsen separate men and women. Ask whether the inn has family bathing hours or a private bath you can book (kashikiri-buro), so that the whole family can bathe together.
• Capsule hotels. Not for families: a family cannot stay together in one, and most capsule hotels do not take children. See capsule hotels.
• Accommodation tax. Tokyo, Osaka, Kyoto and several other cities add a local tax per person per night, and their rules differ on children, so ask the hotel when you book. See accommodation tax in Japan.

Food, nursing rooms and baby supplies

JNTO: "You'll find nursing rooms in all the right places—department stores, stations, malls, and beyond." Many offer more than a changing table: JNTO lists "hot water dispensers, microwaves for baby food, private nursing cubicles, soft changing mats, and even plush nursing pillows". Its examples are in Tokyo and Yokohama: "At Ginza's Mitsukoshi department store, you'll find baby scales and standing-height changing tables, while both Sogo Yokohama and Isetan Shinjuku offer dedicated baby feeding areas complete with highchairs, and Keio Shinjuku even boasts a toddler play space."

• Breastfeeding. JNTO says that "breastfeeding discreetly in public is accepted in Japan (most moms use a cover)", and that a nursing room can be the more comfortable option.
• Finding a nursing room. JNTO notes that "many parents use apps like the free Mama Papa App to locate the nearest nursing room when out and about".
• Baby food. "Baby food is also easy to find at most convenience stores." If your child is used to a particular brand of formula or nappies, bring enough for the first days.

Eating out is easier than many parents expect. JNTO says that "most restaurants in Japan (as long as they're not upscale or highly formal) tend to be welcoming toward children and will do their best to accommodate families." Japan also has its own word for casual chain restaurants built around families, fami-resu, short for family restaurants, which JNTO describes as "often offering affordable meals, fast service, and little extras like toys, coloring sets, or fun character-themed menu items". Its examples are Saizeriya, Gusto, Denny's, Sushiro and Hama Sushi; the last two are conveyor-belt sushi chains. For what to order and how to eat it, see our guide to what to eat in Japan.

If your child has a food allergy, our Japanese allergy card generator makes a card in Japanese to show restaurant staff.

Passports, Visit Japan Web and customs with kids

The paperwork is the same for children as for adults, one person at a time:

• Passports. JNTO's rule is that "All foreign visitors must have a valid passport", so every child, babies included, needs their own. Our Japan visa guide explains who can visit without a visa.
• Visit Japan Web. The government's online service for immigration and customs lets one account carry the whole family: "You can register up to 10 family members traveling with you." Each person still has their own details and their own code, because "Entry and return procedures will be processed one person at a time." See how to use Visit Japan Web.
• The customs gate. At the electronic customs gates the procedure is required for each person, but Japan Customs' leaflet says that "small children less than 100 cm tall can pass through the gate with a family member".
• Duty-free allowances. As set out above, children under 6 get an allowance only for things clearly meant for children, such as toys, and nobody under 20 gets one for alcohol or tobacco. Our guide to Japan's rules for tourists has the adult allowances.
• Medicine. If your child takes regular medicine, check the quantity limits in taking medication to Japan before you pack it.

When to go with kids

smartEX's season calendar charges the most for a reserved seat on its top-peak days. In 2026 these were 1–6 May (Golden Week), 7–8 and 15–16 August (around the summer Obon holidays) and 18–23 September; over the New Year they are 29–30 December 2026 and 2–3 January 2027. Around those dates, three things matter for families:

• Book seats early. Reserved seats go on sale at 10:00 a.m. Japan time one month before. In the busiest holiday periods every Nozomi is reserved-only and passengers with non-reserved tickets have to stand, which is hard with small children; JNTO announced one such period from 26 December 2025 to 4 January 2026.
• No early-booking discount. smartEX's Hayatoku fares are "not available during busy periods (Golden Week, Obon, the New Year's holiday, etc.)".
• Weekdays are cheaper in autumn. From 9 October to 29 November 2026, every Friday, Saturday and Sunday, plus the holiday Mondays 12 October and 23 November, is a peak day on smartEX, 200 yen dearer per adult reserved seat than a regular-season weekday (400 yen on a trip across two lines, such as Tokyo to Hiroshima).

The full season calendar is in our Shinkansen tickets guide. For public holiday dates, see Japan public holidays, and for the weather and what to pack, what to wear in Japan.

What a family trip costs

Here are the official prices for a family of two adults, an 8-year-old and a 4-year-old, on regular-season days:

For a trip from Tokyo to Kyoto and back, the Japan Rail Pass would cost this family 55,160 yen more than smartEX tickets, and it would still need the NOZOMI MIZUHO Ticket on a Nozomi; it pays off only with several more long rides in the same week. For hotels, this site does not quote one: prices depend on the city, the season and how each hotel charges for children. Our trip budget calculator adds up a whole trip, and how much a trip to Japan costs shows what visitors spent.

Before you fly

• Packing. Work through our Japan packing list and pre-trip checklist.
• Luggage. Send big bags ahead so that your hands are free for children and the stroller; see luggage in Japan.
• Insurance. Make sure every child is named on the policy; our travel insurance guide covers what to look for.
• Data. Maps, train apps and translation all need a connection; see eSIM for Japan.
