Shinkansen with a Baby: Where to Sit, Feed, Change and Store the Stroller

A few hours on the Shinkansen with a baby can feel like a big unknown. Where do you feed them? Where do you change a diaper? What happens to the stroller? The good news is that there are answers to all three. The catch is that the details differ by line and by train.

So we went through the official pages of JR Central, JR West, JR Kyushu and JR East and pulled out what matters with a baby. Where we couldn’t confirm something on an official page, we say so, and tell you where to ask.

Which car and seat should you book with a baby?

If we were booking for a baby, we’d look for three things, in this order:

1. The car with the multipurpose room (or the car next to it), so you don’t have to walk the length of the train to feed.
2. A toilet with a diaper-changing table nearby.
3. An aisle seat close to the deck (the vestibule area between cars, by the doors), so you can step out quickly if your baby needs a walk.

Your ticket shows a car number, written 号車 (gōsha, “car number”), and a seat. If you’re not sure where to stand on the platform, station staff can point you to the right spot.

Here is what the official pages say, line by line. “Not stated” means we could not find it on the official pages we checked. It does not mean the train has no such facility.

Tohoku, Hokkaido, Joetsu (JR East)	E5-series trains (Hayabusa, Hayate, Yamabiko, Nasuno) have one. We couldn't confirm the car number, so ask a crew member	Not stated in the text of JR East's pages. Ask a crew member	Not part of this reservation system. JR East's own luggage rules: check JR East's official site	Not stated	[16] [9]

Two things to keep in mind:

• Car numbers can change on the day. JR West notes that if a different train set has to be used because of a disruption, the multipurpose room may not be available ^[2].
• For JR East lines (to Sendai, Aomori, Hokkaido, Niigata and so on), JR East says its E5-series trains have a multipurpose room ^[16], but we couldn’t confirm which car from the text of its official pages. Ask a crew member once you board.

Is there a family car on the Shinkansen?

Sometimes. On set dates, JR Central runs a “family car” (お子さま連れ車両, okosama-zure sharyō) on some Nozomi trains between Tokyo and Shin-Osaka. It is Car 12, a standard reserved car, and you book it through JR Central’s EX online service. There are no oversized-baggage seats in that car, and it can’t be used with the Japan Rail Pass ^[12]. The dates change each period, so check JR Central’s EX site for the current schedule.

Where can you feed and change your baby on the Shinkansen?

The multipurpose room (tamokuteki-shitsu)

The multipurpose room (多目的室, tamokuteki-shitsu) is a small private room on board. JR Central says it is for passengers who have difficulty walking and anyone who feels unwell ^[3]. JR West says that when no passenger with a disability needs it, you can use it for breastfeeding, changing clothes or if you feel unwell, and that you should ask a crew member if you want to use it ^[1]. JR Central also presents the room on its N700S trains as one you can use for nursing ^[5].

What to expect:

• It isn’t always free. It may be in use or already booked ^{[3] [4]}, and JR West says passengers with disabilities come first ^[1].
• There’s a bed in it that folds away when a wheelchair user needs the space ^[2].
• On the Tokaido Shinkansen, a 2023 news report says JR Central put a QR code at the Car 11 multipurpose room so passengers can call a crew member ^[6].

If we needed the room, we’d mention it to the first crew member we saw after boarding, rather than waiting until the baby is already hungry. JR West itself invites you to ask for it, so you don’t need to feel you’re asking for a favor ^[1].

What to say (show your phone if that’s easier):

Excuse me. Could we use the multipurpose room to feed our baby?

すみません。授乳で多目的室を使わせていただけますか。

Sumimasen. Junyū de tamokuteki-shitsu o tsukawasete itadakemasu ka? (“Excuse me. May we use the multipurpose room for breastfeeding?”)

Diaper-changing tables

On the Sanyo and Hokuriku Shinkansen, JR West says diaper-changing tables are in the Western-style toilets, except some. On the Sanyo Line those toilets are at the Tokyo end of odd-numbered cars. On the Hokuriku Line they are at the Kanazawa end of odd-numbered cars and at the Tokyo end of Car 12 ^[1].

For the Tokaido Shinkansen, we could not find diaper-table locations on JR Central’s official pages. The same 16-car trains run on the Tokaido and Sanyo Lines ^[8], but we’d still ask a crew member rather than assume. This phrase works:

おむつ交換台のあるトイレは何号車ですか。

Omutsu kōkan-dai no aru toire wa nan-gōsha desu ka? (“Which car has a toilet with a diaper-changing table?”)

Feed and change before you board

The easiest diaper change is often the one you do at the station. Some JR West stations have baby care rooms inside the Shinkansen gates, for example at Hakata, Hiroshima, Kanazawa, Toyama and Kokura, and at Shin-Kobe. At some of them you press an intercom and staff unlock the door. Because they are inside the gates, you may need a ticket or a platform ticket ^[18]. JR Kyushu says some of its stations have nursing rooms with nursing chairs, diaper-changing beds and sinks ^[19]. JR East lists baby rooms with nursing chairs, diaper-changing beds and sinks at several Shinkansen stations, for example inside the Shinkansen gates at Tokyo, Omiya and Sendai, and at Niigata, Nagano and Karuizawa ^[17]. Facilities differ by station, so check the station’s page on the rail company’s official site before you go.

Can you stand in the deck area with a crying baby?

The deck (デッキ, dekki) is the space between cars, by the train doors. It’s where the toilets, sinks and luggage areas are.

We could not find an official JR rule or guideline about standing in the deck with a baby. What we’d do: if our baby started to cry and didn’t settle within a minute or two, one of us would take them out to the deck, sway a bit, look out of the door window together, and come back when things calmed down. It gives your baby a change of scene, and it gives you a break from feeling watched.

A few more things we’d plan for:

• Take turns. Agree before you board who does the first deck walk and who does the next. It saves a tense whispered negotiation at the worst moment.
• Time the ride around a nap if you can. A baby who falls asleep as the train pulls out is the best-case scenario, and booking a slightly later train to get there can be worth it.
• Keep a hand free. If you’re standing in the deck with a baby in a carrier, we’d keep one hand free to steady ourselves.

If the ride goes badly anyway, that’s okay. Babies cry on trains everywhere, including in Japan.

Strollers and big luggage: what are the rules?

This is where most of the confusion is. In short: strollers are not covered by the oversized-baggage reservation rule, but the reserved space behind the last row is not free for anyone to use.

The oversized-baggage rule (Tokaido, Sanyo and Kyushu)

On the Tokaido, Sanyo, Kyushu and Nishi-Kyushu Shinkansen, luggage over 160 cm and up to 250 cm in total (length + width + height) counts as oversized baggage. You need to reserve a “seat with oversized baggage area” (特大荷物スペースつき座席, tokudai nimotsu supēsu-tsuki zaseki): a seat in the last row of certain cars, with the space behind it for your bag ^{[7] [9] [10]}. These seats cost the same as a normal reserved or Green seat ^{[7] [9]}.

If you board with oversized baggage without a reservation, you pay a 1,000 yen fee (tax included) and must put it where the crew tells you ^{[7] [9] [11]}. Paying the fee does not guarantee a space: if the seats are sold out, JR West says to book another train ^[9].

This rule applies only to those Shinkansen lines. It does not apply to the Tohoku, Hokkaido, Joetsu or Hokuriku Shinkansen, or to conventional lines ^[9].

What about strollers?

JR Central, JR West and JR Kyushu all say that strollers, sports equipment and musical instruments are not covered by the oversized-baggage rule, so you don’t need a reservation for one. JR Central adds that this applies whatever their size, and also lists wheelchairs ^{[7] [9] [10]}.

But: the space behind the last row is only for passengers who reserved those seats. If you want to put your stroller there, reserve a seat with oversized baggage area. JR says these seats can also be booked by people who need luggage space, for example for a stroller ^{[7] [9] [10]}. One trade-off: with luggage behind you, you may not be able to recline ^{[7] [9]}.

In cars without these seats, other passengers’ ordinary luggage may go behind the last row, but the passenger in that last row has priority ^[9].

Where everything else goes

Where luggage goes on the Tokaido, Sanyo and Kyushu Shinkansen (official pages, checked November 2026)

Luggage size (L+W+H)	Where it can go	Reservation	Source
Up to about 120 cm	At your feet in standard class (Green Cars have footrests, so use the overhead rack)	No	[9] [10]
Up to about 160 cm	Overhead rack (about 42 cm deep on N700-series trains)	No	[9] [10]
Up to 160 cm	Deck luggage areas in Cars 3, 5, 7, 9, 13 and 15 of 16-car Tokaido and Sanyo trains (trial since 1 July 2025)	No	[8] [9]
Over 160 cm, up to 250 cm	Space behind a reserved seat with oversized baggage area (last row of certain cars)	Yes, or a 1,000 yen fee	[7] [9]
Over 250 cm	Cannot be taken on board	-	[7] [9]
Strollers, any size	Not covered by the oversized rule. To use the space behind the last row, reserve that seat	Only if you want that space	[7] [9] [10]

A few details that help with a baby:

• Whether your stroller fits at your feet or on the rack depends on its folded size. Measure it at home and compare with the numbers above.
• The deck luggage areas can be locked with your own IC transport card (such as Suica or ICOCA), though some cards and phones may not work ^{[7] [9]}. Oversized baggage can’t go there ^[8]. The reservation-free use is a trial, and JR Central and JR West will announce when it ends ^[8]. Photos taken before the trial, like the example on this page, show these areas marked “Reservation Required”.
• Crew will help lift luggage onto the overhead rack as far as they can, if you ask ^[9].
• The JR Group limit is two pieces of hand luggage per person, each up to 250 cm in total (length up to 2 m) and 30 kg. Umbrellas, canes and handbags don’t count ^[13].

To ask for help with the rack:

荷物を棚に上げるのを手伝っていただけますか。

Nimotsu o tana ni ageru no o tetsudatte itadakemasu ka? (“Could you help me put this bag on the rack?”)

How to book the last-row seats

On a 16-car Nozomi, these seats are in standard-class Cars 3–6 and 12–16 (five per car) and Green Cars 8–10 (four per car) ^[9]. On 8-car Mizuho and Sakura they are in standard Cars 4, 5, 6 and 8 and Green Car 6 ^[9]. On the 800 series (Sakura, Tsubame), they are the last row of Car 6, and on the Nishi-Kyushu Shinkansen Kamome, the last rows of Cars 1 and 2 ^[10]. There are none in non-reserved cars or in some reserved cars ^[7].

You can book them online through JR Central’s EX service (smartEX), JR West’s e5489 or JR Kyushu’s online booking, at a ticket machine by choosing the seat on the seat map, or by telling the staff at a ticket office. They go on sale one month ahead, like other reserved seats ^{[7] [9] [11]}. On EX, one booking covers up to five people (four in the Green Car), all in the same car ^[11]. With a stroller and a baby, we’d book as early as our plans allow.

Do you need a ticket for your baby?

Children under 6 who sit on an adult’s lap basically ride free. If they use their own reserved or Green seat, you pay a fare and charge for them ^{[1] [12]}. The age groups and limits are explained in our guide to child and infant fares on Japan’s trains.

A simple plan for the ride

Here’s the plan we’d follow for a 2- to 3-hour ride with a baby:

Before you leave the hotel

• Check which car has the multipurpose room on your train (see the table above), and book seats in or near it.
• If you’re bringing a stroller and want the space behind the last row, book that seat now.
• Measure your folded stroller.

At the station

• Arrive with time to spare, especially with a stroller, so you’re not hunting for an elevator in a rush.
• Feed and change your baby in a station baby room if there is one inside the gates.
• Buy water and snacks before you board. Food on board is limited: the Tokaido Shinkansen ended trolley sales in 2023 and its mobile order is for Green Cars only ^[6], the Kyushu Shinkansen ended onboard sales in 2019 ^[15], and on the Sanyo Line mobile order is limited to Green Cars and Supreme Class on 16-car Nozomi and Hikari ^[14].

On board

• Put away the stroller and big bags first, then settle the baby.
• If you’ll need the multipurpose room, let a crew member know when you see one.
• Take turns with deck walks.

Quick checklist

• Which car has the multipurpose room on your train? (Ask a crew member if your line is “Not stated” above.)
• Seats booked in or near that car, on the aisle, near the deck?
• Stroller: folded size measured? Space behind the last row booked, if you want it?
• Oversized luggage (over 160 cm total) on the Tokaido, Sanyo or Kyushu Shinkansen: seat with oversized baggage area booked?
• Fed and changed at the station? Water and snacks bought?
• Phrases saved on your phone?

Questions parents ask

Is there a nursing room on the Shinkansen?

There is a private multipurpose room. JR West says that when no passenger with a disability needs it, you can use it for breastfeeding, changing clothes or if you feel unwell. Ask a crew member to use it. It may not be free if someone has already booked it.

Do I need to reserve a space for my stroller?

No. On the Tokaido, Sanyo and Kyushu Shinkansen, strollers are not covered by the oversized-baggage reservation rule, whatever their size. But the space behind the last row of seats is only for passengers who reserved those seats, so if you want to put your stroller there, book a seat with oversized baggage area.

Where should I sit with a baby on the Shinkansen?

We'd book seats in or near the car with the multipurpose room, close to the deck and to a toilet with a diaper-changing table. On the Sanyo Line, JR West lists Car 11 on 16-car trains and Car 7 on 8-car trains.

Is there a diaper-changing table on the Shinkansen?

JR West says the Western-style toilets on the Sanyo and Hokuriku Shinkansen have diaper-changing tables, except some. For the Tokaido, Tohoku, Hokkaido, Joetsu and Kyushu Shinkansen, we could not find the locations on the official pages we checked, so ask a crew member on board.
