Shinkansen oversized baggage rules

A suitcase of 160 cm or less, measured as the total of three sides, needs no reservation on the Tokaido and Sanyo Shinkansen. A bag from 161 to 250 cm needs a reserved seat with a baggage area. A bag over 250 cm cannot come on board ¹.

What are the size limits?

JR Central sets three bands for the Shinkansen, the bullet train between major cities.

Total of three sides	Rule
160 cm or less.	No reservation. Keep it at your feet, overhead or in the deck area.
161 to 250 cm.	Reserve a seat with an oversized baggage area.
Over 250 cm.	Not allowed on board.

The reserved seat costs the same as a regular reserved seat ¹.

Where do large bags go?

The seats with an oversized baggage area are in the last row of some cars ². That is why you need the reservation: the space sits behind those seats.

Choose that seat when you book, and tell everyone in the group which car number to use. Read reserved versus unreserved seats and luggage for the seat rules.

What if you forget to reserve?

JR Central says bringing oversized baggage without a reservation incurs a carry-on fee of 1,000 yen including tax. You must also store it where the conductor directs ². At the Bank Negara selling rate of RM 2.603 per 100 yen on 19 October 2026, that is about RM 26 ^{2 3}.

The fee is small, but the search for a place is stressful with elders. Reserve in advance.

Do the rules cover every line?

The reservation rule applies to the Tokaido, Sanyo, Kyushu and Nishi Kyushu Shinkansen. On conventional lines, no reservation is needed for oversized baggage ¹. Other Shinkansen lines have their own rules, so we check the operator for your route.

Is forwarding easier than carrying?

Often yes, for groups. Most major hotels can arrange luggage delivery between hotels. Delivery limits include items up to 160 cm in total size and about 25 to 30 kg, and valuables and fragile items are not accepted ⁴. Station coin lockers cost between 300 and 600 yen ⁴.

Takkyubin is a luggage delivery service between hotels or airports. Read sending luggage between hotels and coin lockers versus station storage.

How do we plan it for a group?

We handle luggage as part of the route.

1. We collect each bag’s size and weight before booking.
2. We reserve seats with an oversized baggage area where a bag needs one.
3. We forward heavy or bulky bags to the next hotel when that is simpler.
4. Everyone keeps a small day bag for the train.

For elders, read Japan with grandparents, fewer luggage transfers and packing light for multi-city Japan.

What should Malaysian travellers remember?

Measure your suitcases at home, adding length, width and depth. Tropical packers add winter coats on the way back, so allow space. Send us your bag sizes, and we check the rules for each train.
