Trains in Japan: IC Cards, Reserved Seats, Big Luggage

Japan Travel, Labeled · No. 01 — Trains in Japan: IC Cards, Reserved Seats, Big Luggage

Standing on a platform with a big suitcase, wondering whether your ticket is the right one — or whether the bag is even allowed on this train?

This guide reduces train travel in Japan to three decisions — IC card, reserved or not, and the luggage rule — with the exact numbers the operators publish.

What's inside

• A three-question decision flow that settles which ticket to buy
• Reserved vs. non-reserved seats, and the all-reserved trains where a non-reserved ticket is not enough
• The luggage rules with exact numbers: the 160 cm and 250 cm thresholds, the ¥1,000 fee, and where each rule applies
• 12 platform signs, with readings and what they mean for you
• A worked example: Tokyo to Kyoto with a 175 cm suitcase, step by step
• 5 booking channels compared, and 5 phrases for the station

Rail pass value comparisons in detail; freight and car transport; accessibility booking procedures.

FAQ

Q: My suitcase measures 175 cm in total. Can I just board?

A: On the Tokaido, Sanyo, Kyushu, and Nishi-Kyushu Shinkansen, reserve a seat with oversized baggage area in advance — it costs nothing extra. Boarding without it costs ¥1,000. Other lines have no such reservation system.

Q: Does an IC card cover the Shinkansen?

A: Not the whole trip. The express charge and seat need their own ticket or reservation; the guide's decision flow shows what to buy together.
