Oversized Luggage on the Shinkansen: What to Check First
Do not guess from the bag alone. Check the ticket, train, and baggage-space cue before boarding.
Short Answer
If your bag may be large, check the current train rule and reserved baggage-space option before boarding, not after you reach the platform.
First move
Do this before solving the whole situation
Before buying or boarding, treat the bag as a ticketing question.
