Spring Japan

Allowed dimensions: 56x36x23 cm · Maximum weight: 7 kg

The context in a few words

A mid-size airline based in Japon, Spring Japan runs a regional network rather than a continent-spanning one. On carry-on rules, the grid is straightforward — no major traps if you respect the published dimensions.

The published format — 56x36x23 cm, 7 kg — matches the broader industry standard. A standard 55×40×20 cabin case clears without issue.

For quick comparison: the IATA reference grid is 56×36×23 cm at 7 kg. Spring Japan sits around 56x36x23 cm, with a weight cap of 7 kg — that benchmark anticipates cabin allowance. Any bag over by more than a centimetre risks rerouting to the hold.

At boarding, checks are usually human and reasonable, but regional aircraft are less forgiving on size. A well-proportioned cabin bag beats an oversized one that ends up gate-checked at the bottom of the jet bridge.

Spring Japan doesn't communicate clearly on the additional personal item. Counter experience favours a small handbag; beyond that, check with the agent or consolidate in the main suitcase to avoid boarding refusal.
