How fare amounts are determined

The fare amount of domestic fares may change without prior notice.
Fare amount valid on the ticket purchase (issue) date will be applied. Please check the fare amount again at the time of ticket purchase.
If the fare amount is revised after the ticket is purchased, no fare adjustment (charge or refund) will be applied.
For fares that permit reservation change, fare amount may vary depending on the boarding date. If you are changing to a date when new fare amount is effective, the difference between the fare of your ticket and the new boarding date will need to be adjusted (charged or refunded) accordingly.


If you have booked and purchased "One-Way Fare" on April 27 for 28,000 yen (boarding date June 25), then the fare amount changed to 27,000 yen on May 1...

The valid fare amount will be based on the ticket purchase date, so the difference 1,000 yen will not be refunded.
