sorry poor English.
Do travel this year?
If Japanese is understood, a sudden reservation is searchable of the inn that becomes cheap.
If you travel this year......
The 20th and September 23 are national holidays.
It becomes like consecutive holidays because there will be a national holiday in two days on the weekday placed on the weekend.
It is a hazard that it searches for the inn on that day a little.
It is especially dangerous on the 25th of the 22nd of the 19th of the 18th.
(The charge rises, too)
