We recently received some inquiry from international guests saying “I can’t enter a date.”
The date format for your country may be mm / dd / yyyy or dd / mm / yyyy.
However, in Japan, date format is yyyy / mm / dd.
yyyy : year（年）
mm : month（月）
dd : day（日）
When entering a date in a lesson reservation request,
In the case of iphone, tap and swipe to select.
In the case of personal computer, display and select the calendar with the mouse.
Thank you for your cooperation.
