LPS-78314 was supposed to resolve a problem with Japanese date localization so that it displayed YYYY/MM/dd (specifically in Japanese 年年年年/月月/日日), but it looks like this functionality has regressed.

Currently, dates are displayed as 年年年年/月月/dd in any part that requires a date field. This is wrong, because dd should be translated to 日日.

This is apparent in...

• The date field as discussed in LPS-78314 – Birthdate for My Account.
• The Calendar reservation screen
• Dynamic Data List (if we select Inventory)

Steps to Reproduce

1. start Liferay
2. Login Liferay
3. Go to My Account > Account Settings
4. Language select "日本語（日本）"
5. Save changes
6. Select "誕生日" (birthdate)
7. Delete the date

Actual Results
Dates are displayed as 年年年年/月月/dd

Expected Behavior
It is expected that the regression was fixed, and that the date field would be 年年年年/月月/日日
