Date placeholder is displaying inconsistency in Japanese localization. Japanese localization is set to the common international datestamp of YYYY-MM-DD which is 年年年年/月月/日日 in Japanese.

The datestamp placeholder should show 年年年年/月月/日日, but is showing 年年年年/月月/dd instead.

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"
7. Delete date

Actual results
placeholder is "年年年年/月月/dd"

Expacted results
placeholder is "年年年年/月月/日日"
