List of Japanese anniversaries and memorial days

This is a list of Japanese anniversaries and memorial days or kinenbi (記念日). Many dates have been selected because of a special relationship with the anniversary, but some are the product of Japanese wordplay (語呂合わせ, goroawase).

These are listed by month in date order. Those excluded from the list are as follows:

• Public holidays in Japan such as New Year's Day, National Foundation Day, etc.
• Traditional festivals such as Tanabata and Setsubun
• Personal anniversaries (such as birthdays and wedding anniversaries)
• Anniversaries and memorial days that are only held in a certain locality
• Anniversaries created by companies or organizations to promote a product or event that were not continued or effectively were not commemorated.
