I have created JapanProvider.cs that complies with Japanese holiday laws, so could you adopt it?

I created a code that correctly calculates Japanese holidays from 1955 to 2026.
There is also code with verified unit tests.

Hi thanks for your message, sounds very interesting, what about the coming years?

I think this logic can be used for several years unless there is a revision to the holiday law or a major event in the imperial family.
