How to add a url to yahoo.jp?

Thanks for your answer

however I read about the yahoo.jp doesn't have the same search engine than yahoo.com.
Is this true?
My website is for Japanese public and i know many people still using nowadays
But to be honest, yahoo.jp is extremely confuse for me

thanks

If you have already submitted a sitemap or sent crawl requests on Google Search Console, the best way is getting a link from Japanese websites.
