I won't link to specific recruiters because there are a million, they're easy to find, and everyone likes different ones. Companies that allow remote work in Japan.
- Forkwell - Japanese job search site; tons of jobs with min. salary of 5-6 million or more; filter by programming language
- Hacker News job threads - Lots of remote job opportunities
- Heikin Nenshuu - check salary stats for companies (any public company should be listed); e.g. Cookpad, M3, Cyberagent, Recruit
- Indeed
- JobTalk
- Justa - Like Indeed but more job listings in English
- Vorkers - Japanese Glassdoor basically; to get full access you need to either write a review (which is a huge pain in the ass), or pay for a premium membership; can still get overall rating without signing up though
- Wantedly - Lots of start-up jobs and some from bigger companies; literally just click a button and interested companies will respond
