JobRainbow.jp is a job-hunting website for those seeking jobs at companies or organizations in Japan that are LGBTQ+ friendly.
I suppose I should note a disclaimer in this post, that I (Travis) do not identify as LGBTQ+, and quite obviously it’s a very diverse community, so I cannot presume to know what features might be most pertinent for you. But I hope that some of those which caught my eye may be of value.
Glancing through the site, two things which popped out at me as potentially rather attractive are buttons for searching for 「LGBTの先輩社員がいる職場」(workplaces where you’ll have LGBT colleagues), and 「自分らしい髪型服装で働く」(workplaces where you can dress, and wear your hair, in a way that fits you).
Scrolling down, we find individual companies rated on their LGBT Friendliness, including ratings for diversity, community, training (研修), and personnel system (人事制度).
The front page of the website indicates that all listed companies have gone through review, such that they’re “only listing excellent LGBT friendly companies” (審査を通過した優良なLGBTフレンドリー企業だけ掲載), and you don’t have to reveal your sexuality to use the site (セクシュアリティは非公開でもOK).
The site allows you to search by region within Japan, industry, and type of position (e.g. full-time, contract work, internship), as well as by which companies or positions offer certain benefits – some particular to LGBT concerns, such as “no difference in male/female uniforms” (男女別の制服無し), and time off for surgery (手術休暇), as well as more general benefits, such as having weekends off, no overtime, overseas business trips, or jobs that don’t require prior experience. The site also allows you to search within several different categories of jobs specifically contributing to or otherwise working with the LGBT community.
Best of luck in your job hunt!
