May as well share this here too - I'm the head dev on Lolibrary, which is a project archiving information about Japanese alternative fashion. We're doing a big localization push right now, and could really use people who can translate into Japanese and Chinese, as we have a lot of traffic from those parts of the world (but any translation contributions are welcome!)
Knowledge of the fashion isn't necessary - a lot of the stuff to be translated is UI text (password resets, login forms, etc) or general fashion/tailoring terminology (types of fabric, parts of garments). We're [https://hosted.weblate.org/projects/lolibrary](on Weblate here). (and many thanks to the cool folks at @weblate@fosstodon.org for their libre hosting!)
