Changing the language
The Steam store language field I read lists English. Players on the Steam forum in 2021 said a German language had been added and that the game follows the system language.

The sourced answer
I do not have an official language menu diagram, so I will not invent a settings path click by click. The practical reports say the client follows the operating system, and people who wanted English back changed the system or the Steam language. A Japanese localization is not in the store field or in an official post I found. Japanese guides live on community wikis. The Japanese page on this site says the same thing in Japanese.
Russian and Spanish players are in the same boat: community pages, not a store language list I can quote beyond English and the German player report.
FAQ
Is there an official Japanese client?
I did not find one. The Steam language field I read lists English.
How do people switch back to English?
Forum reports say the game follows the system language, so they change that or the Steam language.
