It always feels awkward when someone believes they have been wronged but in fact they have only misunderstood the grammar or expression because it's their second language. When I was in college, a friend of mine took issue with what they perceived to be a reference to "Jews" in /

[New vlog] The election results (san'insen) and the rise of the far-right, fascist Sanseito are depressing, but should we be surprised?

A new video on how we should spend less time trying to be present everywhere and thus spreading ourselves too thin, and instead put in more time into crafting things that we love creating.

Our upcoming event is about nonbinary identities!
With Prof. Kyoko Takeuchi @kyokotakeuchi.bsky.social, we will talk about what it means to be nonbinary in Japan and how terms like X-gender have evolved.

Coauthoring this research means a thousand times more to me than any title I have won in sport.

In 2013, I made a promise to a young suicidal 13-year-old trans sports girl.

So this is it. A Discord community where we can discuss social issues like queer politics in simple Japanese & simple English! It’s not just language exchange but community-building. Don’t worry about making mistakes or mispronouncing things because that’s 100% OK!
