The Invisible Orientation is now available in a Japanese translation.
This is a translation of the original material and is still a Western conception of the culture and concepts of asexuality. Its content has not been localized.
But it is available in bookstores and through its Japanese Amazon page.
My sister, whose husband is from Japan and has relatives there, recently found the book in a bookstore and bought a copy. Here it is in the wild, with photos from her Instagram. 🙂
