The Embassy (大使館, Taishikan) is a 2channel board category that had launched on January 12, 2015¹⁾ after a short chat in /liveanarchy/.²⁾ Its boards were designed to be an analogue to 4chan's World4ch which shut down,³⁾ but the message never came across.

First off, the Japanese users have no indication of what the boards are for if the descriptions are all English. I'd suggest adding Japanese text in the board description to explain the intended subject and why you're supposed to use English, or else you've just ended up with /dejima/ clones. Meanwhile, the English users are just not interested in anonymous text boards, but you'll occasionally find one or two lurking around.

• The category was tentatively named “World8ch” at one point.⁴⁾ If posters voted differently, it might've been named “Dejima” (出島) or “Foreigner Refuge” (外人避難所, Gaijin Hinansho) instead.⁵⁾
• Japanese users tend to flock to /vip8/ and /sjis8/ since those two boards actually allow Japanese text.
