The default JP locale is using uni884BuE0100-JP at CID 62673, and uni884B-JP (CID 36610) is not encoded.
Because of a tool bug that displays an incorrect glyph for uni884B-JP (CID 36610) in the above screenshot, this is what the glyph actually looks like.

Sans not affected, although I suggest to use CN glyph for KR.
