Hello Shiyao, I think your CJK font doesn't support a bold type. Do you can see as a bold font when you type *いろはにほへどちりぬるを* in the org-mode?
If you have the Japanese font which supports a bold type like "Hiragino Maru Gothic ProN", you try below with your own risk: (let ((lst '((#x3000 . #x303f) ; Japanese-style punctuation (#x3040 . #x309f) ; hiragana (#x30a0 . #x30ff) ; katakana (#xff00 . #xffef) ; full-width roman and half-width katakana (#x4e00 . #x9faf) ; cjk unified-ideographs ))) (while lst (set-fontset-font nil (car lst) (font-spec :family "Hiragino Maru Gothic ProN" :size 16)) (setq lst (cdr lst)))) Change "Hiragino Maru Gothic ProN" to the font what you have, and find a good-looking font by trial-and-error. Best. Nonono.
