It's so difficult to tell you the genre of his music. He writes, plays and sing so different types of music, like Nan-Nan(R&B), Mo-E-Wa (hip hop), Damn (pop-rock), Yasashisa(ballade) , Grace, etc, etc. And his lyrics are good, always encourage us, make us so relaxed and accepted, so please check English subtitles in his official MVs and live videos,
Thank you for this readtion❤he is an amazing son writer and pianist at the same time. He has so many variety of songs that you can enjoy. Try Matsuri or NanNan mv!
