Her recent sold-out show at Shibuya’s WWW X was described by one attendee as “a collective therapy session.” Between songs, Matsuzaka speaks softly, almost shyly, thanking the audience not with rehearsed pleasantries but with small, specific observations: “I saw someone in the second row wiping their eyes during the second verse. Thank you for feeling that with me.”

She appeared in this production, also known as The Best and Worst Man: Tsukiji Edition .
