 The name Suiyōbi no Campanella is in reference to their usual rehearsal meeting day of "Suiyōbi" (Wednesday).Its mixing of Kanji, Katakana and Hiragana was primarily to appeal to the group's collective ego.For their international debut at the SXSW festival in Austin, they adopted the English moniker online, "Wednesday Campanella", which they continued to use in San Francisco for their 2016 J-Pop Summit show and in 2017, at Le Magnifique Society Festival show in Reims, France.
