sumika Release "Umm" Single & Announce 'Flügel Letter' Tour
sumika is gearing up for a major push into late 2026 with the digital release of their NHK-featured single “Umm” and an expansive nationwide tour that will see them hitting Zepp venues across Japan.
The Tokyo-based visual rock outfit has confirmed that “Umm” arrives tomorrow—August 19, 2026—on all major streaming platforms. The track was penned and composed by guitarist Kataoaka Kenta and features actor Minami Kotona on the single artwork. The song is already getting mainstream exposure through NHK’s beloved “Minna no Uta” (Everyone’s Song) program, a significant platform for Japanese artists looking to reach broader audiences beyond their core fanbase.
But the real news is the scale of sumika’s “Flügel Letter” tour run—a winter campaign that kicks off in Osaka this September and cycles through eight cities across the country. Expect packed Zepp dates in major hubs: Osaka, Yokohama, Nagoya, Fukuoka, Sapporo, and Tokyo will all host back-to-back shows, with the run culminating in December with performances at Tokyo Garden Theater.
For Western fans still discovering sumika’s theatrical sound, the band has built a dedicated following through their sophisticated blend of visual rock sensibilities and intricate songwriting. This tour cycle demonstrates their continued momentum in Japan’s underground rock scene.
