Last Boss in Full Bloom: Sachiko Kobayashi Descends on Makuhari Messe on April 25th in a New Giant Costume as 'Hanasaka Baasan,' the Incarnation of Cherry Blossoms

Dwango Co., Ltd. (Headquarters: Chuo-ku, Tokyo; President: Takeshi Natsuno) is pleased to announce that at the massive Niconico event, 'Niconico Chokaigi 2026' (held on April 25-26) at Makuhari Messe, Sachiko Kobayashi will appear as 'Hanasaka Baasan,' the incarnation of cherry blossoms. The performance will take place on Saturday, April 25th, starting at 12:00 PM in the 'Cho Niconico Bon Odori' area, where she will perform live in a new giant costume inspired by cherry blossoms.

Sachiko Kobayashi, known as the 'Last Boss,' has thrilled users with innovative performances and overwhelming live vocals, taking on roles such as a pro wrestler, heavy metal singer, gyaru, and a 'god' of Niconico Chokaigi. For Niconico Chokaigi 2026, themed 'If you move, it will reach,' she takes on a new challenge. Having performed numerous cherry blossom-themed songs like 'Koi Sakura,' 'Senbonzakura,' and 'Sakuragami,' Kobayashi will now embody the cherry blossoms herself as 'Hanasaka Baasan' (The Cherry Blossom-Blooming Old Woman), with cherry blossoms blooming on her head. She will integrate with the 'Cho Neo Yagura' stage in the 'Cho Niconico Bon Odori' booth, descending in a giant costume designed to look like a massive cherry tree. On the day of the event, the excitement from the audience and Niconico comments will be transformed into cherry blossom petals, covering the venue in a blizzard of sakura. Further details, including the song list, will be announced at a later date.

A Comment from Sachiko Kobayashi: 'I've had a lot of fun doing various things with Niconico, but this time is a bit unexpected. I never thought I would become a cherry blossom myself, lol. This time, I'll be waiting for you as 'Hanasaka Baasan,' turning everyone's passion into cherry blossoms. I'm looking forward to seeing all my beloved users at the once-a-year Niconico Chokaigi. Let's make flowers bloom in Makuhari!'
