Wednesday Campanella (水曜日のカンパネラ) will hold the “Summer Time Ghost” tour in Europe, from July 27th to August 2nd, with a total of four stops: London, Milan, Paris and Katowice.
The tour will start at the Heaven Club in London; the group will then fly to Milan for the concert at the Legend Club on July 29th (tickets are still available on ticketone). They will be in Paris on July 31st and in Katowice (Poland) on August 2nd at OFF Festival to conclude the tour.

The group is consists of vocalist Utaha, composer Kenmochi Hidefumi and creative director Dir.F. Wednesday Campanella mixes electronic, pop, house, dance and theatre visual in a project that is gaining international attention.
Following the release of their music video for “Edison” in February 2022, the song went viral on social media, amassing 65 million views and over 100 million total streams.
The tour takes its name from the song “Summer Time Ghost” (サマータイムゴースト), released as a digital single on April 4th, 2025. It’s the opening theme of the anime “Kowloon Generic Romance” (九龍ジェネリックロマンス). Blending their signature beatdriven sound with a dreamlike melody, the song instantly immerses listeners into its world. Set on a sweltering midsummer night, it evokes a nostalgic and mysterious atmosphere.
The group was formed in 2013 with KOM_I as the lead vocalist. The members included KOM_I (lead vocalist), Kenmochi Hidefumi (music), and Dir.F (other contributions), although only KOM_I was publicly visible. On September 6th, 2021, KOM_I departed from the group, and Utaha was introduced as the second lead vocalist, marking the commencement of activities under a new structure.
In February 2024, Wednesday Campanella published the theme song for the drama “Konkatsu 1000-bon Knock” (婚活1000本ノック), called “Yuurei to Sakka” (幽霊と作家, Ghost and Writer). It was the first song created by Utaha.
In March they released “Tamamo no mae” (たまものまえ), theme song for the Amazon Original drama “Boku no Itoshii Youkai Girlfriend” (僕の愛しい妖怪ガールフレンド). During the same month, Utaha successfully held her first solo live at Nippon Budokan “METEOR SHOWER”.
In August they published “Charlotte” (シャルロッテ), the commercial song for Lotte Ghana Chocolate.
Since 2023, Utaha has broadened her range of activities beyond music to encompass acting in dramas and films, as well as modeling, establishing herself as a multi-faceted artist.
