ASP Kickstarts UK Tour at Japan Matsuri 2025 in London’s Trafalgar Square – Sunday 29 Sep
Alternative idol group ASP‘s latest single BA-BY has been selected by Spotify for its Top Japan Hits by Women editorial playlist. The playlist highlights songs performed by women from the Billboard JAPAN HOT100 chart, a joint project by Billboard and Spotify dedicated to closing the gender gap, that’s accompanied with various articles on the topic.
BA-BY (pronounced ‘Barbie;) sees the group twist the idea of “cuteness” into something both carefree and unhinged, in true ASP style. Its music video marks the debut of newest member iKO MUGENNOKANATA (formerly of BiS) and delivers the chaotic spirit fans expect, with the group’s twins beating each-other senseless AI-style, members’ faces being gleefully squashed by their bandmates, and a finale that sends ASP members diving off a bridge in a real-life bungee jump.
ASP brings a sense of alternative rebellion to the playlist, which features major names such as LiSA, BLACKPINK and CHANMINA. Check it out, and also make sure you don’t miss ASP’s UK Tour dates, all below.
Japanese alternative idol group ASP has announced that it will kick off the group’s debut UK tour with a performance at Japan Matsuri in London on Sunday 21 September 2025. Taking place at Trafalgar Square, Japan Matsuri is the UK’s biggest annual festival of Japanese culture, attracting tens of thousands of people in the heart of the capital.
ASP will perform on the main stage from 3:15pm, and fans will have opportunities to meet the members throughout the day at JPU Records’ booth, which will be located to the left of the stage, in the south east corner of Trafalgar Square.

Previous guests of Japan Matsuri include Britain’s Got Talent finalist Tonikaku, Joji Hirota and the London Taiko Drummers, and Otsu Kagura Troupe, who presented their spectacular ancient Shinto performance of Iwami Kagura.
Showcasing Japanese culture in the UK, Japan Matsuri has attracted a loyal audience of Londoners, the Japanese community and other visitors, families and friends each year since 2009 (at Spitalfields in 2009 & 2010, at County Hall in 2011, and at Trafalgar Square since 2012) and has established itself as a symbol of the long-standing bonds (Kizuna 絆) between Japan and the UK.
The festival takes place from 10am – 8pm and is arranged by volunteers with the support of the Mayor of London, the Greater London Authority, Westminster Council, The Japan Association, the Japanese Chamber of Commerce, the Nippon Club, Japan Society, the Japan Foundation and the Embassy of Japan.
