What this is
KOYABU SONIC (affectionately nicknamed 'Koya Sonic') is a major annual music festival held at Intex Osaka, one of Japan's largest convention and exhibition centers. The festival spans three days over a long weekend in September, making it a flagship late-summer music event in the Kansai region. Organized around a diverse lineup of Japanese artists spanning pop, rock, indie, and comedy-music acts, it draws large crowds from across western Japan. The 2026 edition features 23 confirmed acts in its second lineup wave, including imase, Lucky kilimanjaro, and Football Hour, signaling a broad and eclectic bill.
Who should go
This festival is ideal for fans of contemporary Japanese music who want to discover a wide range of domestic acts in one place over a long weekend. The atmosphere is energetic and festival-casual, attracting a young-to-mid-age Japanese crowd with a strong sense of community around homegrown music culture. Expats and tourists with an interest in J-pop, indie, and alternative Japanese acts will find this a genuinely immersive local experience. Arrive early on your first day to get your bearings across the large Intex Osaka venue and pick up the stage schedule at the entrance.
Good to know
Tickets are typically sold through eplus.jp, pia.jp, and Lawson Ticket — all three platforms accept foreign credit cards, though a Japanese address may be required for physical delivery; opt for convenience store pickup at Lawson to avoid this issue. Intex Osaka is a large exhibition hall complex that transforms into a multi-stage festival space, meaning the experience is largely indoors with air conditioning, which is a significant comfort advantage for a September event in Osaka's heat. The venue is cashless-friendly at many stalls but carrying some yen is advisable for smaller food vendors. Bag check facilities are typically available at the entrance for large bags. The festival runs across multiple days, so a one-day ticket is usually available if you cannot attend all three days — check the official site for day-specific lineups before purchasing.
