Background

First held in 2000, MONSTER baSH was created to bring the spirit of large-scale music festivals to the Shikoku region. Its significance lies in its massive economic and cultural impact on Kagawa Prefecture, drawing tens of thousands of visitors annually. Over nearly three decades, it has hosted virtually every major name in the Japanese rock scene, cementing its reputation as a “must-play” event for artists.

The festival is organized by Duke, a prominent promoter in the region, and is known for its smooth operation and fan-friendly layout. The transition from a single-day event to a multi-day powerhouse reflects the explosive growth of Japanese festival culture. Celebrating 27 years in 2026, Monbas continues to innovate while maintaining the grassroots “rock spirit” that makes it a standout on the summer circuit.

What should I bring to an outdoor festival in Kagawa?

August in Kagawa is extremely hot and humid. Essential items include plenty of hydration, sunblock, a hat, comfortable walking shoes, and rain gear, as mountain weather can change quickly.
