YOKOHAMA☆IDOL SERIES 2026

The YOKOHAMA☆IDOL SERIES is a large-scale outdoor idol music festival held at Yokohama Stadium, one of Japan's most iconic baseball venues and a landmark concert location in the greater Tokyo metropolitan area. The 2026 edition runs across multiple days in late May and features performances from a wide roster of Japanese idol groups and solo artists.

Idol festivals in Japan draw tens of thousands of dedicated fans who follow multiple groups and travel from across the country for major outdoor events. Yokohama Stadium's capacity of over 30,000 and its proximity to central Tokyo and Shibuya make it one of the premier venues for large-format idol events. The series combines headline acts with emerging groups, providing a showcase of the breadth and energy of Japan's idol entertainment industry.
