IDOL SUMMER JUNGLE 2026 Comes to Odaiba Right After TIF

Article

IDOL SUMMER JUNGLE 2026 runs August 7-9 at Odaiba's R District — landing exactly one week after Tokyo Idol Festival closed out in the same Odaiba area, giving Tokyo back-to-back idol festival weekends this summer.

Dates, Venue, and Schedule

The festival runs three days, August 7-9, 2026, at Odaiba's R District (also referred to as the Aomi/Aoumi area). Gates open at 9 a.m. each day, with performances starting at 10 a.m.

A Large, Genre-Spanning Lineup

Organizers describe a roster of over 300 idol groups across the three days, ranging from established major-label acts like NMB48 to independent and emerging idol collectives — a scale that places it among the larger idol festivals on Japan's summer calendar alongside TIF.

What To Know

Back-to-back major idol festivals in the same Tokyo neighborhood within a week of each other is an unusually dense stretch even for Japan's idol calendar, and international fans planning a Tokyo idol-focused trip will want to know both events are geographically and chronologically close.

Odaiba, a waterfront district in Tokyo, has become a hub for large-scale idol festivals — TIF and IDOL SUMMER JUNGLE both use venues in the same general area (Odaiba Central Square/Aomi for TIF, the R District/Aoumi area for IDOL SUMMER JUNGLE), making it feasible for dedicated fans to attend both within the same two-week window.

What Fans Are Saying

• "Two idol festivals back to back in Odaiba is a dream week for anyone visiting Tokyo this August."
• "300+ groups over three days is a serious lineup, even by TIF standards."
• "Good excuse to just stay in the Odaiba area for two weeks straight."

Original Japanese
