What this is
TREASURE05X is a long-running Nagoya rock festival that has built a loyal following over more than two decades by championing Japanese rock, punk, and alternative acts across multiple stages. The 2026 edition, subtitled 'Rock of Ages', lands at COMTEC PORTBASE in Nagoya's port district on 20 August. Expect a sweaty, high-energy summer festival atmosphere with a lineup drawn almost entirely from the Japanese rock underground and mainstream rock scene.
Who should go
Japanese rock fans — particularly those into visual kei, punk, and alt-rock — will feel most at home here. Casual festival-goers unfamiliar with the Japanese rock scene may find the lineup less accessible than a broader J-pop or international festival.
Good to know
Tickets are typically sold through eplus.jp and pia.jp, both of which accept foreign credit cards; convenience store pickup at Lawson or FamilyMart is the most reliable option for visitors without a Japanese address. COMTEC PORTBASE is a large indoor-outdoor event complex in Nagoya's port district, suited to multi-stage festival formats. August heat at an outdoor or semi-outdoor Nagoya venue is serious — the city regularly records some of Japan's highest summer temperatures, so sun protection and electrolyte drinks are essential. Bag check facilities are usually available at festival-scale events at this venue; confirm on the day as policies vary by event. Arrive at least 30–45 minutes before doors open to clear entry queues smoothly.
