Overview

Get ready for a massive four-day celebration of the next generation of Japanese indie and rock music with GRAND SLAM 2026. Taking place during the peak of Golden Week, this multi-venue circuit festival transforms Nagoya’s DIAMOND HALL and SPADE BOX into a hub for high-energy performances and breakthrough talent.

The 2026 lineup is a “who’s who” of rising J-Rock and J-POP stars, featuring the infectious energy of Conton Candy, the emotional melodies of moon drop, and the powerful stage presence of groups like yutori and the shes gone. With a “circuit” format that allows fans to move between venues, GRAND SLAM 2026 offers a curated look at the sounds shaping the modern Japanese music scene. Whether you are catching a single day of your favorite band or opting for the “All-Day Pass” to experience the full festival marathon, this is the definitive Golden Week event for rock fans in the Tokai region.

FAQs

What is the U-22 ticket?

U-22 tickets are discounted passes for fans who are 22 years old or younger on the day of the event. To use this ticket, you must bring a valid form of ID that shows your date of birth (such as a Passport). If you forget your ID, you will be required to pay the price difference for a General Admission ticket at the door.

How does the multi-venue entry work?

With your GRAND SLAM wristband (exchanged for your ticket at the entrance), you can move freely between DIAMOND HALL and SPADE BOX. Please note that entry to specific performances is subject to venue capacity; if a venue is full, entry may be restricted until other fans leave.

Are there extra costs at the venues?

Yes. A separate drink fee is required upon entry. This is a mandatory charge in Japanese live houses and is typically paid in cash at the door when you receive your wristband.

How will I receive my “Smart Ticket” for the Nagoya show?

These are digital tickets delivered via a smartphone app. Jasumo handles the Japanese phone number authentication and technical registration required so your ticket is ready to be scanned when you arrive in Nagoya.

What is the policy for children?

Admission fees apply to all children aged 3 and older. Children under 3 may have restricted entry depending on the specific venue safety protocols for loud rock events.
