Supporting the foundation of SANNINSHOW’s activities and driving sustainable growth

GANYMEDE Inc. (Headquarters: Minato-ku, Tokyo; CEO: Daisuke Nishihara) is pleased to announce that it has entered into a management agreement with the gaming creator group SANNINSHOW.

About SANNINSHOW

Formed in 2011, SANNINSHOW is a three-member gaming creator group consisting of Donpisha, Pechanko, and Tettou. Known for their natural chemistry and distinctive atmosphere, the group has produced a wide variety of game commentary content over the years.

Primarily active on YouTube, SANNINSHOW has amassed over 800,000 subscribers and achieved more than 1 billion total views. With a play style unconstrained by genre and approachable, engaging conversation, the group has built a broad and loyal audience. Today, SANNINSHOW holds a firmly established position as one of the most representative figures in Japan’s game commentary culture.

Background of the Management Agreement

Since its formation in 2011, SANNINSHOW has continuously delivered diverse gaming content on YouTube, earning long-standing support from a wide fan base. In addition to daily production activities such as live streaming, recording, and editing, the group has independently handled a wide range of responsibilities—including event appearances, negotiations with corporate partners for video projects, organizing self-produced events, and developing merchandise.

As their activities expanded, SANNINSHOW began receiving an increasing number of new requests and opportunities, both as a group and as individual members. In order to move on to the next stage while preserving the creative style they have built themselves, it became essential to strengthen their operational foundation through professional management support.

GANYMEDE Inc. believes that the planning capabilities and management structure cultivated through the operation of its professional esports team ZETA DIVISION can effectively support SANNINSHOW—particularly in areas such as corporate negotiations and project coordination.

Furthermore, by leveraging insights gained through organizing various events and content initiatives, GANYMEDE is confident it can create new opportunities to share SANNINSHOW’s unique appeal with an even broader audience. With this background, GANYMEDE has decided to enter into a management agreement with SANNINSHOW and work together to further advance their activities.

Future Outlook

Through this partnership, GANYMEDE will respect SANNINSHOW’s distinctive style while combining it with the company’s established networks in the esports and streamer space to explore new possibilities together.

While continuing to focus on their core activities—game commentary and live streaming as they always have—SANNINSHOW aims to develop new projects and content through interactions with professional players and streamers who play the same titles.

Looking ahead to the group’s 15th anniversary in 2026, SANNINSHOW is also considering commemorative events and collaborative merchandise initiatives.

By applying GANYMEDE’s expertise in event planning and operations to bring these ideas to life, the company believes it can deliver new forms of entertainment unique to SANNINSHOW to an even wider fan base.

Comments from SANNINSHOW Members

From Donpisha

“We’re not exactly joining a team, but being able to get closer to the people we support, watch regularly, and work with honestly makes us very happy. We’re not exactly young anymore, so while continuing our own activities, we’d also like to take on more of a supporting role when possible. We’d be glad if working together leads to something fun.”

From Pechanko

“We plan to keep everything about SANNINSHOW as it is, while also exploring things that can only be done together with GANYMEDE. Our goal is to entertain everyone who watches us even more than before.”

From Tettou

“The average age of SANNINSHOW is 41.33. At this point, we’ve found ourselves being supported by some very capable adults. Our usual activities won’t change much, but we may be able to do more new things. We’d be happy if you continue to enjoy watching us old guys.”
