[Immediate Sell-Out] Official Fan Club for Tatsuo, Talent Affiliated with SeaHorses Mikawa, Reaches Capacity on General Application Start Date! Due to Overwhelming Response, an "Additional Lottery" Will Be Held Starting Wednesday, July 8th!

Thank you for your continued support of the SeaHorses Mikawa.

This is an announcement from Tatsuo, a talent affiliated with the SeaHorses Mikawa.

An Announcement from Tatsuo

Regarding the recruitment of members for the Tatsuo Club for the 2026-27 season... Following the priority member pre-registration and general registration, we have reached our capacity of 370 members. Furthermore, we reached full capacity on the very first day of general registration! Thank you very much for your numerous applications.

I myself am surprised that it filled up so quickly. (The company contracted to manage the Tatsuo Club was a little shaken.)

However, while we are at full capacity, we have also received comments from those who wanted to join but couldn't make it in time. In response to these voices, the Tatsuo Club will be holding an additional lottery for the 2026-27 season!!!

The Tatsuo Club is not just a place where you receive special merchandise (← We put a lot of effort into this every year, so please look forward to it!) There are photo sessions and autograph sessions with Tatsuo, time spent with other members, and before you know it, you might find yourself thinking about Tatsuo a little more... Ultimately, it's a mysterious, dark group where you'll find yourself asking, "What emotion is this?"... it's a fan club. It feels a little suspicious before you join. It still feels a little suspicious after you join. But somehow, the year becomes a little more fun --- That's the Tatsuo Club!

Please seize this opportunity. Let's spend the first year of B.PREMIER together with Tatsuo.

We await your application!!!
