July 4 (Sat) in Tokyo Skytree Town®! 'Nanana's Birthday Party 2026'

Nanana, a Telebana employee at TV Tokyo, will celebrate her 13th birthday on July 7. Once again, surrounded by her best friends, we are excited to host the festive event 'Nanana's Birthday Party 2026~Creating unforgettable memories with Osomatsu-san & Sgt. Keroro at Tokyo Skytree Town®! The mischievous seal Dotzarashi is coming too!~'.

This year features an all-star lineup of guest characters!

From the TV anime 'Osomatsu-san', celebrating its 10th anniversary since broadcast began, comes the eldest of the sextuplets, 'Osomatsu'. From the currently smashing hit film 'New Movie Version☆Sgt. Keroro Revival and Immediate Crisis of Earth's Annihilation!', we welcome 'Sgt. Keroro'. And from 'SEALOOK', whose 2nd season has been confirmed, the playful seal 'Dotzarashi' will rush in to celebrate Nanana!

The event is packed with fun for all ages, including stage performances, character greetings, and a lottery-based high-five session for merchandise purchasers!
