Hello everyone~! This is Saori from VTuber Republic!

This large-scale and long-running collab is making waves! That popular VTuber is adorably and joyfully welcoming visitors to an amusement center...... A wonderful collaboration is underway~!

ROUND1 is an amusement facility based on the concept of singing, watching, and feeling—all in one! It’s an indoor venue found all across Japan, and while it used to be mainly known for bowling, in recent years it often includes arcades, karaoke, and indoor athletic activities too. It feels like a place where students can go and have a blast on their day off—you can experience all sorts of games and fun in one spot!

This large-scale and long-term collaboration between Yuuki Sakuna-chan and ROUND1, which operates nationwide, is creating quite the buzz! Running through October 2025 and taking place at all ROUND1 locations, the collab offers exclusive merchandise, themed karaoke rooms, and special food and drinks—it's Sakuna-chan everywhere! Since the collaboration lasts quite a while, if you’re visiting Japan during this time, be sure to stop by a ROUND1 and let Sakuna-chan’s cuteness heal your soul~!
