Regarding the Sponsorship Agreement

Hello! I am “Botamaru-Yuki,” a VTuber passionate about Japanese swords. I share information about cultural properties, including Japanese swords, on platforms such as YouTube and X (formerly Twitter). I first connected with the Gunjo Foundation when I covered the tachi sword “Seigaiha,” which they manage, and I am now honoured to receive their support. With their support from the Gunjo Foundation, I will strive to contribute even more to the preservation of cultural properties. Thank you for your continued support.
