It has been decided that virtual live performance “ARK Allulu World” by virtual singer Hanafu and virtual artist Mori Calliope will be held on Thursday, June 19th, 2025 at the official virtual pavilion of the Osaka Healthcare Pavilion, which will be exhibiting at the 2025 Osaka Kansai Expo, which opened today.
THINKR Co., Ltd. is involved in the production and live production supervision of the pavilion, and is responsible for producing this performance.
Hanafu, the representative virtual singer, and Mori Calliope’s special virtual live performance, a globally active virtual artist, will be held at the “Virtual Osaka Healthcare Pavilion.”
This performance will be held as a scene from the novel-style experience project “Eudaimonia,” produced by Sakuma Yoji, director of the Virtual Osaka Health Care Pavilion.
During the 2025 Osaka and Kansai Expo, Eudaimonia will gradually release media mix content, mainly novels, on the web. The story unfolds depending on the results of the selection and votes made by visitors to the Virtual Osaka Health Care Pavilion. Through this story, the aim is to raise topics such as what happiness is, what fate is, and what free will is, and to give it an opportunity to open the door to thinking about the harmony of humanity, where happiness between individuals and groups overlaps. The music experience at the special virtual live performance will make that question even stronger.
The theme of the “Virtual Osaka Healthcare Pavilion” will be conveyed through a special live performance featuring Hanafu, a representative virtual singer in both name and reality, and Mori Calliope, who is active around the world as a virtual artist.
In addition, THINKR Co., Ltd., which produces Hanafu, and KAMITSUBAKI STUDIO, operated by the company, will be participating in the production of the “Virtual Osaka Healthcare Pavilion” and live performances. In addition to Mr. Sakuma, PIEDPIPER, the general producer of KAMITSUBAKI STUDIO, run by THINKR, is also collaborating with him.
Details such as live streaming times and platform will be released at a later date.
Please come and experience the “future where people and society are harmonious” as the theme of the “Virtual Osaka Healthcare Pavilion” from various angles, including virtual live performances, novel “Eudaimonia” and pavilion.
