On the evening of May 17, 2026, hololive DEV_IS VTuber Juufuutei Raden went live on YouTube for her 1 million subscriber celebration concert — and the Japanese VTuber community erupted in real-time excitement. Raden is a member of ReGLOSS, a subgroup under hololive DEV_IS (Cover Corp's experimental VTuber label). She built her fanbase through an unusual combination: deep knowledge of fine arts, traditional rakugo storytelling, and a viral moment known as the 'Maitake Dance.' According to Dengeki Online and KAI-YOU, these factors drove her to the 1 million subscriber milestone. When she hit 1 million subscribers in December 2024, Raden announced two things on X: a new personal 3D costume would be produced, and a birthday live would be held on February 4, 2025. Tonight's event is the culmination of that promise — the full 3D costume reveal live. The new costume is a Japanese-Western fusion design featuring a monocle, cane, pocket watch, and a white outfit with red lining. Fans immediately noted how the design reflects Raden's cultural identity, with one viewer writing that it felt like 'East and West coexisting — the very essence of human culture.' The attention to detail in the accessories sparked a wave of enthusiastic close-up commentary on X. Beyond the costume, the live included an in-stream educational segment on the famous Yatsuhashi Makie Raden lacquered inkstone box — a piece of Japanese cultural heritage — which fans dubbed a 'lecture' in keeping with Raden's art-educator persona. A collaboration with the Tokyo National Museum was also announced, a major institutional partnership that surprised even longtime fans. What to watch next: Multiple future activity announcements were made during the live, with plans reportedly extending into early 2027. The Tokyo National Museum collaboration in particular signals a growing bridge between the VTuber world and Japan's traditional cultural institutions — a space Raden has uniquely positioned herself to occupy.
