AITAMA AI Talent Joins Tokyo Dome OpenDome Accelerator
AIMAX is betting the oshikatsu spending tracked by Nomura Research Institute and the daily-connection gap measured in the Cabinet Office loneliness survey can both be served by an AI character that remembers users between events, a pitch Tokyo Dome's accelerator has now put in front of its second cohort.

AIMAX Inc. says its AI talent AITAMA was selected for the second cohort of OpenDome, an accelerator program run at the enXross DAO coworking space inside Tokyo Dome City. AITAMA is one of eight companies chosen from Japan and overseas, and it has taken part since Monday, October 5, 2026. The company positions the character around conversation memory and personality.
AIMAX, based in Edogawa-ku, Tokyo, develops and operates AITAMA as a companion-type AI talent built on what it calls "Memory and Emotion First": memory of past conversations and responses that express emotion. The company's stated aim is to extend the enjoyment of supporting a character past events and streams into everyday conversation.
AIMAX frames the pitch against two numbers it cites: Nomura Research Institute's estimate of the oshikatsu market at roughly 3.8 trillion yen as of March 2025, and a Cabinet Office survey in which about 40 percent of respondents reported feeling lonely at least occasionally. The company states that AITAMA is not presented as a fix for loneliness or isolation.
