Ureru Net Advertising Group is not just setting up a new AI subsidiary on July 15. Its June 30 update also rewrites the substance of the project: the Tokyo Growth-listed group has moved away from the container-style GPU data-centre plan it outlined in March and is now pitching a broader model that combines AI infrastructure with software and SaaS services.
That change removes several of the few hard anchors in the earlier plan. The company said the assumptions it disclosed on March 18, including a container-type facility, an August 2026 start-up, roughly ¥100mn of initial investment and phased spending in the years ending July 2029 and July 2030, no longer apply as previously stated. A new equipment plan is being drafted, while the funding method and final investment amount will be disclosed only once fixed.
The governance set-up has changed as well. Mina Sugimura is now due to serve as representative director of the new unit, BCDC.Ai.GPU Data Center, instead of the previously expected Hiroshi Isogai. Ureru Net said it wanted to separate investors from day-to-day execution, adding that Isogai is expected to take a 49% stake and stay involved on the business side as a shareholder.
| Item | Earlier assumptions | June 30 update |
|---|---|---|
| Business scope | GPU data-centre project | GPU infrastructure plus AI services and SaaS |
| Facility format | Container-type GPU data centre | Priority shifts to deployment inside a large data-centre facility |
| Start-up timing | August 2026 start-up | Revised equipment plan pending; supplement targets completion and start-up next year |
| Initial investment | About ¥100mn | Funding method and investment amount not yet fixed |
| Later investment | Phased capex in the years ending July 2029 and July 2030 | New equipment plan to be disclosed once fixed |
| Leadership | Hiroshi Isogai was expected to be representative director | Mina Sugimura to lead the unit; Isogai is expected to hold 49% and stay involved as a shareholder |
BCDC.Ai is being positioned as more than a server-room build. Ureru Net says the unit will span four pillars: a liquid-immersion-cooled GPU data-centre business, the "isoAi" enterprise AI platform, the "BCDC AI Gateway" API gateway service, and AI-related SaaS including Staff Manager and Concierge Push. Supplemental materials add a tentative first-phase operating model: leasing one section inside a data centre run by a major listed company, at an undisclosed Kanto location, with construction planned this year and completion and start-up targeted next year.
The catch is that the economically important pieces are still open. The company says multiple candidates are under discussion, but no formal contract has been signed. It also says liquid immersion cooling is only a candidate technology at this stage, not a confirmed design choice. For readers tracking Japan's AI build-out, that makes this disclosure less a confirmed data-centre rollout than a strategic reset: more scope, more software, and for now fewer fixed commitments.
