WOODMAN Inc. (Headquarters: Chiyoda-ku, Tokyo; CEO: Shinjiro Ono), a specialist in AI/HPC infrastructure construction, will exhibit at 'Japan IT Week Spring 2026,' one of Japan's largest IT exhibitions, held at Tokyo Big Sight from April 8 (Wed) to 10 (Fri), 2026.
Booth Number: W4-45
At this exhibition, WOODMAN will publicly unveil for the first time actual units of the 'MICHIBIKI DC Panel Type'—developed in collaboration with Michibiki Inc.—and the '4U Liquid Immersion Cooling Solution' featuring a native liquid immersion design. These represent next-generation infrastructure options addressing the increasing density and heat generation in AI and GPU server environments. Visitors can experience the actual scale and innovative design at the booth, which cannot be fully conveyed through drawings or documents alone.
Featured Exhibits (First Public Unveiling/Physical Display):
[Physical Display] MICHIBIKI DC Panel Type (Collaborative Solution with Michibiki Inc.)
A groundbreaking solution combining WOODMAN's global data center supply chain with Michibiki's modular data center design philosophy. It rapidly transforms vacant spaces in existing buildings, such as logistics centers or factories, into data hubs.
Features: Utilizes 1m x 3m panel modules, allowing for implementation as 'equipment' rather than a 'building,' thus bypassing building permit requirements. It realizes immediate value from idle assets with low risk and features high BCP performance through seismic isolation structures.
[Physical Display] Native 4U Liquid Immersion Cooling Solution
A first-of-its-kind physical debut for a native immersion-designed solution that fundamentally rethinks air-cooled structures to achieve ultra-high density implementation and overwhelming cooling efficiency for AI and LLM applications. The immersion tank on display boasts high cooling capacity in a space-saving format.
Tank Specifications (MLC06104FI):
- Cooling Capacity: 8kW
- Dimensions (LxWxH): 766mm x 820mm x 1120mm
- Available IT Equipment Space: 4U
- Rated IT Equipment Power: 6kW
- Installation: Vertical
- Weight: Net 328kg / Operating 475kg
- Environment: -5 to 45°C, 10% to 90% RH
Benefits: Dramatically improves PUE and reduces power consumption. The vibration-free and dust-proof environment also lowers failure rates.
Liquid Immersion Cooling S6485i 4U-Server Node:
- Features: Supports dual 4th/5th Gen Intel Xeon Scalable Processors and up to 8 FHFL double-width PCIe 5.0 AI accelerators. Optimized for liquid immersion solutions. WOODMAN provides product warranty and repair support.
Other Data Center Construction Solutions (Models/Panels):
- WOODMAN QuickBuild DC™ (Scale Model Display): A high-speed, 2MW containerized water-cooled DC solution with a delivery target as short as 7 months from order.
- MICHIBIKI DC Module Type: High-density, seismic-isolated modular DC meeting strict Japanese building standards, scalable from 1MW to 10MW.
Recommended for:
- Companies considering infrastructure for AI/HPC.
- Systems managers concerned with cooling for high-density GPU environments.
- Those looking to utilize idle space in existing facilities.
- Data center/infrastructure operators and local governments.

FAQ
What does it mean by 'no building permit required'?
Since it is classified as 'machinery and equipment' rather than a 'building,' it can bypass the lengthy building permit applications and major civil engineering work, allowing for rapid deployment inside existing warehouses or factories.
What are the main benefits of liquid immersion cooling?
It dramatically improves PUE (Power Usage Effectiveness) compared to traditional air cooling, significantly reducing cooling energy. Immersing equipment also eliminates vibration and dust, lowering failure rates and enabling ultra-high density implementations.
Where can I see these solutions in person?
The actual machines will be on display at the WOODMAN booth (W4-45) during 'Japan IT Week Spring 2026' at Tokyo Big Sight from April 8 to 10, 2026.
