Introduction

In the rapidly advancing world of artificial intelligence, the need for robust electrical infrastructure is becoming increasingly critical. As generative AI technology proliferates, the heat produced by high-density servers poses a significant challenge that can't be effectively managed by traditional air-cooling methods. Recognizing this pressing issue, three leading Japanese companies—Nidec Corporation, Daiichi Jitsugyo Co., Ltd., and Kannetsu Corporation—have come together to form an innovative alliance focused on implementing liquid cooling technologies in AI data centers across Japan.

Addressing the Challenges of Cooling Infrastructure

The heat generated by servers is expected to continue on an upward trend, making the transition to liquid cooling an essential component of future data center design. With their collective expertise, the newly formed alliance aims to streamline the implementation process of liquid cooling infrastructure by eliminating complex vendor negotiations, thus ensuring both shorter construction timelines and guaranteed quality in domestic AI data center projects. This “All-Japan” collaboration seeks to create a rapid, efficient, and reliable liquid cooling infrastructure, from design to construction and testing.

Solution Highlights for AI Data Centers

At the upcoming Data Center Japan 2026 exhibition, which will take place in March, the alliance will present its groundbreaking solutions targeting current challenges. Three major strategies have been outlined:

1. One-Stop Liquid Cooling Implementation

The alliance brings together the top runners from each sector to provide an all-encompassing package that encompasses design, procurement, construction, and precise load verification before equipment installation. This approach ensures that clients will benefit from reduced construction time and enhanced quality through seamless cooperation among the three organizations, bypassing any cumbersome intermediary adjustments.

2. Pushing Environmental Performance to the Limits

Given the increasing electricity consumption and water resource usage accompanying the rise of generative AI, this alliance is committed to presenting a next-generation sustainable infrastructure. Their proprietary cooling solutions aim to achieve industry-leading Power Usage Effectiveness (PUE) levels of 1.1 and to minimize water resource consumption, promoting a sustainable future for data centers.

3. Specialized Roles within the Alliance

Each company brings its unique strengths to the table:

• - Nidec Corporation provides high-quality, reliable products essential for server cooling, leveraging their top market share in motor control and manufacturing technology.
• - Daiichi Jitsugyo Co., Ltd. serves as a comprehensive trading company, overseeing global procurement and orchestrating total planning in energy infrastructure.
• - Kannetsu Corporation excels in precise autonomous control of cooling systems and advanced simulation testing using load banks, ensuring that pre-implementation issues are addressed effectively and enhancing the stability of AI server operations.

Aiming for Self-Sufficiency in Japan's AI Infrastructure

Historically, many domestic data center constructions have relied on overseas manufacturers, presenting challenges related to maintenance, customization, and verification in unique environments. This alliance aims to leverage Japan’s intricate engineering capabilities to foster greater independence in the development of AI infrastructure. By combining technologies such as pre-implementation load banks and system control, the alliance aims to prevent operational problems and guarantee continuous server functionality in AI environments.

Key Event Information: Data Center Japan 2026

Mark your calendars for Data Center Japan 2026, which will be held from March 24 to March 25, 2026. The event will take place at the Tokyo Metropolitan Industrial Trade Center in Hamamatsucho. Visitors must register in advance to attend. Additionally, on the first day of the conference, leading experts from the three companies will discuss achievable strategies for reliable infrastructure as demanded by the AI age.
