Japan Joins the Data Center Race: Which Stocks Could Gain

what happened

According to Barron's, while much of the world worries about a possible slowdown in the data center boom, Japan is moving to join it. Analysts say Japanese companies long kept information on their own servers and largely skipped the cloud shift, leaving the country well behind. The International Data Center Authority puts Japan's GDP at one-seventh of the US figure, while its data center use measured in gigawatts is one-seventeenth.

Investors are already making plans. Anthropic and Dell have announced multibillion-dollar Japanese data center projects, and Blackstone outlined a $30 billion Japanese program in June. Prime Minister Sanae Takaichi's government has named AI infrastructure a priority in its 15-year, $2.3 trillion strategic investment plan. The main constraint is electricity rather than sites, with nuclear power now providing less than 10% of the country's supply.

Analysts point to Japanese suppliers that already play key roles in the global supply chain. Mitsubishi Heavy Industries makes turbines for gas-fired power plants, Daihen produces grid transformers, and Fuji Electric and Sumitomo Electric supply equipment and optical cables used in data centers.

why it matters

For markets, this is a story about a long investment cycle rather than an immediate move in share prices. Energy and electrical equipment makers would benefit most if infrastructure spending rises as expected. Concrete figures are expected by year-end, when Takaichi's budget is due to allocate yen amounts to her strategic priorities.

Japanese power equipment and electrical makers: rising data center orders could support their revenue.
