Canaan has signed an agreement to supply bitcoin mining rigs to a major Japanese utility for a grid-stability research project, marking the country’s first publicly disclosed state-connected mining initiative. The company did not name the utility, but the deal follows earlier reports of Tokyo Electric Power Company (TEPCO) testing small-scale mining operations using surplus renewable energy. In 2024, TEPCO’s subsidiary Agile Energy X piloted bitcoin mining in Gunma and Tochigi prefectures, converting excess solar and wind power into bitcoin during off-peak hours to avoid waste. The Asahi Shimbun reported at the time that the goal was to test whether mining could stabilize grid output without curtailing renewable generation.
Japan’s entry into state-aligned bitcoin mining reflects a growing trend of governments experimenting with mining as part of national energy strategies.
From Experiment to Infrastructure
Canaan said its Avalon A1566HA hydro-cooled servers will be used in the project to stabilize regional grid loads through “controlled overclocking and underclocking,” dynamically adjusting hashrate and voltage based on available energy. The facility, led by the unnamed regional utility, is scheduled to start operations by the end of 2025. According to Matthew Sigel, head of digital assets at VanEck, the deal effectively places Japan among countries where bitcoin mining involves state-linked entities. “All ten of Japan’s regional utilities have partial government ownership,” Sigel said. “This adds Japan to our list of countries mining Bitcoin with government resources,” bringing the global count to 11, excluding the United States. In a later comment on X, Sigel said he could not confirm the partner’s identity but noted that the project still qualifies as a government-aligned mining venture given the ownership structure of Japanese utilities.
Grid Efficiency and Energy Policy
Canaan described the initiative as part of a broader effort to explore energy-efficient, grid-interactive computing. “Utilities can leverage bitcoin mining as a digital load balancer,” CEO Nangeng Zhang said in the company’s release. “We see strong potential for expansion across Asia, North America, and Europe in 2026.” Japan’s interest in grid-integrated mining stems from the challenge of balancing intermittent renewable energy generation. By converting surplus power into digital assets, utilities can maintain steady demand without waste, while potentially creating a new revenue stream during periods of excess capacity. The model mirrors earlier state-linked experiments in Canada, Bhutan, and Oman, where national utilities or sovereign entities have deployed mining operations to monetize stranded or surplus electricity. Japan’s inclusion brings the total number of countries engaged in such activity to 11, according to VanEck’s tracking.
State-linked mining may evolve from energy optimization into a strategic asset class as nations test digital power management using bitcoin infrastructure.
Regulatory Context and Digital Asset Reforms
The project coincides with Japan’s digital-asset regulatory overhaul, which includes proposals to classify cryptocurrencies as financial products under the Financial Instruments and Exchange Act. Lawmakers are also considering a flat 20% capital-gains tax on digital assets to standardize taxation and attract institutional participation. Japan’s renewed interest in blockchain infrastructure follows a decade of cautious regulation after the 2014 Mt. Gox collapse. The latest reforms aim to re-establish Japan as a credible crypto hub while tying digital assets more closely to energy innovation and financial stability. The Canaan partnership suggests that mining could become part of that framework, particularly if it helps stabilize grid operations using renewable energy.
