Bitcoin Updates: Japan Utilizes Bitcoin Mining to Balance Power Grid with Excess Renewable Energy

Japan has become the world's 11th nation to incorporate

mining into its public infrastructure, signaling a significant change in both energy policy and digital asset strategy. This effort, spearheaded by a leading regional utility in partnership with (NASDAQ:CAN), utilizes excess renewable energy to operate a 4.5-megawatt (MW) mining facility. Scheduled to go live by the end of 2025, the project will use Canaan's hydro-cooled Avalon A1566HA servers, which can automatically adjust hash rates and voltage to help balance the national grid during times of variable energy demand, according to a .

This development builds upon previous trials by Tokyo Electric Power Company (TEPCO), the nation's largest utility, which in 2024 experimented with small-scale Bitcoin mining to make use of surplus solar and wind power, as reported by

. Although TEPCO has not confirmed participation in the current project, the partial government ownership of the unnamed regional utility means the initiative is considered state-affiliated, according to Matthew Sigel, VanEck's head of digital assets. "This marks the first time Bitcoin mining is being integrated into Japan's public infrastructure," he commented.

Canaan's involvement highlights its recent progress in mining technology. The company has introduced its Avalon A16XP air-cooled miner, capable of delivering 300 terahash per second (TH/s) at an efficiency of 12.8 joules per terahash (J/TH), according to

. Part of the A16 series revealed at the Blockchain Life 2025 summit, this miner is designed to help maximize mining profitability as network difficulty increases, according to . Deploying the A16XP in Japan demonstrates Canaan's commitment to aligning energy-efficient mining equipment with institutional and government energy objectives.

Japan's entry into government-supported mining is part of a wider set of digital asset reforms, which include proposals to treat cryptocurrencies as financial products and introduce a 20% capital gains tax, according to

. These reforms are intended to formalize the crypto sector while promoting energy sustainability. By channeling surplus renewable power into Bitcoin mining, Japan aims to enhance grid performance and minimize energy waste—a model Sigel refers to as "clean crypto."

This project also mirrors evolving economic and geopolitical goals. With Prime Minister Sanae Takaichi prioritizing inflation management and fiscal responsibility, the initiative supports efforts to diversify energy sources and attract global investment. Separately, Yokohama-based infrastructure company PTS has launched a Japan-based Bitcoin mining investment product on Republic's platform, giving accredited investors access to professionally managed mining operations under U.S. securities rules, as noted by

.

Nonetheless, critics point out possible inconsistencies in Takaichi's approach, which attempts to balance anti-inflation policies with increased defense budgets and fiscal stimulus. While the mining project is energy-efficient, it may face criticism if it is seen as diverting resources from other economic needs.

As Japan joins nations such as Iran and Russia in state-backed Bitcoin mining, the outcome of this venture could shape international views on the role of crypto in energy management. Canaan CEO Nangeng Zhang highlighted the scalability of the project, with plans to extend similar grid-interactive mining initiatives to Asia, North America, and Europe by 2026. For now, Japan's decision reflects a practical adoption of Bitcoin as both a financial instrument and a means of energy innovation.
