TOKYO -- Foreign companies are piling into battery energy storage in Japan as they seek to gain an early-mover advantage in a market they expect to grow along with the use of renewable energy.

More than half the total 2.4 gigawatts of capacity up for bid in Japan's first two auctions to procure long term low-carbon power was awarded to companies that are foreign owned or have foreign company shareholdings, a Nikkei Asia analysis found, based on corporate announcements and records of the auction result.
