Metaplanet

Metaplanet Inc. was incorporated on June 11, 1999, and has its office in Roppongi, Minato, Tokyo.⁠[1]

In 2024 Metaplanet’s management made a strategic pivot, adopting bitcoin as its core treasury reserve asset and turning the company into a bitcoin treasury company. It is listed on the Tokyo Stock Exchange under code 3350 and trades on OTCQX as MTPLF.⁠[2]

In July 2025 Metaplanet bought another 780 BTC, bringing its holdings to 17,132 BTC. Its updated “555 Million Plan” targets 100,000 BTC by the end of 2026 and 210,000 BTC by 2027, replacing an earlier 2026 target of 21,000 BTC.⁠[3]

In the first quarter of 2026 Metaplanet bought 5,075 BTC for about $405 million, lifting its holdings to 40,177 BTC and making it the third-largest corporate bitcoin holder after Strategy and Twenty One Capital. Its average cost basis was about $104,100 per bitcoin; its shares traded at 302 yen, against a June 2025 peak of 1,930 yen.⁠[4]

In the third quarter of 2026 Metaplanet sold 10,000 BTC and bought 11,000, bringing its holdings to 44,000 BTC as of September 30. It said it would fund future purchases primarily through permanent capital, with 10% to 15% from bonds, loans and preferred shares, and would cap bitcoin-purchase loans at about 10% of the net value of its crypto assets.⁠[5]

Its October 5 notice described the transactions as a sale and reacquisition of bitcoin to demonstrate liquidity.⁠[6]

On October 13, 2026, Metaplanet announced an issue of zero-coupon euro-yen convertible bonds due 2031 and set up a share repurchase program; on October 14 it fixed the bond terms and disclosed the results of share repurchases through ToSTNeT-3.⁠[6]

Metaplanet’s website shows holdings of 44,000 BTC and describes the company as Japan’s largest corporate holder of bitcoin.⁠[7]

Besides its bitcoin treasury operations, Metaplanet owns and operates a hotel in Tokyo and holds the exclusive licence for Bitcoin Magazine in Japan.⁠[2]
