Bakkt Opco Holdings LLC Takes 28.28% Stake in Bitcoin Japan (8105) | Large Shareholding Report

A large shareholding report (EDINET filing) reveals that Bakkt Opco Holdings LLC has raised its stake in Bitcoin Japan (8105) to 28.28%. The filer is a US technology company operating the cryptocurrency exchange Bakkt. This ownership stake represents nearly one-third of Bitcoin Japan's outstanding shares, positioning the filer as a major shareholder with substantial control over the company.

The 28.28% stake appears to represent a new or significantly resumed holding, as no prior disclosure by the same filer was detected within the previous 400 days. The estimated acquisition amount totals ¥5.56 billion, with the report filed on August 12, 2025. This aggressive acquisition signals a potential shift in Bakkt's investment strategy toward the Japanese cryptocurrency market.

*Speculation: This substantial investment by a US-based cryptocurrency exchange operator in a Japanese peer suggests a possible strategic move to expand business operations or strengthen partnerships within the Japanese market.
