Japan’s debate over sovereign Bitcoin publicity moved from the perimeter to the entrance row this week after JAN3 chief government Samson Mow met in Tokyo with Yuichiro Tamaki, who leads the Democratic Get together for the Folks (DPP), and Sōhei Kamiya, chief of Sanseitō.
Will Japan Set up A Strategic Bitcoin Reserve?
As Mow put it, “We had very productive conferences in Tokyo with Kamiya-san, chief of Sanseito, and Tamaki-san, chief of the DPP. Each leaders already had an amazing understanding of #Bitcoin so our discussions flowed very naturally… I targeted primarily on the restricted window of alternative for a nation-state to build up vital quantities of BTC for a Strategic Bitcoin Reserve. We’ll probably have further conferences later this 12 months.”

The political substance of these conversations tracks long-running parliamentary exercise by each leaders. In Mow’s phrases, “Kamiya-san has raised the concept of Japan holding Bitcoin reserves within the Weight loss plan and known as for tax reform, reflecting his social gathering Sanseito’s sovereignty-first stance. Tamaki-san has proposed reducing capital good points taxes on Bitcoin to twenty% and exempting smaller swaps and funds from taxation, giving Bitcoin fairer remedy in legislation.” He then clarified that “these are actions they’ve finished beforehand within the Weight loss plan.”
JAN3, for its half, framed the agenda in explicitly geopolitical phrases. “JAN3 CEO @Excellion met with Sohei Kamiya, chief of Sanseito, and Yuichiro Tamaki, chief of the Democratic Get together for the Folks (DPP), at their places of work in Tokyo to debate the urgency to create a Strategic Bitcoin Reserve for Japan. Weight loss plan Members perceive the world has modified dramatically with the US SBR already established and the Bitcoin Act on the way in which.”
The reference is to the US’ March 6, 2025 government order establishing a Strategic Bitcoin Reserve (SBR), adopted days later by the introduction of the BITCOIN Act in Congress to codify and scale that framework.
The Tokyo conferences weren’t confined to opposition figures. Mow additionally underscored engagement with gatekeepers within the ruling camp: “It was a pleasure to fulfill Satsuki Katayama at @WebX_Asia the place she delivered a speech on the Bitcoin networking occasion. Katayama-san is a member of Japan’s Home of Councillors, representing the Liberal Democratic Get together (LDP) and in addition chair of the LDP Committee on Finance.”

Katayama certainly chairs the LDP’s Monetary Analysis Fee and has just lately fronted social gathering coverage work touching capital markets, banking supervision and digital-asset points, a sign that Bitcoin coverage sits squarely contained in the LDP’s finance equipment.
Japan’s Political Energy Construction
Understanding how and the place the DPP and Sanseitō sit in Japan’s energy construction is crucial to gauging the chances of near-term coverage change. Within the July 20, 2025 Home of Councillors election, the LDP–Komeito ruling bloc misplaced its upper-house majority, whereas smaller events surged. The DPP gained 17 seats in that contest and now holds 22 seats within the chamber, making it the third-largest pressure after the LDP and the Constitutional Democratic Get together (CDP). Sanseitō captured 14 seats, lifting its whole to fifteen. These tallies translate into actual leverage for each events in an higher home the place the federal government should now assemble issue-by-issue majorities.
Percentages inform the identical story. On the nationwide proportional listing, the DPP took roughly 12.88% of the vote, whereas Sanseitō drew about 12.55%, confirming that each events transformed a broad base of assist into seats. With the LDP–Komeito alliance wanting a majority, that efficiency provides Tamaki’s centrists and Kamiya’s sovereigntists better committee-level bargaining energy over any crypto tax rewrite or extra formidable reserve initiative.
Inside that parliamentary geometry, tax reform is probably the most speedy vector. Tamaki has constantly pushed to interchange at present’s progressive remedy of crypto good points—which might run to the mid-50s % when native levies are included—with a 20% separate tax, and to exempt small-value funds and crypto-to-crypto swaps from recognition, a de minimis regime designed to unlock on a regular basis utilization.
At press time, BTC traded at $113,862.
