Japan’s debate over sovereign bitcoin exposure moved to the front row this week after Yang 3 CEO Samson Mo met Tanaka Ojijima in Tokyo, heading Democrats (DPP) and Sansate leader Sohai Kamiya.
Will Japan establish a strategic Bitcoin Reserve?
As Mow said, “We held a very productive meeting in Tokyo with Sanseito leaders, Kamiya-San and DPP leaders. Both leaders already had a good understanding of #bitcoin, so our discussion was flowing very naturally.
The political entities of these conversations track the long-term legislative activities of both leaders. In Mow’s words, “Kamiya-San raises the idea that Japan holds Bitcoin reserves on diets and reflects the attitude of his party’s Sansate sovereign stance in sangsate in search of tax reform. Tamaki proposed lowering Bitcoin tax to 20%, exempting less swaps and exempt Bitcoin payments. He then revealed, “These are activities they have done in the meal before.”
Jan3 framed the agenda for that section in explicitly geopolitical terms. “Jan3 CEO @excellion met with Sanseito leader Sohei Kamiya and Tokyo’s Democratic Party (DPP) leader Sohei Kamiya to discuss the urgency to create a strategic Bitcoin reserve in Japan.
The reference is a reference to a US executive order establishing a strategic Bitcoin Reserve (SBR) on March 6, 2025, and the Bitcoin Act was introduced into Congress a few days later, codified and expanded the framework.
The Tokyo Conference was not limited to opposition parties. Mow also highlighted his involvement with gatekeepers in the dominant camp. “I was happy to meet katsuki katayama on @webx_asia. I gave a speech at a Bitcoin Networking event. Mr. Japan is a member of the Japanese councillors representing the Liberal Democratic Party (LDP) and the chairman of the LDP committee.”
Katayama actually chairs the LDP’s Financial Research Committee, and has recently set a frontline party policy work that touches on issues of capital markets, banking supervision and digital assets.
Japan’s political power structure
Understanding how and where the DPP and Sanseitō sit within the Japanese power structure is essential to measuring the likelihood of short-term policy changes. On July 20, 2025, in the Councillors House election, the LDP-Komeito control block lost a majority of the squad, but a surge in smaller parties. The DPP won 17 seats in the contest and now holds 22 seats in the office, making it the third largest unit after the LDP and the Constitutional Democrats (CDP). Sanseitō won 14 seats, lifting a total of 15 seats. These tallies lead to actual leverage for both Senate parties, where the government must now gather a majority per issue.
Percentages tell the same story. On the national proportional list, the DPP took about 12.88% of the vote, while Sanseitō pulled about 12.55%, confirming that both parties converted a broad support base into seats. LDP – With the Komeito Alliance not at the majority, its performance gives Tamaki centres and Kamiya sovereigns greater committee-level negotiation power over crypto tax rewrites or more ambitious reserve initiatives.
Of the geometry of the parliament, tax reform is the most direct vector. Tamaki consistently promotes today’s progressive treatment of today’s progressive treatment that can run to the mid-50s when local taxes are included, exempting small amounts of payments and crypto-to-crypt swaps from recognition with 20% individual taxes.
At the time of pressing, BTC traded for $113,862.
