Bitcoin Japan Completes First Bitcoin (BTC) Treasury Buy: 11.92 BTC at $83,857

Bitcoin Japan's First BTC Purchase

Bitcoin Japan (formerly Hotta Marusho), listed on the Tokyo Stock Exchange Standard market, has completed the first Bitcoin (BTC) purchase of its newly launched corporate treasury program. The group's wholly owned Cayman Islands subsidiary, BTC JPN Ltd., bought 11.9188 BTC on September 28 for a total of $999,479.94 — an average entry of $83,857.43 per coin, equivalent to roughly ¥157.24 million at the disclosed conversion rate of 157.32 yen to the dollar. The acquisition closes out the $1 million first-purchase ceiling the company set when it disclosed the new business on September 18, a cap covering both the purchase price and trading commissions; a separate remittance fee of about ¥85,000 (approximately $540) was booked to wire the funds from Japan. The transaction is detailed in the company's investor-relations disclosure. Until now, the retailer-turned-crypto-company had reported no digital-asset holdings. With this print, Bitcoin Japan joins a widening cohort of Japanese listed companies holding BTC as a long-term balance-sheet asset — a playbook modeled on the strategic reserve approach pioneered by US corporates. Management confirmed additional purchases will follow inside the program's overall budget, and our Bitcoin coverage will track each tranche as it lands.

¥662 Million Program Behind the Buy

The completed buy is step one of a plan financed by a much larger capital raise. On July 16, Bitcoin Japan outlined a financing of approximately ¥9.7 billion through convertible bond-type bonds with share purchase warrants, earmarking ¥662 million of proceeds for Bitcoin investment — the ceiling that all purchases under the treasury business must respect. A board resolution on September 17 formalized two ventures: a Bitcoin treasury operation holding BTC as a financial asset, and a separate Bitcoin-related asset-management business, with the initial $1 million allocation announced the following day. The sequencing is deliberate. As recently as June 3 the company reported zero BTC, having prioritized governance, custody and audit frameworks before deploying capital — a slower, controls-first approach than most corporate adopters. Going forward, the group said the timing, quantity and size of additional purchases will be decided within the ¥662 million cap, weighing market conditions, risk-adjusted opportunities, available funds and group funding needs under its approved investment policy. The move lands as institutional appetite for direct Bitcoin exposure keeps building — a demand shift flagged by Goldman Sachs' incoming CEO back in 2021 — reinforcing the corporate Bitcoin treasury trend now spreading through Tokyo's smaller-cap listings.

Quarterly Mark-to-Market and a Sell Option

How the position is accounted for — and under what conditions it could be unwound — frames the program's risk. Bitcoin Japan said it is still examining the purchase's impact on consolidated results for the fiscal year ending March 2027, and that holdings will be marked to fair value every quarter, with valuation gains and losses flowing through the income statement. That choice means BTC volatility will show up directly in reported earnings, unlike cost-method treatments that keep swings off the P&L, and sharp moves would require prompt disclosure if they materially affect results. The company also drew a clear boundary around the strategy's purpose: it is not targeting maximum BTC holdings, and it may liquidate coins if opportunities with higher expected value creation emerge, citing AI and blockchain as examples. That conditional stance separates the program from pure long-term HODL accumulation models and preserves management optionality. One clarification for readers: this Bitcoin Japan is a distinct company from “Bitcoin Japan KK,” the entity Metaplanet announced it would establish in 2025 — the name overlap has fueled confusion among retail investors. The option to rotate treasury capital into AI mirrors a wider pattern in which AI tailwind for Bitcoin debates increasingly compete for the same balance-sheet dollars.

$84,021 Is the Near-Term Gate

Spot BTC trades at $83,990 as of the latest COINOTAG read, up 1.63% over 24 hours — marginally above Bitcoin Japan's $83,857 entry. Our proprietary 42-indicator composite S/R scoring engine rates the $84,021 resistance at 78/100 on Fibo 0.114 and Ichimoku Tenkan confluence, with the stronger $87,358 ceiling at 82/100 (R3, Donchian Upper, swing high). Below, the $80,834 support scores 78/100 (S3, Fibo 0.236, EMA 20). RSI at 62.23 with a bearish MACD signal inside an uptrend — the same post-golden cross regime recent research flagged — points to near-term consolidation. Positioning is mildly long-skewed: 0.0038% funding, $15.37 billion in open interest, a 1.31 long/short ratio, and the Fear & Greed Index at 73 (Greed). A daily close above $84,021 targets $87,358; losing $80,834 would invalidate the bullish thesis — the cycle framework our Bitcoin Rainbow Chart guide illustrates.
