Where SoftBank stands to benefit on Japan’s stablecoin plans

Japan’s ruling party is pushing crypto ETFs and yen stablecoins, and that could turn SoftBank from a crypto-adjacent conglomerate into a central piece of Japan’s on-chain financial infrastructure.

Japan’s ruling Liberal Democratic Party has now moved beyond abstract crypto reform and into something more strategic: a formal proposal for crypto ETFs and yen-backed stablecoins as part of a broader attempt to keep the yen relevant in an increasingly tokenized regional economy.

Reuters reported on June 1 that an LDP policy panel asked the government to promote yen stablecoins for settlement across Asia and build a legal framework for crypto exchange-traded funds.

The stablecoin side is the more consequential part of the proposal. Crypto ETFs can pull traditional investors into the market through regulated wrappers, and in a previous crypto.news piece on spot crypto ETFs in Japan, noted that the expectation was that domestic regulators could approve such products by 2028 if the rules are aligned with market demand and custody requirements.

But stablecoins do something more foundational. They turn currency into software. They make settlement continuous, programmable, and potentially borderless.

That is why yen stablecoins matter far beyond retail crypto trading, and why crypto.news has already tracked this direction in reporting on yen stablecoin reserve rules and on institutional products like JPYSC.

How does SoftBank factor into Japan’s stablecoin plans?

SoftBank sits unusually close to the place where that policy shift could become real. In October 2025, PayPay, SoftBank’s payments arm, acquired a 40% stake in Binance Japan. Yahoo Finance reported that the aim was to fuse crypto access with everyday cashless payments, while a separate crypto.news report on PayPay’s Binance Japan stake noted that users would be able to buy crypto and withdraw proceeds directly via PayPay Money. That matters because PayPay is not a niche product. It is one of the largest mobile payments platforms in Japan, with a user base of more than 70 million according to multiple reports.

The rails are already there

The usual mistake in writing about stablecoins is to focus only on the token issuer. In reality, the bigger fight is over the rails: who controls access, funding, wallet interfaces, merchant reach, compliance, and settlement. PayPay and Binance Japan, taken together, give SoftBank a credible foothold across exactly those layers. Binance Japan users can already move from PayPay Money into crypto and back again, which means SoftBank has already helped create a consumer bridge between conventional digital payments and regulated crypto exposure.

That makes the LDP proposal more interesting. If Japan does legalize crypto ETFs and actively promotes yen stablecoins for regional settlement, those products will need distribution, wallets, payment rails, and interfaces that ordinary people will actually use. SoftBank is already positioned there. It does not need to become a bank or a stablecoin issuer to matter. It simply needs to own enough of the pipes. This logic is already visible in crypto.news reporting on broader financial infrastructure, including Binance’s USD on and off ramps via BPay Global and the slow expansion of regulated rails around exchanges.

This is also why the timing matters. The June 1 Reuters report landed the same day Reuters separately noted that Binance was rolling out trading in U.S. stocks and ETFs, further blurring the line between crypto venues and conventional brokerage platforms. The walls are coming down. Payment apps are becoming financial interfaces, exchanges are becoming multi-asset platforms, and stablecoins are becoming quasi-sovereign infrastructure. SoftBank, through PayPay and Binance Japan, is already embedded in that convergence.

Son’s AI bet sharpens the case

Masayoshi Son’s AI push makes this more than a crypto side bet. It changes the scale of the argument. In late May, SoftBank Group said it would develop and operate 5 gigawatts of AI data center capacity in France, representing investment of up to €75 billion. In SoftBank’s own press release, Son said, “AI is entering a new era, and the countries that build the infrastructure for this transformation will shape the future of technology, industry and society.” That statement is about compute, but it is also about control. Son is not interested in sitting politely at the edge of infrastructure. He wants to own it.

That matters here because programmable money, tokenized assets, and AI-driven financial systems are not separate domains for long. They collapse into one another. The platforms that manage liquidity, route transactions, price risk, and automate treasury functions will depend on cloud capacity, high-throughput networks, compliant payment interfaces, and digital currencies that can move instantly. A future yen stablecoin regime would fit directly into that stack. Crypto.news has already touched adjacent territory in its reporting on how stablecoins are becoming part of the infrastructure conversation, including in coverage of OpenAI’s rise and stablecoins as an AI gateway currency.

Son’s appetite for leverage reinforces the point. The Wall Street Journal reported in February that SoftBank had taken on $27 billion in additional debt over a single quarter as its OpenAI exposure deepened. Bloomberg reporting carried by Yahoo Finance on financing tied to SoftBank’s U.S. data-center expansion showed nearly $1 billion raised for infrastructure linked to its AI buildout, part of a broader flood of riskier debt into that sector. This is not the posture of a company content to clip fees from other people’s platforms. It is the posture of a company trying to position itself at the base layer of whatever comes next.

That is why Son’s AI strategy belongs inside the stablecoin story. His willingness to lever up for AI does not sit alongside Japan’s crypto pivot as some parallel obsession. It turns SoftBank from a passive beneficiary of regulatory change into a company actively building part of the infrastructure stack that yen stablecoins could eventually run through. The combination of payments exposure, exchange access, and AI infrastructure makes SoftBank look less like an opportunistic investor and more like a private-sector candidate to help operationalize Japan’s shift toward tokenized finance.

A monetary story disguised as crypto policy

The deeper point is that this is not really a crypto story at all. It is a monetary sovereignty story disguised as market reform. Reuters’ reporting makes clear that the LDP panel wants yen stablecoins used in Asia because Japan sees the risk of irrelevance if digital settlement becomes dominated by dollar tokens and foreign platforms. That is consistent with the wider global direction. Reuters reported in May that a euro stablecoin project added 25 banks, showing that Europe is also trying to build digital currency infrastructure rather than leaving the field entirely to U.S.-linked issuers. Japan is now signaling the same instinct, only later and more cautiously.

SoftBank is not the state, and it is not a central bank. But if Tokyo follows through, it may not need to be either. It already has scale in mobile payments, an economic claim on a licensed crypto exchange, and a chairman willing to borrow heavily in order to own infrastructure before the market consensus catches up. That is what makes this more than a routine regulatory development. The LDP may be writing rules for crypto ETFs and yen stablecoins, but the market should also be reading those rules as an early map of who gets to sit closest to the rails once Japan decides the yen has to move on-chain.
