- SBI Securities and Rakuten Securities — Japan's two largest online brokerages — are independently developing Bitcoin and Ethereum investment trusts accessible through standard brokerage accounts, with no separate crypto exchange account or digital wallet required.
- Japan's Cabinet formally reclassified cryptocurrencies as financial instruments on April 10, 2026, moving them under the Financial Instruments and Exchange Act (FIEA) — pending final National Diet ratification targeting fiscal 2027.
- A proposed tax overhaul would slash Japan's maximum crypto capital gains rate from 55% to a flat 20%, aligning digital assets with listed equities and introducing a three-year loss carry-forward mechanism for the first time.
- Nomura's 2026 Institutional Investor Survey found nearly 80% of Japanese institutional investors plan crypto allocations within the next three years, with 65% citing portfolio diversification as the primary driver — up from 62% in the prior survey.
What Happened
Eleven. That's how many of Japan's 18 largest securities firms told a Nikkei Asia survey they are ready to offer cryptocurrency investment products the moment regulations are finalized. As reported by Google News and covered extensively by Yahoo Finance, the firms expressing willingness include Daiwa Securities, SMBC Nikko Securities, Mizuho Securities, and Mitsubishi UFJ Morgan Stanley Securities. The headline movers, however, are SBI Securities and Rakuten Securities, which are independently developing in-house investment trusts tied to Bitcoin and Ethereum — products customers would access directly through their existing brokerage accounts without needing a separate crypto exchange registration or digital wallet setup.
The regulatory machinery making this possible moved on April 10, 2026, when Japan's Cabinet approved a draft amendment to the Financial Instruments and Exchange Act (FIEA). The amendment formally reclassifies cryptocurrencies — including Bitcoin and Ethereum — as financial products rather than payment tools. Approximately 105 cryptocurrencies currently listed on FSA-registered Japanese exchanges are expected to qualify as "specified crypto assets" under the new framework, with full effect contingent on National Diet ratification and implementation targeting fiscal year 2027.
Simultaneously, Nomura Holdings — Japan's largest investment bank — announced plans to launch a dedicated cryptocurrency exchange in Japan by end-2026 through Laser Digital, its Swiss-based crypto subsidiary, which is currently in pre-consultation talks with Japan's Financial Services Agency (FSA). On the tax side, a reform blueprint endorsed by the ruling Liberal Democratic Party and Japan Innovation Party in December 2025 would cut the maximum capital gains rate on crypto from 55% to a flat 20%, matching listed equities, while introducing a three-year loss carry-forward mechanism — the ability to apply current losses against future taxable gains — that previously did not exist for digital assets in Japan.
Why It Matters for Your Investment Portfolio
Think of Japan's current crypto tax structure as a tollgate so expensive that most professional investors simply avoided the road. A 55% maximum rate — applied because crypto gains were classified as miscellaneous income — effectively priced institutional participation out of scale. Now picture that toll dropping to 20% overnight, while the two firms collectively managing tens of millions of retail brokerage accounts begin packaging Bitcoin and Ethereum inside familiar financial wrappers. That structural shift is what's now in motion.
The mechanics matter well beyond Japan's borders. When SBI Securities and Rakuten Securities launch investment trusts for Bitcoin and Ethereum through their established platforms, they are doing something conceptually parallel to what U.S. spot Bitcoin ETFs accomplished at approval: placing a volatile digital asset inside a conventional brokerage wrapper. Analysts at CoinDesk noted that this architecture puts "ordinary brokerage customers" in reach of Bitcoin and Ethereum exposure "without requiring a separate exchange account or digital wallet," fundamentally lowering the participation barrier at scale. For any retail investor thinking about their own investment portfolio and financial planning, the analogy is a mutual fund: you own a share of the trust's holdings, not the underlying asset directly.

The demand-side data reinforces the scale of what's building. Nomura's 2026 Institutional Investor Survey — which polled 518 investment professionals between December 2025 and January 2026 — found that nearly 80% of Japanese institutional investors plan to allocate to crypto assets within three years, with 60% targeting a 2%–5% portfolio weighting. A full 65% described crypto assets as a vital diversification tool, up three points from 62% in the prior survey. That's the world's third-largest financial market moving in a synchronized direction — regulators, investment banks, retail brokerages, and institutional allocators simultaneously. Investors monitoring the stock market today for rotation signals should note that large institutional mandates don't sit idle when a previously closed asset class structurally opens: they rotate, as Smart Investor Research's recent breakdown of dividend income compression and alternative allocation trends illustrated clearly.
The on-chain trajectory is already shifting ahead of the legislation. Japan's regulatory clarity has historically led to tighter bid-ask spreads and higher liquidity on FSA-registered exchanges. Analysts tracking TVL trajectory (total value locked in Japanese DeFi-adjacent platforms) and net exchange inflows expect both metrics to tighten as institutional allocation mandates crystallize. For anyone managing a personal finance strategy across multiple asset classes, the stock market today context is relevant: tighter liquidity on regulated Japanese crypto venues reduces volatility drag, making the asset class more institutionally tractable — not just more legally accessible.

The AI Angle
Japan's brokerage-integrated crypto model has a fintech dimension that extends beyond regulatory paperwork. As SBI Securities and Rakuten Securities build investment trust infrastructure for Bitcoin and Ethereum, they are integrating blockchain settlement rails into conventional back-office brokerage systems — a technical bridge that requires interoperability between legacy financial infrastructure and on-chain settlement layers. This is precisely the use case that institutional custody platforms like Fireblocks and Copper have built tooling to solve.
For retail investors refining their own financial planning, AI investing tools are already closing the information gap that used to separate institutional desks from individual allocators. Platforms like Messari and Glassnode offer on-chain analytics — tracking holder concentration (how much of Bitcoin's supply is controlled by the top 100 addresses), exchange reserve levels, and net institutional inflows — that were once accessible only to professional quant desks. As Japan's regulatory gate widens, AI investing tools that surface these signals in plain-English dashboards become more actionable for the retail investors who will gain access through SBI and Rakuten's new products. Understanding on-chain data is the difference between reacting to price moves and anticipating structural shifts.
What Should You Do? 3 Action Steps
Japan's new investment trust structure — and the U.S. spot Bitcoin ETF model it resembles — matters for your personal finance calculus. These wrappers carry management fees, counterparty exposure (risk tied to the brokerage's solvency), and tracking error (the gap between the trust's performance and the underlying asset's actual price). Before allocating, verify whether the product holds actual Bitcoin or Ethereum versus derivatives, and compare expense ratios across products. If you prefer direct custody outside a trust structure, a crypto hardware wallet like a Ledger Stax or Trezor puts the private keys — and therefore ownership — entirely in your hands, something a brokerage trust product does not provide.
Japan's proposed 55%-to-20% capital gains cut is jurisdiction-specific, but it signals a global direction: regulators are moving toward treating crypto more like equities for tax purposes. For investors outside Japan, this is the right moment to revisit your own country's rules as part of broader financial planning. In the U.S., crypto is taxed as property — short-term gains under one year hit ordinary income rates, while long-term gains fall into 0%, 15%, or 20% brackets. Japan's proposed loss carry-forward mechanism (applying this year's losses to offset next year's gains) already exists in most equity systems globally; check whether your jurisdiction extends it to digital assets. Getting this right is foundational personal finance before sizing any position.
The risk frame for Japan's institutional crypto wave rests on three sequential dependencies: FIEA ratification by fiscal 2027, the tax reform clearing the National Diet, and Nomura's FSA pre-consultation producing an approved exchange license. Any one of these can delay or derail the timeline. Before treating this news as a confirmed price catalyst, verify on-chain: are long-term holder wallets accumulating? Is exchange reserve declining — a signal that holders are moving assets to cold storage wallet arrangements, historically a bullish supply dynamic? Tools like Glassnode's exchange net position change and CryptoQuant's miner outflow tracker give verifiable, real-time data points. For the conceptual foundation, a crypto investing book like Nathaniel Popper's Digital Gold grounds the narrative history, but current positioning demands current on-chain evidence — not headlines alone.
Frequently Asked Questions
How will Japan's Bitcoin and Ethereum investment trust products actually work for retail investors?
SBI Securities and Rakuten Securities are building in-house investment trusts that give retail customers exposure to Bitcoin and Ethereum directly through their existing brokerage accounts — the same accounts they already use for stocks and bonds. No separate crypto exchange registration, no digital wallet setup, and no private key management is required. Investors would purchase units in the trust much like buying a mutual fund or ETF (exchange-traded fund), with the brokerage managing custody and settlement on the back end. The regulatory framework enabling this — the amended FIEA — is pending National Diet ratification targeting fiscal year 2027. Approximately 105 cryptocurrencies currently listed on FSA-registered exchanges are expected to qualify under the new classification.
Is Japan's crypto capital gains tax reform actually going to pass, and when would it take effect?
Japan's proposed crypto capital gains tax overhaul — cutting the maximum rate from 55% to a flat 20% and introducing a three-year loss carry-forward mechanism — received formal endorsement from the ruling Liberal Democratic Party and Japan Innovation Party in December 2025. However, passage through the National Diet is not guaranteed, and implementation is tied to the broader FIEA amendment timeline targeting fiscal year 2027. Political consensus at the party level exists, but legislative calendars can shift. Investors should treat the reform as a probable rather than certain development and monitor FSA communications and Diet session updates for confirmation.
What does Japan's new crypto regulation mean for global Bitcoin and Ethereum prices in the near term?
Japan represents the world's third-largest financial market by assets under management. Nomura's 2026 Institutional Investor Survey found nearly 80% of Japanese institutional investors plan to allocate to crypto assets within three years, with 60% targeting a 2%–5% portfolio weighting. If institutional flows materialize at scale, the demand-side impact on Bitcoin and Ethereum's liquid supply could be meaningful — particularly if paired with continued accumulation by U.S. and European institutional allocators. That said, global crypto prices are determined by aggregate supply and demand across all jurisdictions, and macro factors like interest rate movements and risk-off sentiment episodes can override regional regulatory tailwinds in any given quarter. This is not a price prediction.
Should I adjust my investment portfolio to add Bitcoin or Ethereum because of Japan's new rules?
Japan's regulatory shift structurally changes how Japanese retail and institutional investors can access Bitcoin and Ethereum, and it signals broader institutional legitimacy for digital assets globally — but it does not change the underlying volatility or risk profile of either asset. For investors evaluating their investment portfolio allocation, the core questions remain: What percentage of total holdings am I prepared to see decline 50% or more in a bear market cycle? Do I understand the difference between holding a brokerage trust product versus the asset directly? Have I reviewed the capital gains tax treatment in my own country? The 2%–5% allocation range that most Japanese institutions are targeting reflects a diversification posture, not a high-conviction concentrated bet.

How does Nomura's planned crypto exchange fit into Japan's broader financial planning and regulatory landscape?
Nomura's plan to launch a cryptocurrency exchange in Japan by end-2026 through its Swiss subsidiary Laser Digital — currently in FSA pre-consultation — signals that Japan's most prestigious investment bank views crypto infrastructure as a viable revenue line, not merely a client accommodation. From a structural financial planning perspective, a Nomura-branded exchange would likely attract corporate treasury mandates and pension fund flows that are legally prohibited from using retail-focused platforms. It also creates competitive pressure on existing FSA-registered exchanges to improve institutional-grade custody, compliance infrastructure, and order-book depth. The broader implication: Japan is building a full institutional stack — brokerage access via SBI and Rakuten, exchange infrastructure via Nomura, and legal clarity via the FIEA amendment — simultaneously rather than sequentially.
