1 Introduction

Over the past year, crypto spot ETFs have been launched in multiple markets, creating a more direct connection between crypto assets and traditional financial systems. According to Japanese media reports, the Financial Services Agency (FSA) plans to amend the Enforcement Ordinance of the Investment Trust and Investment Corporation Act (hereafter “Investment Trust Act”) to include crypto assets within the scope of assets investable by investment trusts. The FSA expects to submit the bill to the Diet as early as 2026. If approved, crypto spot ETF products could be listed and traded in Japan as early as 2028, with assets potentially reaching trillions of yen and prompting brokerages and exchanges to offer supporting services. However, as early as April last year, in the discussion document “Examination of the Regulatory Systems Related to Cryptoassets,” the FSA explicitly stated that ETFs primarily investing in crypto assets could not be established under the current legal framework. Now, with ongoing regulatory discussions, signals of a policy shift are beginning to emerge.

The change in FSA’s stance reflects certain current regulatory trends in Japan. What hurdles remain before Japan can launch crypto spot ETF trading? How will market opportunities and compliance thresholds evolve in tandem? This article will explore the basic mechanisms of crypto spot ETFs and their key differences from futures-based products; analyze the regulatory trends reflected in recent discussion documents and developments; and further examine how policy evolution impacts Japan’s crypto market ecosystem, financial institutions’ business strategies, and investor risk awareness and protection.

2 What is a Crypto Spot ETF: Concepts and Types

2.1 Basic Concepts

ETP (Exchange Traded Product) is a general term for exchange-traded financial products, with ETFs (Exchange Traded Funds) being the most common type operating as funds. In different jurisdictions, products similar to crypto spot ETFs may not be called ETFs, but because their trading experience and investor perception are closer to ETFs, the market generally refers to them as crypto spot ETFs. A crypto spot ETF typically refers to a product whose underlying assets are actual crypto holdings, providing exposure through spot assets. Spot products make trading and holding more convenient but do not eliminate risks such as price volatility, fraud, and market manipulation. When investors shift from self-custody wallets to exchange-traded products, their risk structure changes, but the most immediate variable remains volatility itself.

To understand crypto spot ETFs, view them as a complete chain:

First is the underlying asset and valuation: products usually base their net asset value (NAV) on spot market prices or designated indices. The frequency of NAV calculation, the source of pricing, and how extreme market conditions are handled all affect tracking accuracy and investor experience.

Second is custody: the underlying assets of a crypto spot ETF must be stored within a compliant custody system. Key risk controls include private key management, cold storage ratios, access permissions, and audit arrangements, typically handled by regulated custodians.

Third is creation/redemption and authorized participant (AP) mechanisms: APs arbitrage between primary and secondary markets, helping to narrow premiums/discounts and influence liquidity. During high volatility, premiums/discounts and trading frictions can be amplified.

Fourth is trading costs: trading spreads, market impact costs, and tax treatment differences across markets are important considerations.

2.2 Types: Spot, Futures, and Others

In investment, crypto exchange-traded products are often classified by their primary holding tools: most common are spot-holding ETFs and futures-based ETFs. Spot Bitcoin and Ethereum ETFs usually hold the actual crypto assets to track their prices; futures ETFs hold futures contracts based on the crypto assets.

A spot ETF (or similar product) listed on an exchange is an open-ended fund or exchange-traded product that creates and redeems shares via authorized participants, aiming to track the price of a specific underlying. It primarily holds and safekeeps the actual assets, with NAV calculated based on their fair value. Spot ETFs can hold a single asset (e.g., BTC, ETH) or a basket of multiple assets. Single-asset spot ETFs hold one crypto; multi-asset baskets diversify risk. Spot ETFs are suitable for investors who want exposure to crypto prices within traditional securities accounts without managing wallets or private keys directly, though the underlying price volatility directly affects the product’s NAV.

Futures ETFs use crypto futures contracts as their main holdings. These are publicly traded securities that provide exposure to Bitcoin futures prices. Due to contract expiry and roll-over mechanisms, investors should be aware of potential NAV deviations from rolling futures. Before spot products were approved in the US, ProShares launched a Bitcoin futures ETF.

Besides holding tools, crypto ETFs can be classified by tracking object: single asset or index/basket; by underlying asset class: crypto assets or industry stocks. Leveraged, inverse, and other strategy-based products involve more complex mechanisms, often with daily resets and path dependency, suitable for narrower investor groups.

3 From Rejection to Promotion: Japan’s Changing Attitudes Toward Crypto Asset Regulation

3.1 Market Structure and International Competition

FSA’s recent signals of support for crypto spot ETFs contrast sharply with its previous cautious stance. This near 180° shift is related both to structural changes in Japan’s domestic crypto market and to international competitive pressures.

In Japan, prior crypto regulation mainly focused on payment attributes, including compliance of trading platforms, customer asset management, and price monitoring. Since 2025, Japan has initiated policy and regulatory updates to formally incorporate crypto assets into the mainstream financial system, moving beyond their previous marginal role as payment tools. Legally, the FSA proposed transferring crypto asset regulation from the Payment Services Act (PSA) to the Financial Instruments and Exchange Act (FIEA) last December, treating crypto assets as financial products and aligning their legal status closer to securities. Tax policy is also evolving: Japan released a blueprint for tax reform in late 2024, aiming to reduce crypto asset gains tax from a maximum of 55% to a separate 20%. These policies and potential future adjustments lay a solid foundation for the institutionalization of crypto assets as financial products, creating space for spot ETF market development.

Second, international competition and regulatory benchmarking are key drivers. After the US introduced mainstream crypto futures products, institutional adoption and compliance services rapidly improved. For Japan, this is not only about product supply but also about maintaining competitiveness as a financial hub and attracting capital markets. If Japan remains absent of compliant products long-term, high-quality flows and service capabilities may flow abroad, and domestic financial institutions will lack opportunities to gain experience within a regulated environment.

Third, the FSA’s discussion document does not outright reject crypto spot ETFs but emphasizes their current infeasibility under existing systems; regulatory and market environment changes still offer room for adjustment. The document recognizes the strong investment attributes of crypto assets in practical applications and stresses the need for matching regulatory tools. It proposes two asset classification approaches:

• The first category is financing-related crypto assets, mainly tokens used for project fundraising or utility tokens, with a focus on issuer disclosure obligations, including clear explanations of fund use and project progress.

• The second category is non-funding crypto assets like BTC and ETH, which lack a single issuer, shifting regulatory focus to fairness in trading.

3.2 International Regulatory Paths for Crypto Spot ETFs

Globally, the US, EU, and UK represent three different paths: the US allows mainstream access to spot products with strict rules, disclosures, and market surveillance; the EU emphasizes a unified framework to reduce regulatory arbitrage; the UK restricts high-risk retail products first, then considers expansion under strict disclosure and suitability requirements. Japan may adopt a middle ground—opening access to compliant products while strengthening disclosures, suitability management, and anti-fraud measures to enhance regulation and investor protection.

4 Impact Predictions of Japan’s Crypto Spot ETF Launch

4.1 Current Japanese Market

Japan’s crypto market has expanded significantly in recent years. As of July 2025, there were approximately 13.2 million crypto trading accounts domestically, fewer than securities accounts but still with growth potential. Crypto asset holdings reached about 5 trillion yen in July 2025, then declined to around 4.9 trillion yen in September amid volatility. Overall, the trend remains upward, reflecting increased risk appetite amid inflation and income growth mismatches. Meanwhile, consultations and complaints related to crypto have increased. FSA data shows that in Q4 2024, crypto-related inquiries and complaints totaled 1,304, higher than previous quarters. Regulators face dual pressures: enabling compliant channels and safeguarding investors and financial stability.

4.2 Impact Forecast: Domestic Market and Investors

If crypto spot ETFs are approved in Japan, the most immediate effect would be a shift of crypto investment flows into regulated securities accounts. Funds previously traded directly on platforms might move into ETF products, putting pressure on retail trading volumes and existing assets.

For traditional financial institutions, the potential launch of crypto spot ETFs presents both an opportunity for innovation and a test of compliance and reputation. Given the high volatility of crypto prices, rapid declines after product launch could raise questions about risk disclosure, sales processes, and product suitability. Ongoing regulatory focus on fraud prevention and operational security means internal controls will be a key threshold for institutions to advance related products within a regulated framework.

For investors, especially global asset managers, family offices, and hedge funds seeking Asian allocations, progress on Japan’s crypto spot ETF will be closely watched. Approval would add a compliant entry point in a mature capital market, facilitating asset allocation: products could be bought and sold via securities accounts, with standardized reporting and disclosures, and custody handled by regulated entities. This would make it easier for investors to incorporate crypto exposure into their portfolios within a trusted regulatory environment.
