Regulator in Tokyo moves to ban insider trading in crypto market

Policy & Regulation·October 17, 2025, 8:11 AM

Japan’s Financial Services Agency (FSA) plans to ban insider trading in the cryptocurrency market, according to an Oct. 15 report in Nikkei, cited by CoinPost. The forthcoming rules would amend the Financial Instruments and Exchange Act to explicitly bar trading based on nonpublic information, with violators subject to administrative fines.

Tightening oversight through the SESC

The FSA intends to hammer out the details through a working group by year’s end and aims to submit a bill amending the securities law during the 2026 ordinary session of the Diet. Under the proposal, the Securities and Exchange Surveillance Commission (SESC) would gain authority to investigate suspected violations and could recommend fines or criminal charges in cases of alleged insider trading.

 

Experts say Japan’s system of self-regulation, led by cryptocurrency exchanges and the Japan Virtual and Crypto Assets Exchange Association (JVCEA), lacks sufficient data monitoring. The government hopes that granting the SESC oversight of crypto transactions will help ensure fairer trading and make the market more attractive to investors.

 

The new rules would target the use of confidential information, such as advance knowledge of a token listing or a major security flaw. Yet applying insider-trading standards to crypto may prove difficult. Many tokens have no clear issuer, making it harder to determine whose information could move markets or who should be held accountable.

 

Crypto investing has surged in Japan, with domestic trading accounts quadrupling in five years. The FSA now aims to update its rules to reflect that digital assets are traded mainly as investments, not as payment instruments.

 

Leadership transition brings policy uncertainty

Japan’s plan to strengthen oversight of cryptocurrencies coincides with a period of political transition. Prime Minister Shigeru Ishiba has announced his intention to step down but remains in office for now. According to CNBC, Sanae Takaichi, newly elected president of the ruling Liberal Democratic Party (LDP), would typically be expected to assume the premiership, but the coalition’s collapse has upended what would otherwise be a routine transition. The parliamentary vote to choose Japan’s next leader, initially slated for Oct. 15, has been postponed to Oct. 21.

 

In the wake of the split, the main opposition Constitutional Democratic Party (CDP) is reportedly seeking Komeito’s support for a joint prime ministerial candidate. Yuichiro Tamaki, leader of the Democratic Party for the People (DPP), is seen as a potential consensus choice. The ruling LDP currently holds 196 seats in the lower house, but a united opposition could command a larger bloc.

 

Tamaki has also drawn attention in crypto circles. About a year ago, he proposed cutting taxes on cryptocurrency gains to 20%, a flat rate similar to that on stock profits, during his campaign against Ishiba. At present, crypto gains in Japan are classified as miscellaneous income and taxed at progressive rates that can exceed 50% when local levies are included.

 

Metaplanet’s Bitcoin strategy tested amid market shifts

Against that backdrop, Metaplanet, often dubbed Japan’s answer to the U.S. firm Strategy for its aggressive Bitcoin (BTC) accumulation, is under pressure as its valuation slips below the value of its crypto holdings. The company’s market-to-BTC net asset value (mNAV) ratio fell to 0.99 on Oct. 14, dropping below 1 for the first time. The metric compares the company’s market value with its BTC holdings, and a reading below 1 means the stock is trading at a discount to its BTC reserves.

 

The decline comes after Metaplanet paused BTC purchases for the past two weeks. As of Oct. 1, the company held 30,823 BTC on its balance sheet.

Chinese City Unveils Plan to Develop Metaverse

Chinese City Unveils Plan to Develop MetaverseThe city of Zhengzhou in China recently announced a set of policy proposals aimed at supporting the growth and development of metaverse companies in the region. These initiatives, introduced by the municipal government, include the establishment of a dedicated fund worth 10 billion yuan ($1.42 billion) to facilitate the advancement of the metaverse industry.Photo by Jéan Béller on UnsplashDraft policy proposalsAccording to the government’s draft which was published on Wednesday, metaverse companies that choose to relocate their headquarters to Zhengzhou will have the opportunity to receive a startup capital investment of up to 200 million yuan ($28.34 million). In addition, these companies will be eligible for various other benefits, such as rent subsidies, to help facilitate their operations.It’s worth noting that the policy extends beyond companies with headquarters in Zhengzhou. Any company engaged in metaverse-related use case development within the city, regardless of their headquarters location, can apply for funding. Projects certified as viable by the municipal government can receive up to 5 million yuan ($710,000) in financial support.While the specific date for fund allocation has not been disclosed yet, the municipal government of Zhengzhou has outlined its long-term vision for metaverse development in the city. It anticipates that metaverse-related industries in Zhengzhou will generate an annual revenue exceeding 200 billion yuan ($28.34 billion) by the end of 2025.Stimulating metaverse developmentThese policies apply to local enterprises operating in two distinct areas. Firstly, research endeavors focused on metaverse-related technologies, such as virtual reality, augmented reality, and brain-computer interfaces, are eligible for support. Secondly, the utilization of metaverse technologies in real-world industries, including education, entertainment, and commerce, can also qualify for funding.In addition to the dedicated fund, the government of Zhengzhou plans to collaborate with other governmental agencies and investment firms to secure an additional 50 billion yuan ($7.08 billion) in funding. This funding will be allocated to support various metaverse-related development projects. Furthermore, the city intends to provide cash rewards to metaverse companies upon their listing on China’s primary stock exchanges, aiming to incentivize growth and market participation.The comprehensive plan encompasses crucial technologies in the metaverse industry, such as blockchain, next-gen computer rendering, human-computer interfaces, and artificial intelligence. Furthermore, it strives to establish a digital asset market leveraging non-fungible token (NFT) technology.Broader metaverse strategyZhengzhou joins a growing list of Chinese cities and provinces that aspire to become leaders in the country’s metaverse development. The metropolis of Shanghai, located in the southeastern region, is actively pursuing its own metaverse aspirations. It predicts that its metaverse industry will achieve annual revenues of 350 billion yuan ($49.6 billion) by the year 2025.Elsewhere in China, there has been plenty of activity relative to Metaverse development. Zhengzhou belongs within Henan Province, and at a provincial level, administrators established a metaverse fund earlier this month. Around the same time-frame, Alibaba Cloud, the cloud division of the Chinese e-commerce giant, partnered with layer one blockchain project Avalanche with a view towards creating a metaverse launchpad.As the metaverse continues to evolve and gain prominence worldwide, it will be intriguing to observe the progress and impact of the policies implemented by Chinese cities like Zhengzhou. The concerted efforts to foster metaverse development reflect a broader global trend of recognizing the significance of virtual environments and their potential to reshape various aspects of society.

Taiko Labs Raises Funding to Build Ethereum-Equivalent zkEVM

Taiko Labs Raises Funding to Build Ethereum-Equivalent zkEVMTaiko Labs, a crypto startup focused on scaling the Ethereum blockchain, has successfully raised a total of $22 million in two funding rounds.According to a blog article published to the startup’s website on Thursday, the first funding round, a $10 million seed raise, was led by Sequoia China and concluded in the third quarter of 2022. The second round, a recent pre-Series A round, raised $12 million and was led by Generative Ventures, according to co-founder Daniel Wang.Photo by cottonbro studio on PexelsBroad investor participationNotable investors in the two rounds include IOSG Ventures, GSR, and GGV Capital, as well as angel investors like Patricio Worthalter, the Founder of the Proof of Attendance Protocol (POAP), Tim Beiko from the Ethereum Foundation, and Anthony Sassano, Co-Founder and COO of the decentralized virtual world, The Sandbox. Taiko Labs has not disclosed its valuation.Scaling EthereumThe primary focus of Taiko Labs is to develop a scaling solution for the Ethereum blockchain that closely adheres to Ethereum’s design and ideology. The company refers to its product as a Type 1 zero-knowledge Ethereum Virtual Machine (zkEVM).Vitalik Buterin, the inventor of Ethereum, emphasized the importance of Type 1 zkEVMs for scaling the Ethereum layer 1 in a blog post. Taiko Labs aims to extend Ethereum’s capabilities by sticking to the Ethereum Virtual Machine (EVM) specification and leveraging its best properties, as explained by Matthew Finestone, co-founder of Taiko Labs.On Wednesday, Taiko Labs released its latest version, its alpha-3 testnet, Grímsvötn, marking a significant milestone on its path to a decentralized and Ethereum-equivalent ZK-EVM.Taiko backstoryThe journey towards Taiko Labs began when Daniel Wang and Matthew Finestone worked together at Loopring Foundation, a trading and payment protocol based on zk-rollup technology. Wang served as the founder and CEO of Loopring Foundation from July 2017 until November 2021, while Finestone worked as the head of business for three years.Wang initially intended to build a decentralized social network but encountered a major obstacle — the lack of infrastructure and scalability. This realization led to the birth of the idea for Taiko Labs.Wang commented on the funding milestone, stating: “We believe that we are now on the cusp of having a truly decentralized Ethereum-equivalent ZK-rollup. This is our core mission at Taiko and we are incredibly proud to partner with leading investors who share our uncompromising vision.”The successful financing rounds will enable Taiko Labs to ensure a successful launch of its mainnet. However, the company is considering raising additional capital, partly to establish an ecosystem investment fund that will attract decentralized applications (dApps) and developers to the ecosystem.In terms of organizational structure, Taiko Labs plans to follow in Ethereum’s footsteps. Wang told The Block: “We are going to quickly convert the organization into a non-profit one. Ideally, we’ll operate very similarly to the Ethereum Foundation.”These successful funding rounds provide a solid foundation for Taiko Labs’ future endeavors, and the company is aiming to make a meaningful impact on the global adoption of blockchain technology with its focus on scaling.

Upbit executive: Establishing crypto regulations hinges on building trust

At the 'Beyond Coin: Brace for Digital Asset Super Cycle' conference held in Seoul on April 30, Lee Hae-bung, Head of Investor Protection Center at Upbit, said that it is significantly important for virtual asset service providers (VASP) to fulfill their responsibilities at a time when the government authority is laying the groundwork for crypto regulations, according to local media TECH M. Upbit is one of the few licensed cryptocurrency exchanges in South Korea. The conference was jointly organized by SEUM Law Firm and local media outlet TECH M.  During his speech at the conference, Lee stated that by adhering to industrial rules and meeting obligations, VASPs can protect not only crypto investors but also themselves. This is how the crypto industry can enhance the value of blockchain and build trust surrounding the cutting-edge technology, he asserted. Photo by Lukas on PexelsShifting paradigm Lee said everything created based on blockchain and ledger technology is now deemed assets and property in the modern world, warranting new regulations. This marks a contrasting shift from the past when only fiat currencies were considered assets and mediums of storage.  In the following sessions, he delivered presentations about cryptocurrency regulations in various countries such as the U.S., Singapore, Hong Kong and several EU member states. During his speech, four moral pillars – legal clarity, responsible innovation, accountability and resilience – were particularly highlighted as ethical requirements for VASPs.  Ten minus one equals zeroLee noted that Korea's crypto industry is currently going through transitional phases, during which the nationwide crypto craze disrupted the market and turned many good-willed investors into victims. The recent Bitcoin rally has lured many young Korean investors in their 20s and 30s to the crypto market, many of whom engaged in reckless investments with borrowed money.  The industry is now at a point where regulations are being laid out for investor protection, however, heading into a sustainable and healthy direction, he added.  "Ten minus one equals zero when it comes to regulating the crypto industry," Lee said, underscoring the significance of completing all the tasks related to establishing regulation in the local crypto space. “Transparency and accountability are the two most important values VASPs must safeguard on their journey to building trust. If VASPs fulfill these obligations, they should be able to gain the trust of users. Otherwise, they must bear liability for the consequences,” he added, citing the European Union’s Market in Crypto Asset (MiCA) Regulation as a model example that values transparency and accountability. The MiCA Regulation is currently being discussed by legislators from EU member states.
