【Chain Wen】Japan's cryptocurrency tax reform process is progressing more slowly than market expectations. According to the latest disclosures from political sources, the new tax system plan originally scheduled to be implemented in 2027 in conjunction with the revision of the Financial Instruments and Exchange Act may be delayed until January 2028 for official launch.
This news is indeed somewhat surprising. Previously, the industry generally believed that since the parliament is expected to pass the amendment next year, bringing cryptocurrencies under the regulatory framework of the Financial Instruments and Exchange Act, the new tax system would also be promoted accordingly. However, it now appears that the government's priorities have shifted—they are more focused on investor protection and plan to observe the actual situation after the new law is implemented before initiating tax reform. Officially, they say there is "currently a lack of basis to accelerate the process."
For investors, this involves issues related to tax burdens. Japan's current approach is to consider profits from cryptocurrency trading as "miscellaneous income," which must be combined with wages

This decentralized handover model is not uncommon in crypto projects, but HERO shows a different warmth — the project team actively donated $20,000 in creator fees. Even more astonishing: through crowdfunding on the GoFundMe platform, the HERO community has raised over $2.3 million for the victims.
At its peak, HERO's market capitalization once reached $1.7 million. Although this is a small proportion of the total crowdfunding amount, it reflects the cohesion of the Web3 community — using blockchain and virtual assets to participate in real-world charitable causes.
