The evidence from the provided sources overwhelmingly and unanimously confirms the truthfulness of the statement. The Japanese Financial Services Agency (FSA), a primary government source, has published its tax reform requests for fiscal year 2026, which were informed by its working group on crypto assets. This is directly supported and elaborated upon by multiple high-authority sources, including detailed tax reform outlines from professional services firms KPMG and EY. These documents specifically detail proposed updates to the tax treatment of crypto assets, such as new tax rates and carryforward rules. Further corroboration is provided by specialized tax news outlets like ZEIKEN PRESS, reputable research firms like the Nomura Research Institute (NRI), and secondary news reports. There are no contradictions across any of the sources. All evidence consistently indicates that the taxation of crypto assets is a significant component of the discussions and proposals for Japan's FY2026 tax reform. The term "tax reform" encompasses the proposals and outlines, which definitively include these updates.
