The statement is strongly supported by multiple, consistent, and credible sources. The primary source is a report from Nikkei, a major Japanese financial newspaper with high authority, which originally broke the story. This report explicitly states that six major asset management firms are planning to develop cryptocurrency investment trusts and names two of them (Nomura and SBI). This core claim is directly and consistently echoed by several other sources, including Yahoo Finance, DL News, and a news report from the crypto exchange Bitget. Furthermore, another high-authority source, the Nikkan Kogyo Shimbun, independently corroborates that one of the named firms, SBI Holdings, is indeed creating a new company to offer products including crypto assets. The provided sources clarify that this is an 'exploration' contingent on regulatory changes from Japan's Financial Services Agency (FSA), which aligns perfectly with the phrasing of the statement. There is no conflicting evidence among the relevant sources. The irrelevant sources (FSA warning page, BlackRock, Vanguard, and PGIM) do not contradict the claim; they simply do not address it. The consistency across multiple high-quality news reports provides a high degree of confidence in the statement's truthfulness.
