Multiple recent news sources (Japan Times, Jiji Press, Nippon.com), explicitly covering the 40th anniversary of the Plaza Accord, quote Toyoo Gyohten reflecting on the event. The evidence identifies him as a 'former director-general of the Japanese Ministry of Finance's International Finance Bureau' and 'former vice-minister of finance,' which aligns with the description 'Former Financial Diplomat.' Therefore, the statement is fully supported by corroborated evidence.
