The assessment is primarily based on a single, highly authoritative, and relevant primary source. The official notice from the Japanese Ministry of Foreign Affairs (MOFA) explicitly states that consular fees, including passport fees (旅券手数料), will be revised. This directly corroborates the core element of the claim: that a change in Japanese passport fees is officially happening.While the provided summary of the MOFA source does not specify the exact reduction amount (¥7,000) or that it applies specifically to the 10-year passport, the confirmation of a fee revision from the highest possible authority makes the claim very credible. The other sources are either irrelevant to the topic of Japanese passport fees for its citizens (e.g., focusing on visas for foreigners, U.S. travel policies, or university applications) or have zero relevance whatsoever. There is no conflicting evidence presented. Therefore, based on the strong, direct supporting evidence from the Japanese government and the absence of any contradiction, the statement is assessed as likely true with a high degree of confidence.
