Do we like Takeshi Iwaya?
Our score: 6 out of 10. A steady, mainstream diplomat with no harmful words found, but little sourced good and one denied allegation, so the evidence only goes so far.
Takeshi Iwaya was born in 1957 in Beppu, in Ōita Prefecture, and has been elected to Japan's lower house 11 times, most recently in the February 2026 election. He has been defence minister under Shinzo Abe (2018 to 2019) and foreign minister under Shigeru Ishiba (October 2024 to October 2025). He reportedly left the Aso faction of the Liberal Democratic Party in February 2024.
The stain on his record is a casino one. In January 2020 it was reported that a consultant for the Chinese gambling firm 500.com said he had given about one million yen to each of five lawmakers, Iwaya among them, and Tokyo prosecutors questioned all five. Iwaya denied it flatly, saying “I never received money.” We couldn't find a later outcome for him, so it stays an allegation, not a finding.
On the harm test, nothing nasty turned up. As foreign minister his ministry said Japan opposed Israel's plan to take control of Gaza City, called for a ceasefire and hostage release, and urged action on the humanitarian crisis there. We couldn't find a properly sourced record of what he has said or done on LGBTQ+ rights, trans people, women or the climate, so that part is a gap, not a tick.
The recent news is a China trip. In September 2026 he led about 50 business executives to Beijing as head of a trade-promotion group, and reportedly met Wang Yi for about an hour. Reports say Wang asked for a correction of the prime minister's November 2025 Taiwan remarks, and Iwaya voiced concern about relations; the government called it a private economic mission.
He has form as a China-engager. After his Beijing visit in late 2024 Japan moved to ease visa requirements for Chinese visitors, a decision that drew criticism from some conservatives in his own party. Where you land on that depends on whether you see it as sensible diplomacy or as going soft.
As for the good stuff, we couldn't verify charity or personal kindness, so we won't invent any. What the record does show is a long career in diplomacy and defence with no sourced pattern of harm, plus a ministry that spoke up for Gaza's civilians. That makes him a cautious yes, with a long list of things we couldn't check.
