Japan Arranging Leadership-Level Summit with Iran as Trump Hormuz Deadline Looms

Japanese PM Sanae Takaichi told parliament that Tokyo is arranging leadership-level talks with Iran and a separate call with Trump as Trump's latest deadline to bomb Iranian infrastructure approaches. Japan imports over 90% of its crude oil from the Middle East after cutting Russian energy imports following the 2022 Ukraine invasion, making the Hormuz crisis existentially urgent for Tokyo. Unlike Washington, Japan maintains diplomatic relations with Tehran, though a 2019 mediation attempt failed.

Analysis
Japan's 90%+ Middle East oil dependency makes Takaichi's mediation attempt existentially motivated, not merely diplomatic. Tokyo's unique position, maintaining diplomatic relations with Tehran while hosting US military bases, creates a genuine back channel. The 2019 failure under Abe should calibrate expectations, but the stakes are qualitatively different now with Japan-owned tankers actively running the blockade.
