Japanese PM Takaichi says the Iranian president explained that efforts are being made to resolve the issue while engaging in dialogue with Saudi Arabia as well

Second-hand relaying of diplomatic contacts, with a head of government passing on another leader's account of talks, sits near the soft end of the geopolitical tape; it signals process rather than outcome. The substance here is the Iran-Saudi channel, which since their normalisation has functioned as one of the main de-escalation tracks in the Gulf, and the usual sequence in these episodes is a slow accretion of contact headlines before any verifiable de-escalation step such as shipping behaviour, insurance pricing, or a formal joint statement. Japan's involvement is consistent with form: as a heavy importer of Gulf crude with working ties to Tehran, Tokyo has repeatedly put itself forward as an intermediary, and its premiers have historically carried messages of this kind. For crude the established pattern is that dialogue headlines cap risk premium only at the margin, while the premium itself is set by physical tells: tanker traffic through the Strait of Hormuz, war-risk insurance rates, and any change in Saudi or Iranian rhetoric around production and transit. What distinguishes this from action is the absence of any announced agreement, so the follow-ons are whether Riyadh or Tehran confirm the substance directly and whether freight and insurance markets corroborate easing tensions.
