JAPAN PERSPECTIVE

Tokyo doesn't merely observe — Japan positions itself as mediator. A Mainichi Shimbun editorial, repeated by English-language press, argues Japan should lead mediation toward US-Iran ceasefire. The argument rests on specific diplomatic capital: Japan is the only G7 country maintaining continuous relations with Iran, and former Prime Minister Abe attempted mediation in 2019 during his Tehran visit — first by a Japanese leader in 41 years. This proposal is not disinterested. Japan imports 90% of its oil from the Middle East and strikes on Kharg Island directly threaten its supply. Physical oil at $150 is existential urgency for an economy dependent on imports for 88% of primary energy and whose strategic reserves would last only four to five months in complete blockade. IRGC strikes on Jubail petrochemical complex add another anxiety layer: if Saudi Arabia — Japan's top supplier with approximately 1.2 million barrels daily — is now in the fire zone, Japanese energy diversification is a mirage. Tokyo invested massively in nuclear and LNG after Fukushima, but oil remains irreplaceable for transport and petrochemicals. Trump's ultimatum is read not as moral question but as countdown toward supply crisis. If the deadline expires without agreement and strikes intensify, Japan will be among the first countries suffering consequences — hence the urgency of mediation.
