Japan’s Defense Ministry said Friday that Iran used its geographical advantage to “inflict unbearable costs at a relatively low military expense,” effectively closing the Strait of Hormuz by indicating that it had laid naval mines, Kyodo News reported.
The ministry said Japan would strengthen its defense capabilities based on lessons from the US-Iran war, including by using defense equipment also operated by allies and like-minded partners to help ensure rapid supplies from other countries. It also stressed the need to maintain sufficient missile stockpiles and be prepared to quickly increase defense equipment production in an emergency, according to its first report analyzing the Iran war since February.
The US-Israeli war against Iran began on Feb. 28, with attacks targeting military, nuclear and infrastructure sites across the country. Iran responded with missile and drone strikes against Israel and US military facilities across the region.

The Japanese report also said the country should take its own geographical characteristics into account when developing combat strategies, including the fact that it is surrounded by sea. The report noted the US use of AI to accelerate decision-making and operations, citing attacks on around 1,000 targets within 24 hours, while also highlighting the risk of AI making incorrect judgments.
“It is important to establish a process that maximizes the benefits of AI while ensuring appropriate human involvement,” the ministry said. The report comes ahead of a planned revision of Japan’s key security documents by the end of this year.
