Japan’s Defense Minister Sparks Controversy: Is Weapon Export Policy a Game Changer?

Translation result.

On the same day the Japanese government moved to allow arms exports in principle, Defense Minister Shinjiro Koizumi drew criticism for mocking a Communist Party lawmaker who raised the issue in the Diet.

According to the Tokyo Shimbun and other outlets on the 25th, during the House of Councillors’ Foreign and Defense Committee session on the 21st, Communist Party lawmaker Taku Yamazoe questioned revisions to the three principles governing transfers of defense equipment — changes that would effectively permit weapons exports. Something Koizumi said while answering has since provoked debate.

When Yamazoe warned the revisions could open the door to exports of fighter jets, warships and even long-range missiles — systems Japan’s constitution has long prohibited — Koizumi replied, “You mentioned missiles just now. The Communist Party likes missiles; they’ve even called us a ‘missile archipelago.'”

Yamazoe said the remark was unrelated to his question, and Koizumi shot back, “No. It’s related.”

Observers interpreted Koizumi’s “missile archipelago” reference as an allusion to Communist Party lawmaker Tomoko Tamura, who in a House of Representatives budget committee session last November criticized the lack of resident briefings in Kumamoto Prefecture — a planned site for long-range missile deployment — and used the phrase “missile archipelago.”

A video of Koizumi saying “The Communist Party likes missiles” has circulated on social platforms, including X (formerly Twitter), and has racked up more than 2 million views.

The footage shows Foreign Minister Toshimitsu Motegi, seated next to Koizumi, bursting into laughter and covering his mouth at the moment of the remark, while others in the chamber also break into laughter.

The Communist Party held a press conference on the 24th to criticize Koizumi’s tone and conduct during his response.

Yamazoe said Koizumi reacted reflexively to the missile example and jeered at people who oppose arms exports or missile deployments. “This major policy shift to allow weapons exports has raised concerns,” Yamazoe said. “Rather than take responsibility and explain the change, are you trying to ignore dissenting voices?” He urged Koizumi to reflect on his behavior.
