Three opposition parties in Japan have submitted proposals regarding the country's arms export regulations. The recommendations, which target existing rules on weaponry export, reflect the parties' coordinated stand on defense and national security issues. While the government's response to these proposals remains uncertain, it signals a formation of a united front among the opposition parties in shaping foreign and defense policies.

In Japan, the issue of arms export has always been sensitive due to the nature of its post-World War II pacifistic constitution. The endeavor by the opposition parties to modify the rules indicates a shift in perspective towards a more proactive defense strategy. However, the public sentiment is complex, as Japan has always put high value on maintaining peace and avoiding conflicts.

In contrast, both the US and EU have established comprehensive and detailed regulations regarding arms export. While there are debates on the ethical and strategic implications of arms exports, they are generally viewed as an extension of each country's foreign and security policies rather than an existential issue.
