Conan-kun does a public relations campaign for the japanese government for gradeschool and high school students to educate children about the ministry’s mission in a pamphlet called “Detective Conan Investigates the Ministry of Foreign Affairs!”

According to animenewsnetwork.com:

In the pamphlet, the father of Conan’s girlfriend is traveling abroad when his luggage and passport gets stolen and he gets caught in an apparent riot with gunshots. The ministry saves the day by issuing a new passport and informing him that “Country A” is just celebrating a festival with firecrackers.

The pamphlet credits list Masaru Ota and Kazuhiro Kubota (staff artists of Conan creator Gosho Aoyama) for the art. The ministry plans to distribute the 5000 copies of the 16-page, half-B5-sized pamphlet to elementary and junior high school students on field trips to the ministry and other occasions. The pamphlet cost the ministry 5 million yen (US$41,000) to produce.
