TOYAMA — At age 82, when most men of his generation are retired, Mikio Honda successfully passed a prefectural test to become a registered door-to-door seller of household medicine kits.

Honda, who hails from the city of Toyama, has been peddling drug kits containing medicines for everyday ailments for more than 50 years. The kits have a relatively low risk of side effects.

Honda traveled periodically to Tochigi and Ibaraki prefectures from his home in Toyama Prefecture as an itinerant salesman, supplying medicine sets to households and collecting money for drugs used.
