SafePlugCheck: the Japan-trip appliance checker
A three-step diagnostic for deciding whether Korean electronic devices will work in Japan and how certain battery-powered items may travel by air.
Field notes
The checker uses three inputs—voltage label, appliance type, and Japanese destination—to produce a compatibility report. Its categories separate heating elements, high-speed motors, chargers, battery devices, and other appliances rather than treating every plug alike. The page also distinguishes Tokyo and Sapporo at 50Hz from Osaka and Fukuoka at 60Hz, and explains why a simple 11-shaped adapter changes plug geometry but not voltage. Korean, English, and Japanese interface switches are visible.
