1. Visa (HKSAR passport)
HK readers: Per Japan MOFA public guidance, holders of a Hong Kong SAR passport with the right of abode in Hong Kong are generally visa-exempt for short-term stays (tourism, visiting relatives, business, etc.), commonly up to about 90 days. The exemption does not cover paid work. BNO passport holders with HK residence rights are also covered in related notes. Always re-check MOFA, the Consulate in Hong Kong, and HK Immigration before you fly.
