The Hong Kong government has issued a cautionary alert for residents traveling to Japan following a 7.1-magnitude earthquake that triggered a 'megaquake' advisory from Japanese authorities. This alert is particularly pertinent as it coincides with the peak summer travel season, during which Japan is a favored destination for Hongkongers. The Security Bureau has updated its travel advice but has not escalated the alert level beyond amber, the lowest in a three-tier system. Hongkongers currently in Japan are urged to remain vigilant, monitor safety announcements, and have emergency contact information ready. Additionally, there has been a significant number of hotel cancellations across Japan due to the earthquake threat. Residents needing assistance can reach out to Hong Kong's Immigration Department or the Chinese Embassy in Japan for support.
