Will I be taxed if I buy a Nintendo when traveling to Japan?

No. I travel to Japan and purchase the Nintendo in person, and I do not need to pay tax if it does not exceed RMB 5,000. According to the provisions of the "General Administration of Customs Announcement No. 54 of 2010", inbound residents and passengers carry inbound items for personal use acquired overseas. If the total value is within 5,000 yuan (including 5,000 yuan), the customs will release it duty-free. Nintendo does not reach the 5,000 yuan amount.
