Fukuoka 3-Day Trip: Airport, Hakata, Tenjin and eSIM
Your Fukuoka weekend starts at the international terminal, where the subway is not right outside arrivals. This guide helps travellers flying from Korea plan that first transfer, choose between Hakata and Tenjin, and fit a relaxed city route into three days and two nights. Spend your full day between Ohori Park and Tenjin, keep departure day close to your luggage, and use Dazaifu as an alternative rather than another compulsory stop. Before flying, check your Korean-market phone, decide when your Japan eSIM should be installed, and set up your Korean number separately for messages and verification.
