Be sure to have a full tank of gas, because Nagasaki is worth making a detour for. Located 20 miles from Saikai, it offers some fantastic attractions, such as Glover Garden and Nagasaki Atomic Bomb Museum. Fukuoka, 55 miles away, is another destination that’s worth the journey. Stop by PayPay Dome and Fukuoka Tower, two must-see sights in the area.
