Hakata Port Tower & Bayside Place
Bayside Place is a recently renovated dock for Fukuoka, and the international ship port where the ferry and hydrofoil (the Beetle) dock for landing. Here you can take a boat tour around Hakata Bay, go up the 73 meter Hakata Port Tower (and it's actually FREE), or see a massive 3 story indoor aquarium with 1 meter-long fish, giant sea turtles, eels, and baby sharks swimming around inside (and NO, the shark doesn't eat the other fish in the tank). The Hakata Port Tower was erected in 1964 and still offers a great view of
the city and Hakata Bay when the weather is clear.
