Raizan trail is certainly much beautiful than Homanzan, though weather is cloudy. Sadly we didn't have enough time to cross to Iharayama peak as well and do a return loop.
Going to Canal City Hakata, they have a musical water fountain and light show going on occasionally.
The best part of the garden is Koi watching, which can only be done outside of the tea room (do we didn't go for the tea). Entrance is 200 yen.
