Left Fukuoka today, stayed in the air conditioned room until check out time (12pm). Walked to the Sumiyoshi Temple and Rakusuien Garden, they are next to each other about 10 minutes from the station. Both are small, but nice places.
Had a good tonkatsu lunch at the Hakata train station. Then went to Starbucks for a drink (matcha frap that I don’t think they have in the US). Walked around the shopping malls in the train station for a bit before heading to the Fukuoka airport a little early (4 hours) before my flight to use the free wifi at the airport.
All in all not a bad trip. Main reason for going got thrown out the window at the last minute but still had to make the best of it. Although I’d suggest never go to Japan (at least most of Japan) in the hot and humid summer months; unless you like 90 deg+ temps and 90%+ humidity!
