Love Fukuoka! That's where my family lives. I didn't get to visit while I was there, but Ainoshima Island -- better known as Cat Island(!) -- is just off of the bay! Tenjin is also a great city to check out while you're in Fukuoka. Delicious tonkatsu ramen in Fukuoka, too. Have a wonderful trip!
Thanks so much Vanessa! I've heard good things about the ramen... I'm sure we'll be slurping a bowl or two (or ten!)
