If your trip to Hanabatacho is all locked in but your travel itinerary is looking a little empty, we can give you a helping hand.Not too far from the city center, Kumamoto Castle is one spot you might like to add to your must-see list. If you still have room on that itinerary, Sakura-no-baba Josaien and Toge no Chaya Park will keep you occupied as well.
