In the city

 This curved structure is the roof over the entrance to Hakata Station

 We had lunch in a Thai restaurant on the top floor of the station building the one behind the above curved roof. We were able to sit next to the window and had a marvelous view. The reasons for the glass panels is that there is a door to an outside balcony, but it was closed, probably because of the summer heat.

We walked a couple of hundred meters from the station to Yodobashi Camera, a large electronics store. I wanted to buy a Nexus 7 tablet computer but they were sold out. On the way back I noticed this colorful building. It appeared to be a pachinko parlor.
