It's been a long time since Goro Inogashira didn't have a long distance business trip. This time he goes to Hakata, Fukuoka prefecture. He first visits his friend's store and then goes to a small udon restaurant and meets the owner.
Just after Goro makes a presentation about Bordeaux, one of the sister cities of Fukuoka. Soon after he will find himself surrounded by the Hakata dialect.
