Nobody will deny that Fukuoka is the urbanest region in Kyushu. However, the more sophisticated it gets, the less we can feel local tastes there. It's also true in any countries.
In fact, the closer we get to the canter areas of Fukuoka, the less we can hear the dialects. One of the residents said "You must go to the Chikugo region if you want to hear the dialects."

It means that we are not easy to get what the main stream in Fukuoka is. The more sophisticated it gets, the more diversified it also goes. In other words, the main stream is sparse in the urban fields.
Somehow, in Fukuoka, I found that there are many types of soy sauce. Soy Sauce for Rice with Raw Egg, for yogurt and for bread.

Moreover, there is a
soy sauce tasting bar in Tenjin, Fukuoka Chuo-ku. A male soy-sauce sommelier belongs to the bar, who holds Kyushu Soy Sauce Workshop.
We can conclude that Fukuoka people are pretty particular about soy sauce. If you want to meet unique kinds of soy sauce, it's worth going to Fukuoka once. At the actual stores, there are also unique soy sauce products that don't lie in online shops.
