There are things in Japan one cannot explain using english words. What I felt when I was walking through this food market in Kyoto was one of these things.
You can call it loudness but this is very simplistic. Maybe energy or enthusiasm? But these are only a part of it.
Apparently Japanese have a word for it: Genki. It means “energetic, lively and healthy”. Energy, enthusiasm and health are a single concept in Japanese culture.
