In Japan, Jun is famous for his exquisite ramen, which he always prepares with great attention to detail. In the kitchen, his motto is "一 麺 入 魂" (Ichimen-Nyukon). In English you could say that in every bowl and in every single noodle, they put their heart and their soul. In order to not loose sight of this principle, this motto is also written on the back of the work clothes at Ramen Jun.
Germany enjoys a very good reputation in Japan, which is why Master Jun chose the Main metropolis as the starting point for his journey that will lead him and his ramen around the world in the future.
