The biggest Japanese community in all of Germany lives in the neighborhood of Little Tokyo. Little Tokyo is focussed on the Immermannstraße and the Klosterstraße, which are located in between the main railway station and the city centre. Since its Japanese community the most dense Japanese community in all of Europe, this neighborhood has many Japanese shops, grocery stores and restaurants. Here you can find really authentic Japanese food. We ate some delicious ramen at a restaurant called Takumi (Immermannstraße 28, 40210 Düsseldorf, Deutschland). Also, there is a bakery we like to visit every time we are in Düsseldorf for their melon pan. It is called Bakery Taka (Immermannstraße 36, 40210 Düsseldorf, Deutschland), the owners are very nice, but be aware that usually everything is sold out quite early during the day.
Every year on a saturday in May or June the city of Düsseldorf organizes a “Japan Day”. During that day numerous stalls on various themes around Japan (food, travel, art, …) can be found alongside the Rhine river.
