In Germany, Baumkuchen is made according to strict rules, but in Japan every store sells its own variant of Baumkuchen with its own special ingredients. Typically Japanese, this results in slight regional differences and specialties everywhere. This flexibility is a characteristic of Japanese cuisine, so cultural characteristics and foods from abroad are often incorporated. And of course, in doing so, the Japanese - in all modesty - try to respect the traditional aspects of these foods and drinks, but also to perfect them as far as possible in terms of craftsmanship (compare also
Japanese whisky, which is also made in the traditional Scottish way and is now considered the best in the world).
For Germans, it is interesting to see how traditional German sweets have taken root in the Japanese way of life.
