keisuke,
You don't have biotoping as a concept in HK? Do not forget those! They follow different rules/guidelines than the other scapes. Let me rephrase... the "Dutch" biotope aquascaping style. They are very well developed in this field, more than any other country:
South America (Discus):
South America (Altums):
Lake Tanganyika (Cichlids):
Cameroon, small stream:
...all made in the Netherlands.
And please, tell us about how you view the differing styles in your country. In the United States, we typically split styles into Dutch/Holland and Nature Aquarium/Japanese.
What is the difference between Germany style and Dutch style? I'm also curious to hear the "insiders" description of the Taiwan style. Perhaps we should move this to another thread. We don't want to take over jimjim's topic asking for advice.
