Yes, minimalism is embodied in all aspects of Japanese culture. For example: Japanese interior decoration, architectural form and decoration style, food design, etc.

In the final analysis, the reason comes from the "Buddhism" thought taught by ancient China monks to the Japanese.

For example, Japanese "Shi Huai Cuisine", "Tea Ceremony", "Wood Architecture" and "Simple Interior Design".

The same is true of "flower arrangement". Japanese Kazuo often uses "a flower" (a round of flowers) to decorate the room instead of "flowers". Because, in Buddhism, people are encouraged to live a simple and simple life and cherish the gift of nature.
