There are many koi fish swimming in a pond of water

Envision a serene cascade of an ancient Japanese river. Vivid-colored koi ranging from golds to oranges and reds swim upwards, against the current. The water flows with the traditional "ukiyo-e" stylized wavy lines, while the koi are intricately illustrated with scales and fins that capture the essence of motion. Cherry blossom trees on the riverbanks add a serene atmosphere, embracing the spirit of the "floating world".
