We are aquarium hobbyists. Each of us became attracted to aqua plants and came across the art of aqua-plant layout, which gives us a pleasure to draw out charms of the plants. Then, the hobby has led individual hobbyists to get together in the city of Tokyo. As much as we appreciate aqua plants as a part of nature, we appreciate our meeting as a stream directed by nature. We will continue rowing down the stream, merrily, with passion, toward our goal.
