The characteristics of "HIRYUJOUUN" are as follows:;

1. Vibrant colors and luxurious presentation: The LED lights illuminating Mount Fuji and the lavish gold flakes resembling falling snow enhance the beauty of the sake. The combination of colors and presentation creates a unique sense of opulence.
2. Enjoyment of seasonal variations: The FADE button on the remote control allows for automatic color changes, enabling the appreciation of the beauty of each season's transformation—spring, summer, autumn, and winter.
3. Enduring radiance and durability: The use of gold flakes, a traditional technique, ensures long-lasting brilliance compared to other metals. It symbolizes the desire for the recipient to shine brightly even in the long run
4. Value as a handcrafted work of art: The bottle itself is a handmade craft by skilled artisans. The meticulous attention to detail in its design adds to its aesthetic appeal, and the glass cap contributes to a sense of unity.
5. Reusable design: Instead of a screw cap, the bottle features a reusable glass cap, allowing for repeated enjoyment of the sake by refilling it multiple times.

Combined, these features make the "HIRYUJOUUN" a unique and beautiful experience.
