A quiet koi pond you can visit any time
Virtual Koi Pond is a free, relaxing 3D koi pond simulator that runs in your browser. Koi swim, rest and explore a Japanese water garden on their own. You can feed them, touch the water, and design your own pond, from the layout and stone edge to lanterns, bridges, plants, weather and seasons. No download or account is required.
How to use the pond
- Watch the koi. Tap one to see its name, variety and personality.
- Tap the water for ripples. Press, hold and drag to trail your fingers through it.
- Choose Feed, pick pellets, floating treats, sinking clusters or a feeding circle, then tap the water.
- Open Decorate to change the pond layout and edge, and place more than thirty plants, stones, lanterns, bridges and accents.
- Open Atmosphere for four garden themes, five times of day, five kinds of weather, four seasons and water presets.
- Use Photo to capture a clean picture, or idle ambience mode to leave the pond running on a second screen.
