Render a Japanese-style landscape scene in a SketchUp style that includes a Koi pond, a tiled-roof gazebo positioned on varied terrain, a fountain, and a bridge. The Koi pond should have clear water with colorful Koi fish swimming. The gazebo, designed in a traditional Japanese style with a tiled roof, should be situated on a slightly elevated terrain, blending seamlessly with the natural surroundings. Add a beautiful, traditional Japanese-style fountain near the pond to enhance the tranquil atmosphere.
