"Create a photorealistic image featuring the natural landscapes of Japan and China. The scene should include a harmonious blend of majestic mountains, winding rivers, and dense jungles. In the foreground, include a space for an image insertion, such as a blank frame or a natural clearing that clearly indicates where another image can be placed. Ensure the scenery is lush and vibrant, capturing the serene beauty and rich biodiversity of these regions. The overall composition should evoke a sense of tranquility and grandeur, with realistic lighting and textures."
