In Japan the fallen autumn leaves are considered just as beautiful as those on the tree. There are places famous for what is called "ochiba" 「落ち葉」or a place to see the fallen leaves.
The gardeners at this temple have swept the crimson leaves into a dramatic wave pattern, much like the famous dry rock gardens. This "garden," however, will last only a very short time, providing visitors fortunate enough to be there a meditation on beauty and impermanence that is one of Japan's most breathtaking cultural accomplishments.
As a bonus, can you see the rabbit? Look behind the rocks on the left. It wasn't just the people who were enjoying the fallen leaves.
