The word "gari" means hunting, and the word for maple leaves is "momiji", which also means small child. So, in a way, people are chasing after these little children as they run through the mountains.

The best time to see koyo in Japan is usually from mid-November to early December. During this time, the Japanese government releases an annual Koyo Forecast Map that shows where the best spots are. It's like a treasure map for leaf peepers!

In addition to visiting famous temples and shrines during your trip to Japan, you should also consider visiting some of its beautiful national parks. For example, Nikko National Park in Tochigi Prefecture is home to many stunning temples and shrines that turn brilliant shades of red during autumn.

If you're looking for something more off-the-beaten-path, try visiting some of Japan's lesser-known islands. For example, Shikoku Island has several great spots for viewing koyo including Mount Ishizuchi and Mount Tsurugi.

Japan offers so much more than just beautiful landscapes though! Its vibrant cities are filled with delicious food options ranging from sushi rolls to ramen bowls. Don't forget about trying some traditional Japanese tea ceremonies either!

As you wander through Japan's picturesque countryside during autumn season，you'll be treated with breathtaking views of crimson maple leaves against blue sky or golden rice fields under sunny weather conditions.

So why choose fall? Well first there's the scenery – it’s hard not to get swept up by nature’s spectacular display when trees transform into colorful works-of-art.

Secondly，fall brings cooler temperatures making outdoor activities such as hiking easier.

Lastly，there’s something special about experiencing different seasons at once while still having plenty of daylight hours left.

And let us not forget about cherry blossom festivals which take place annually around late March/early April but if one life only gets one chance at traveling abroad then choosing spring might make sense too especially considering how unique these experiences can be

But remember: no matter what season you visit Japan it will always be worth it due largely because this country offers countless opportunities beyond just sightseeing such as immersing oneself within local culture participating in various sports events attending cultural festivals etc...
