I saw this dual manhole cover for the first time.
Near this manhole, there was a single manhole which had the same design as above.
Most places in Japan enjoy Momiji-gari when leaves tinge with red or yellow. Momiji-gari is written "紅葉狩り" in japanese and its literal meaning is maple leaves hunting, but people don't gather maple leaves but just enjoy seeing beautiful shades of color, such as maples leaves and other autumn colored leaves.
Today I hiked Mt. Hakodate in a group and a fellow walker picked up a fallen leave of Katsura (Japanese Judas) tree. It smelled sweet and I liked it.
The leaves of the mountain have not changed their colors yet. But Urusi Japanese lacker tree leaves have change red. They are poisonous and if you touch it, you may be poisoned by lacquer.
Though it's getting colder and colder, but it's great to go hiking on fine days;)
