The drop over this constructed weir across the Katsura (Oi) River in Kyoto can be viewed from the historic Togetsu-kyo Bridge near Arashiyama Bamboo Forest. Technically
a weir wall rather than a natural waterfall, but still impressive for its width, noise, volume, and picturesque river surroundings.

I came across this weir as part of a visit to the Arashiyama Bamboo Forest in Arashiyama, on the eastern outskirts of Kyoto. From the Bamboo Forest, which is one of the
most popular attractions in Kyoto, I headed through the Kameyama Park by foot, wandering through the cherry tree garden and then following the paved path down to the river.
At the river the weir forms a pool which backs up into the Rankyo Gorge, with chartered boats and row boats for hire from the little wharf beside the river, for paddling around
in the weir pool. There is a wooden fence in the water a few metres upstream of the weir, presumably to stop any tourists from being sucked over the falls in their row boats.

The falls can be viewed clearly from the concrete boardwalk that runs alongside the river, or by venturing across onto the Togetsu-kyo Bridge, about 100 metres downstream. According
to an information board on site, this historic wooden bridge was first built in the year 836. Walking across the bridge is extremely popular with Japanese tourists, with people shoulder to
shoulder on the footpath when heading across on my visit, even on a rainy day.
During cherry blossom season, the river banks upstream and downstream were scattered with cherry trees in bloom
throughout the surrounding park and forest, creating a picturesque view from the bridge, even in gloomy conditions.

The weir has a channel which runs along the northern bank of the river. The information board on site indicates that water along this channel has been used to generate hydropower since 2005 to
run the lights along the river boardwalk. If you head to the downstream side of Togetsu-kyo Bridge you can see where the channel drops back into the river.
From the bridge it is an easy walk back past several cafes and shops, many of which are built in a traditional style, to the Arashiyama light rail station that heads back into Kyoto.
