The other day my friend Paul and I went for a two-day backpacking trip in Ashiu, in the Kitayama Mountains north of Kyoto. Ashiu is one of the few remaining areas of virgin forest left in Japan. It's a storehouse of incredible biodiversity. It's surprising to see so many broadleaf trees in Japan - one gets used to all the industrial cedars you see growing on most of the hills. We bushwhacked down a steep river and camped by the Yura-gawa before hiking out over a rather steep ridge. It was excellent, leech bites and all.
This shot gives you a good idea of how rich the green is in Ashiu.

This is me at the base of one of the rivers that flows into the Yura-gawa.

Here's Paul with a mossy river.

Here I am drinking some of the best water on earth.
