One sees stone-water basins (temizuya) like these at the entrance to every shrine in Japan. This is one I spotted at Chuson-ji temple in Hiraizumi. It is the first stage of the process in visitng a shrine, a ritual purification, using the long handled ladles to cleanse the hands and the mouth. This one is quite plain, many have their own pavilions.
As an exercise I drew it again with my Pigma Micron pens, which I started using only recently.
