Shibuya’s see-through toilets have a winter mode

At Haru-no-Ogawa Community Park in Shibuya, you can see the sink from the path on a warm evening. In November, even an empty stall looks frosted. In warm months, locking the door clouds the glass. That took too long in the cold, so the glass here and at nearby Yoyogi Fukamachi Mini Park stays frosted from about mid-October to mid-May. You can still use the toilets. The summer version lets you check that the stall is clean before you step in. The winter version saves you from wondering whether the wall has gone opaque once you’re inside.
