It was pouring with rain for most of today, and so the obligatory patterned umbrella came with me - I call them ladies umbrellas as they all use the long style umbrella here, with the curvy handle. Because it rains a lot, they make the umbrellas "fun" to use and many of them are beautifully designed. The one I took with me today was black with bright green dots.
Anyway, when we got to the gallery, we were ushered to a little side room next to the main building, wondered where we were going and soon realised it was the umbrella "hut". It actually looked like Doctor Who's tardis inside and had hundreds of slots to leave your umbrella while you went and saw the exhibition. This is actually very typical of Japan and most shops will have a small version of this, or at least offer plastic tubes to slot your brolly in to keep dry.
