I spent last weekend in Tokyo, with a side-trip down to Yokohama on Sunday to inspect and photograph a sailboat as a favor for a friend. I left Nagano Saturday mid-day as it was starting to snow. The weather in Tokyo, on the other hand, was excellent.
Saturday afternoon I wandered around Aoyama, where my grandparents lived in the 1930s. I found the neighborhood where they lived and tried to find their address (the house would have been long gone by now), but their actual address no longer exists.
Japanese addresses are notoriously hard to find. Cities are sub-divided into wards, then districts, then neighborhoods, then blocks, then non-sequential houses. There are no street addresses. Finding a specific place usually takes some wandering.
