Sakura
The arrival of the cherry blossom, or sakura, is a big deal in Japan. We arrived in Tokyo at the start of April, which was pretty much the height of the blossom. Unfortunately, since we arrived most days have been cold and rainy, with only occasional nice weather to go out and see them. At the time I'm writing this, only a few blossoms are clinging on. That said, we did see quite a few.
The picture above and below is the Joshinji temple, near our flat. Like many temples, its grounds have many cherry trees, making it quite spectacular at the time of year.
