You look down on these trees from a wall. Kaikoen, the park inside the ruins of Komoro castle, has Somei-yoshino and higan cherries and one variety that belongs to the town alone: Komoro-yae-benishidare, a weeping cherry with doubled petals and a notably deep colour, according to the local tourism bureau.

They do not open together, and the gap is deliberate enough to notice. Somei-yoshino comes from the middle of April, the Komoro variety from the end of it, which is far enough apart that some people make two trips.

The other thing about this site is the angle. The stonework around the main bailey is old and thickly mossed, and from the top of it the ground falls away sharply on the inner side.

What is below is the baba, the old riding ground, and in the second half of April it is packed with cherry trees. So instead of standing under blossom and looking up into it, you stand on a wall and look down onto the surface of it, as though at water. The stone is grey-green with moss and several centuries old, laid by people who were not thinking about flowers. The colour sitting on top of it looks temporary by comparison, which of course it is.
