This year's cherry blossoms will also start to disperse in a few days, so if you want to take pictures, it may be better to take them before it rains.
By the way, as you may have noticed, did you know that there was a lump of calcified limescale on the stairs of the open-air bath? It became hard as a stone and could not be removed by chemicals or cleaning.
* The photo below is before cleaning.
This time I removed the lumps of limescale.
It took a long time to remove something that was so hard and stone-like, but I took it steadily and it became completely clean.
I think you will be able to use it comfortably next time you use it.
