At lunchtime, I noticed a sign for a seafood conveyor belt sushi restaurant, so I went up to the front of the shop. At the entrance, there was a bright red maple tree planted. In the backdrop, the sky was filled with early summer cumulus clouds, creating a rather peculiar scene. While there are indeed plants with red leaves during the transition from spring to early summer, there are not many trees as red as this one. I can’t say for certain, but it seems to be a maple tree called “De-shoujou.” Similarly, there are maples that have red leaves among their young foliage, gradually turning green, and then becoming red again in autumn. One well-known example is the “Nomura Maple.” There is also a maple called “Chishio (blood) Maple,” which is precisely like that. The phenomenon of tree leaves turning red is due to a pigment called anthocyanin, and it seems that various types of maples are born depending on the amount of this pigment. With that in mind, I entered the restaurant with a mixed feeling of early summer and autumn.
