In the traditional Japanese koyomi almanac, Nov 7th is set as the Ritto or official start of winter. But here in the warm southern Kanto the actual season lags about a month or so beyond this date, and fall colors and fruits can be enjoyed until early December. Among the many trees that change their leaf colors the katsura (Cercidiphyllum japonicum) is among the most kawaii. These trees are most at home along valleys in the high mountains, but in the southern Kanto are occasionally planted as street and park trees.
