Japan is often recognized for its long culture of deep connection to nature. This can be seen through its influence on how things are labeled in the past, or how it’s presented in haiku and ukiyoe. In modern times, this attention to nature is still preserved. One way this is demonstrated is through phenology to monitor the behavior of climate and seasonal changes, and the effects this has on living things. In Japanese this is called “Seibutsu Kisetsu” (生物季節).

A modern phelonomy dial (現代生物季節ダイヤル). The sections with numbers indicate the months within a year and their seasonal phases. The living things that wrap around in the dial are lined up accordingly to the months they are active. A rather older version of the phelonomy dial, this has many more entries (i.e. types of fish, fruits, vegetables). From the publication “Kishō Nenkan” (issue number unknown).
The practice of monitoring the seasonal effects on the weather, and how living things’ behavior corresponds to this is not only unique to Japan. Interestingly, keeping accurate data in accordance to phenology is treated with a standard of importance; while Seibutsu Kisetsu is an old tradition, the actual recording of this is fairly new. Started in 1953, observation groups (called Seibutsu Kisetsu Kansoku [生物季節観測] in Japanese) were established in different parts of Japan, which contribute on a regular basis each year. Through the use of meteorology (気象庁 kishōchō), key data on timing and behavior of living things in accordance to the weather conditions and how habitats are affected are recorded. This became even more of a necessity due to global warming.
The types of living things monitored was pretty extensive earlier on, but over the years the lists have become streamlined. Currently, vegetation and animals are categorized in Seibutsu Kisetsu, with vegetation including herbs, plants, flowers and trees, while animals consists primarily of birds, insects, and cold-blooded animals. Two categories on the types of living things prevalent in Japan were made: one is the regulated types, and the other is the selective types. The regulated types are those that can be found in any part of Japan, while the selective types are those that can be found only in specific areas.

Based off of recordings by observation groups, data is constantly compiled annually, consisting of detailed info regarding each of the living creatures’ patterns in Japan since the conception of this system. For example, the specific time when certain flowers began to bloom within each prefecture, or when certain birds migrate from one location to another, are recorded exactly. Each observation group make this information public in their own ways, usually through their own websites. This data is also compiled into a database and maintained by the Japanese Meteorological Agency, which is viewable online.
