七十二候「虹始見」：春の訪れを告げる虹

日本語

七十二候の「虹始見（にじはじめてあらわる）」は、4月15日頃から4月19日頃までの短い期間を表す言葉です。

清明の末候にあたるこの頃になると、冬の間はほとんど見ることがなかった虹が、再び見られるようになります。

春の陽光が強くなり、空気中の水分量も多くなるため、虹が発生しやすい条件が整うのです。

また、田んぼや水面など、反射光の強い場所が増えることも、虹を見られる可能性を高めます。

虹始見は、春の訪れを告げる美しい自然現象と言えるでしょう。

English

The seventh of the 72 phenological periods, Niji Hajimete Arawaru (虹始見), refers to the brief period from around April 15th to 19th.

During this time, rainbows, which were rarely seen during the winter, can be seen again.

This is because the spring sunshine becomes stronger and the amount of moisture in the air increases, creating conditions that are favorable for rainbows to form.

In addition, the increase in the number of rice fields and water surfaces, which have strong reflective light, also increases the chances of seeing rainbows.

Niji Hajimete Arawaru is a beautiful natural phenomenon that heralds the arrival of spring.
