The annual rainy season has arrived in Okinawa, Japan, six days earlier than average, heralding the onset of summer. While it is a regular event in the year, this early arrival of the rainy season could alter plans and routines of residents and tourists alike. It has also raised concerns among environmental experts who are closely observing changes in climate patterns.

In Japan, the arrival of the rainy season (Tsuyu) is of significant interest to the population as it directly affects daily life, agriculture, and tourism. From cherry blossoms wilting to ferns surfacing, the rainy season brings about significant changes in the scenery. Similarly, farmers rely on this season for their crops such as rice.

Different regions within the US and EU experience varied weather conditions and there is no specific period universally identified as a 'rainy season'. Yet, early or late onset of seasons due to climate changes is a shared global concern. Hence, it is closely monitored by environmental experts in these regions too.
