Do you know 24 sekki (Solar Terms) and 72 kō (Micro-seasons)?

Understanding Japan’s Seasonal Rhythm: The 24 Solar Terms and 72 Micro-seasons

In Japan, there is a unique way of dividing the seasons called the “24 Solar Terms and 72 Micro-seasons.” This traditional Japanese calendar divides the year into 24 segments, known as Solar Terms, and further into 72 smaller periods, called Micro-seasons. Each of the 24 Solar Terms reflects the season and is divided into three Micro-seasons, each lasting about five days, resulting in a total of 72 divisions throughout the year.

Terms like “Risshun” (the beginning of spring), “Shunbun” (the vernal equinox), “Geshi” (the summer solstice), and “Risshu” (the beginning of autumn) are well-known among the Japanese people.

Risshu and the 72 Micro-seasons

Although we are still experiencing scorching heat every day, “Risshu” (the beginning of autumn) actually started on August 7th. According to the 72 Micro-seasons, Risshu is divided into the following three periods:

“Suzukaze Itaru” (涼風至): The cool breeze begins to blow.
“Kansen Naku” (寒蝉鳴): The cicadas start to sing.
“Fukaki Kiri Matou” (蒙霧升降): Thick fog begins to rise.

The Upcoming “Shosho” Period

Next, we have the “Shosho” period, which marks the time when the heat begins to subside, starting on Thursday, August 22nd. The 72 Micro-seasons divide Shosho into the following three periods:

“Menpu Hiraku” (綿柎開): The cotton bolls begin to open.
“Tenchi Hajimete Shukusu” (天地始粛): The heat finally begins to calm down.
“Kokumono Sunawachi Noboru” (禾乃登): The grains ripen.

Japan’s Unique Seasonal Sensitivity and Cultural Delicacy

This detailed division of the seasons is uniquely Japanese. In my August 4th blog post, I introduced “Shijuhattcha Hyakunezumi (48 Browns 100 Grays),” colors from the Edo period that reflect a similar sensitivity. Just as the seasons are finely divided, so too are the colors, which may be a reflection of the Japanese character. This cultural delicacy is one of the characteristics that gave birth to uniquely Japanese sensibilities like “Wabi-Sabi” and “Iki (Sophisticated).”

Travel Advice During the Scorching Heat

However, despite the approaching Shosho period, the extreme heat continues, likely due to global warming. For travelers in Japan, walking outside for sightseeing can be dangerous due to the risk of heatstroke.

Therefore, I recommend enjoying traditional cultural experiences indoors. Not only can you learn about and enjoy Japanese culture, but you can also contribute to the preservation of these traditions. Conducting these activities in air-conditioned spaces is a great way to avoid the effects of the intense heat.

Conclusion

During these hot months, consider engaging in traditional cultural experiences indoors. If you prefer to explore the town, I suggest doing so in the evening when it is cooler. I believe this is the best way to enjoy your summer travels in Japan without turning your trip into an ordeal. Please give it some thought and make the most of your visit.
