Microseason: Praying Mantises Emerge

PRAYING MANTISES EMERGE

5 - 10 June

The emergence of the praying mantis marks an early summer transition. Tiny hatchlings, newly released from their protective eggs, hop onto the surrounding grasses. Kamakiri is one of the few insects widely recognized across Japan as a beneficial presence in the field.

Before the widespread use of chemical pesticides post World War II, farmers observed the life cycles of kamakiri with great care. Its carnivorous nature makes it a natural predator of pests that can harm crops like grasshoppers, aphids, and moth larvae. Kamakiri have served as unofficial protectors, helping to reduce damage without reliance on man-made modern intervention.

In recent years, with the resurgence of traditional natural farming methods, the significance of kamakiri has been revisited. Chemical pesticides, herbicides, and fertilizers disrupt ecological balance. By allowing the mantis and other predatory insects to flourish supports biodiversity and promotes a more stable pest control system over time. Everyone needs to be present in order for the natural world to make sense.

The appearance of young mantises this time of year coincides with the wheat harvest, and their growing size mirrors the growth of summer vegetables. In regions such as Nagano and Niigata, people read the kamakiri’s eggs as prophecies for future weather. When laid high on plant stalks or fences, these eggs were said to foreshadow deep snowfall during the upcoming Winter months.

In Edo-period metalwork, particularly sword guards and inro fittings, kamakiri appear in carved or inlaid relief, often set within Autumnal scenes. Its forearms folded like a monk in prayer, yet deadly in action, the insect is a symbol of strength and precision. This dual nature also appealed to practitioners of martial arts. The mantis boxing style that developed in China and made its way to parts of Japan, mimicked the kamakiri's fast, angular movements. Whilst relatively rare, kamakiri can also be seen in some textiles, lacquerware, and folk toys that also serve as amulets.  

Toroyama at Gion Festival, Kyoto

In Kyoto’s historic Gion Festival, Toroyama, or the Praying Mantis ​float is a longstanding favorite amongst spectators. It features a mechanized praying mantis mounted atop the float, along with spinning wheels on a miniature imperial ox cart. The origins of this float date back to 1376. It is said to commemorate Shijo Takasuké, who died in battle against the forces of Ashikaga Yoshiakira. Drawing upon a Chinese classical tale, the float was created by placing a praying mantis atop the Shijo Family’s imperial cart as part of the parade procession.
