TOMBO

TOMBO is the Japanese word for Dragonfly.
Other names for TOMBO in Japanese will be AKIDU or KAGERO.

AKIDU is an ancient word for TOMBO, and it is also the old way of expressing JAPAN. The reason is said to be that an ancient emperor looked at Japan from the height and said that it is a round country just like two mating dragonflys.

蜻蛉 (sorry for those who aren't able to see Japanese characters)will be the KANJI for TOMBO. We also read this KAGERO.
KANJIs are unique, because you can read it in many ways, and one character can be a combination of two or more characters. In this case, you will notice that both KANJIs include a 虫 on the left side. This means "Insect". The right side of both KANJIs are different letters, but they both mean "Sound".

TOMBO patterns are frequently used in KIMONOs and OBI*s. The picture above is an OBI. You will notice that many patterns of KIMONOs are inspired by living things, plants and natural landscape. Dragonfly designs were popular among BUSHI (or SAMURAI), because dragonfly only flies forward and never fly backward. This is expressed ISAGIYOI （潔い）, meaning graceful.

*OBI is a waist tie for kimonos. OBIs could be very expensive too. Coordination of KIMONO and OBI is as important as the KIMONO itself. Btw, I have a feeling that Obi-wan of Starwars comes from OBI, since it is a famous story that the outfit design in the movie series were inspired by KIMONOs. AMIDARA, the name of the princess, is a Bhudist God too...May the force be with you!
