In ancient times, Japan was called "Akitsu shima" which means an odonates' island, and also called "Toyo ashihara mizuho no kuni", a wet island having a rich crop. Because we Japanese have lived on rice for more than 2500 years with a huge number of odonates which emerge from paddy fields, they are the most familiar insects for us. I will introduce Japanese odonates with many photographs and topics.
