Construction of the Dragonfly sanctuary began in 1986 with the conversion of some abandoned paddy fields into ponds with a variety of flowers selected to be attractive to dragonfly. Work has continued and now includes a sizable museum and fresh water aquarium. Of course, not all the dragonfly species are observable in the nature park at any one time, the different species have hatching periods between March and December.
If you arrive on very wet day, like we did, you may see only a couple of the insects outside in the park. However, while the specimens mounted in display cabinets inside can't quite match the sparkling iridescence of real live creatures, they certainly give you an excellent display of the wide variety that exists.
Access is 10 minutes by car from Nakamura station on the Tosa Kurishio line. Many more pictures on the Dragonfly Kingdom website. ( Japanese text only)
