Aquatic Plant Garden

Part of the garden was designated as a “National Historic Site Jindai-ji Castle Ruin”.
In the pond and waterways, reed grasses, Amur silver-grasses, Wild rices, Typha orientalis and Acorus gramineus (Japanese rushes), as well as water irises, bur reeds, cow lilies, water fringes, primulas, Japanese loosestrife, and Lobelia sessilifolia are planted.
In the Iris Garden in June, you can enjoy seeing about 1,500 Japanese irises seedlings, with 50-species.
