Hanahasu Koen (Lotus Park) in Southern Echizen, Fukui, has an extensive collection of lotus (100 kinds from around the world) in its vast fields (they have lotus fields just across the street from the park). It truly is a photographer's heaven if you are interested in taking close-up photos of flowers. Since it's not a pond but a field, you can walk through the paths and take photos of them up-close to your heart's content!
