Flowers which color the four seasons

You can know the real sense of each season by flowers. The best sight to see is "Ayama (iris)" on the waterside.

The beach in Kashima is on the northern limit of "Hamanasu" (rugosa rose) which opens red-violet flowers in summer.

In winter swans come back to Kita-ura lake. The well-preserved environments of nature enable us to see a rich variety of beauty for all seasons.
