On the way to Nago on Hwy. 58 stretches a wide, green field on the west side of Onna Village. This area is called Manzamo, literally meaning a place where 10,000 people are able to sit together. It is situated on a field created by coral reefs, and its grassy top is a familiar place for picnics and sports games. It is a sheer 50 meter drop off Manzamo to the bottom of its cliffs where strong waves constantly splash the spray of the sea.

The northern views from the cliff top of Manzamo are spectacular, where one can see the deep blue waters of Nago Bay, Mount Katsu, Mount Yae on Motobu Peninsula and Ie Tacchu, the rocky outcrop on Ie Island.

One day in 1727, the villagers welcomed the Shuri King Sho Kei on his visit to Manzamo; and Nabi Onna, a well-known and passionate poetess of the time, created a poem for the king. From that time, Manzamo has been considered a site that inspires poetic feelings.

The Onna Village Board of Education has set aside a box to collect the poetic works of visitors to the site in memory of Nabi Onnafs poetizing. They plan to publish a book from a collection of the works once a year and send copies to the authors as a memento of visiting Onna Village.
