He may have struggled with blindness and financial hardships, but Michio Miyagi's legacy -- at Michio Miyagi Memorial Hall -- is the unmistakable sounds he produced on the koto, or Japanese harp.

His magnum opus, "Haru no Umi" ("The Spring Sea"), has become a famous traditional Japanese work -- so well known that there can be few people in this country who have not heard it, although it may only have been background music in a restaurant.

The memorial hall, in Tokyo's Shinjuku Ward, was built on the spot where Miyagi spent his last years.
