A new soybean [Glycine max (L.) Merr.] cultivar 'Hatsusayaka' was developed at the NARO Western Region Agricultural Research Center in 2011. To develop a new cultivar with high lodging resistance and suitability for tofu processing, we selected plants from a cross between 'Kyushu 116' and 'Tachinagaha'. The date of maturity of 'Hatsusayaka' is earlier than that of 'Sachiyutaka' at Zentsuji, Kagawa (latitude 34°13' 37" N, 133°46' 39" E). The cultivar was classified into group IV based on the date of maturity. 'Hatsusayaka' has purple flowers, gray pubescence, rounded ovate leaflets and light brown pods at maturity. It has a medium-size stem and a determinate growth habit. It is resistant to SMV strains A and B. It has a tolerance to delayed leaf senescence. The seed coat of 'Hatsusayaka' is yellowish white, and the hilum is yellow, the seed size is medium. 'Hatsusayaka' is suitable for processing of tofu. 'Hatsusayaka' is highly compatible with the climate and soil of Kinki, Chugoku and Shikoku districts.
