The variety belongs to the early maturity group: under the conditions of Nagano Prefecture (Japan), about 50% of the harvest is collected in late June. The plant forms a relatively compact bush.
The berries of the variety are characterized by uniformity, a relatively large size, and high firmness, due to which the fruits are less prone to cracking. The flavor of the berries is evaluated as sweet, with an optimal balance of sugar and acidity. On the international market, the variety is known under the trademark SUMMER CHANCE.
