Strong demand has Irvine-based Kura Sushi USA Inc. (Nasdaq: KRUS) President and Chief Executive Hajime Uba optimistic about the long term for the revolving sushi chain.

The restaurant operator, Uba said, had 23 of its 25 restaurants open by the end of the company’s fiscal fourth quarter ended Aug. 31, with online ordering, Grubhub delivery and outdoor dining helping drive sales during the period.

Kura’s fiscal fourth quarter revenue fell 71% from the year-ago period to $5.5 million, missing consensus estimates of $7.3 million.

Kura Sushi reported a loss of $6.8 million. That compares with analysts’ targeted loss of $4.8 million.
