Nintendo on Wednesday said it swung to a profit in the first quarter due to strong demand for its Switch console.

The firm has said it expects Switch to help more than double its annual operating profit and end an eight-year sales decline that dogged its previous offering Wii U.

The company reported an operating profit of 16.21 billion yen ($144.95 million) for the three months through June, from a year-ago loss of 5.13 billion yen.

Nintendo reiterated its 65 billion yen operating profit forecast for the year ending March. It also kept its Switch sales forecast for the year at 10 million units.

The company sold 1.97 million Switch consoles in the three months through June, bringing the cumulative total to 4.7 million units. Demand has been so strong that Nintendo has found it difficult to keep up as queues get longer outside stores. The company has apologized for the shortage of Switch in Japan and pledged to raise production.

New mobile titles, such as Super Mario Run and Fire Emblem, drove first-quarter revenue from mobile gaming and related merchandise to 9 billion yen, from 1.6 billion yen a year ago.
