Gaming machine manufacturer Konami Corporation has reported a significant increase in operating income and revenues in its latest financial statement.

For the six months to September 30, 2008, the firm, which also has digital entertainment and health and fitness business operations, consolidated net revenues stood at ¥146,904m (US$1,502m), up from ¥133,743m ($1,367m) during the same period in 2007, while operating income rose from ¥13,042m ($133m) to ¥22,844m ($233m).

The company also said its net income reached ¥11,964m ($122m), compared with ¥6,288m ($64m) in the first half of last year.

Among the factors cited as reasons behind its success during the quarter ended June 30, 2008, were the "strong" sales of its K2V series slot machines and five-reel spinner Advantage 5 in North America and "solid" sales of its arcade machines, such as jubeat and Horseriders.
