Square Enix wasn't the only Japanese publisher to announce strong quarterly results today. Metal Gear company Konami on Thursday reported earnings for the three-month period ended June 30, and revenue and profit--for the company overall and Konami's dedicated game division--were up year-over-year.

Overall, Konami posted ¥51.2 billion in revenue for the quarter, up 5.3 percent from last year's ¥48.6 billion. Profit jumped by an even more significant margin, rising 159.9 percent to ¥4.28 billion.

Konami's video game division, Digital Entertainment, posted revenue of ¥23.8 billion, which represented a year-over-year increase of 16.7 percent. Profit, meanwhile, did even better on a percentage basis, rising 78.5 percent to ¥6.5 billion.

A significant contributor to Konami's video game business during the period was mobile game Jikkyou Pawafuru Puroyakyu, which passed 13 million downloads following its launch in December 2014. In addition, Konami called out the World Soccer Collection franchise, the CrowsxWorst series, and the Professional Baseball Dream Nine brand as top performers during the quarter, each enjoying "steady sales."

Mobile games Star Wars: Force Collection and the PES Collection also earned "stable income."

In terms of Konami's home console business, Pro Evolution Soccer 2015's myClub mode enjoyed "strong revenue" from microtransactions, while Professional Baseball Spirits 2015 sold well.

Looking ahead, Konami said two of its big upcoming titles--Metal Gear Solid V: The Phantom Pain and Pro Evolution Soccer 2016--have "generated great expectations."

Today's earnings report comes in the wake of a recent Nikkei report which exposed details on the company's troubling corporate culture. In addition, Metal Gear creator Hideo Kojima is expected to leave Konami after The Phantom Pain ships next month, according to GameSpot sources.

In other recent Metal Gear news, Konami released a stunning new Phantom Pain trailer this week at Gamescom.
