Japan may be almost solely responsible for Twitter’s growth at this point

As Twitter fumbles around for a buyer or a business plan, the company can be hard-pressed at times to point to any hopeful signs in its business.

But one bright spot stands out in the quarterly earnings statement that Twitter filed this week with the U.S. Securities and Exchange Commission: Japan.

According to the 10-Q, Japan represented $73.9 million of the $616 million in revenue that Twitter reported in the three months ending September 30. This was the second straight quarter that Japan accounted for more than 10 percent of Twitter’s revenue, making it the company’s most important market outside the U.S.

Just as important, that $73.9 million was up from $61.2 million in the second quarter ending June 30. Twitter’s revenues from the second quarter to the third quarter grew $14 million. That means Japan represents almost all of Twitter’s growth over the past three months.

Strangely, according to transcripts of the earnings calls for the third and second quarters, Twitter execs opted not to highlight this information or explain what’s going on in Japan. If it were me, I’d be tooting that horn pretty loudly. But the company also doesn’t break out its monthly users stats by country, so it’s hard to know if Twitters ads are just doing better in Japan or if the service is still attracting more users there.
