Japan's Toshiba Corp saw better-than-expected television sales in November and December thanks to a spike in Japanese sales, the head of the company's TV unit told Reuters in an interview on Thursday.

But Masaaki Osumi said sales of 3D models designed for use with special glasses had fallen behind expectations, accounting for only about 15-20 percent of large TVs sold, compared with an initial target of 50 percent.

He added that the company would meet its 15 million unit TV sales target for the year to March if Japanese sales remained flat on the previous year for the next three months.
