"Although the corporate market is relatively bigger than the telecom carrier sector, Huawei needs to factor in aspects like the varied demand from various verticals," said Xiang.

"Huawei did well in China as the company focused on one or two verticals at a time. It should use a similar approach in overseas markets like Japan also."

Japan is a small market for Huawei, whose global annual sales revenue amounted to 239 billion yuan ($38 billion) last year. Its 2013 sales were 38 billion yuan in the Asia-Pacific region, to which Japan belongs. The company's biggest markets are China, Europe and North America, according to its financial report.

Enterprise business is also a small segment for Huawei compared with carrier network business and consumer electronics.

Total sales of the company's carrier business was nearly 10 times bigger than the corporate business last year.

The 2013 sales to enterprise customers were a little more than 15 billion yuan, a jump of 32.4 percent year-on-year, it said.
