ARPU fell 5.2% from the prior year to 5,070 yen. Voice revenue fell by 198.3 billion yen, but DoCoMo said its efforts to increase data usage led to packet revenue growing by 1.06 billion yen.
DoCoMo added 1.93 million mobile subscribers during the year, and launched its LTE service, Xi, which by the end of March had around 25,000 subscribers.
Yamada said this was only half the company's target of 50,000 adds for the period, but added that the company will go after 1 million subscribers in the current financial year.
The company is forecasting a 2.3% increase in net profit and a 0.1% rise in operating revenues for this year. IE research analyst Yui Funayama told Telecomasia the earthquake is not expected to have a significant financial impact on Japanese mobile operators' earnings in the long term.
