TOKYO -- NTT Docomo and KDDI, two of Japan's three major mobile operators, have been struggling to increase profits as they spend to keep customers from defecting to low-cost competitors.
Docomo's operating profit for the April-December period apparently edged down to around 830 billion yen ($7.65 billion). KDDI's profit likely rose slightly, to roughly 790 billion yen. The virtually flat showings mark a significant slowdown from a year earlier, when both carriers posted growth of about 20%.
