A recent poll of 440 salarymen in Tokyo and Osaka found that Tokyoites talk into their keitai for an average of four minutes a day while at work, while Osakans talk for 14.2 minutes. During their private time, usage increases, but Osakans still blab more than their Tokyo cousins, by 15.3 minutes to 11.5 minutes. The denizens of Kansai also beat out Tokyo in the number of keitai emails sent and received each day, both at work (3.5 received, 3.0 sent) and off the job (5.0 received, 4.7 sent). For Tokyo, the respective figures were 1.4 and 0.9 at work and 2.6/2.5 off the job. Interestingly, however, keitai owners in Tokyo had an average of 91.4 numbers stored in their units, as opposed to 75.7 for people in Osaka. When it's all said and done, there was hardly any difference in average monthly user charges. Tokyoites said they paid [yen]6,380; for Osakans, the monthly bill came to [yen]6,330.
