Softbank Corp. President Masayoshi Son proposed Thursday that his company offer a way to let cell phone users send e-mail messages from Tokyo Metro subway trains at any time.
Tokyo Vice Gov. Naoki Inose said the metropolis will positively consider Son's pitch.
People spend around an hour each day replying to e-mail after arriving at work because they can't do it on subway trains, Son said at a meeting he arranged with Inose by Twitter. Mobile phones are usually offline when subway trains are moving underground.
If people could reply to e-mail while riding moving subway trains, their productivity would increase substantially, Son said.
