Running out of battery power on your smartphone in Tokyo? Don't panic, soon you will be able to access a number of free recharging stations at popular sightseeing spots across the metropolis.

The Tokyo Metropolitan Government announced this week that the first solar-powered battery charging stations will be rolled out as soon as October, starting with tourist mecca Tokyo Tower and the Toranomon Hills business complex.

A joint project with electronics firm Sharp Corp., which manufactures the charging stations, the two City Charge sites are compatible with all mobile devices.
