Exhausted Japanese workers in need of a pick-me-up will soon be able to get a hit of canned oxygen at their local convenience store.

The oxygen will be sold for 600 yen ($5.50) in 3.2-liter spray cans of 95 percent pure oxygen, each of which comes with a small plastic mask attached to the top.

Users place the mask over their mouth and nose, then push a nozzle, which dispenses the oxygen for two to three seconds.
