World's Strangest Airport Attractions

Inhale Cinnamon-Scented Oxygen

Where: Tokyo’s Narita International Airport, Terminal 1, Oxygen Lounge Juko

Details: In this minimalist space, guests hook themselves up to self-serve tanks that pump exotically flavored oxygen, from eucalyptus menthol to cinnamon, into their lungs; choose from 10-minute (600 yen/$6) and 20-minute (1,200 yen/$12.50) sessions. The benefit? You decide—many claim increased oxygen eases headaches, induces alertness, and even reduces the effects of jet lag.
