Should you find yourself with a 24 hour layover in Tokyo, and Sayaka (the best Air Canada Stewardess in the world), is not working your flight, here are her 'to do' suggestions, which may save you from a rather loopy lockdown in the airport.

Where To Go 
Since Tokyo itself is quite far away from the airport, and quite expensive to get to, Sayaka suggested we go to Narita Keisei Station (three stops from the airport).

Where To Eat
When you exit the station, turn right, you will see a two story restaurant with a take out window called Osho, this is Sayaka's suggestion for cheap eats, we had gyoza and a noodle dish and some sort of green apple alcoholic beverage. It cost next to nothing, was tasty, and the staff was sweet. 

Where To Sleep
It's a bit awkward to find, but APA Hotel (906 Hanasakicho, Narita, Chiba Prefecture 286-0033, Japan) is cheap and clean. The rooms are hilariously tiny, like a classy IKEA clad camper van, but it does the trick and it convenient and modern. 

Sayaka, our stewardess, told us this areais where all the flight attendants and pilots go out when they themselves have a layover, and they are to be visited in this order:
The Barge Inn: British style pub, nothing too special but not bad. The owner was really kind and helpful!  
Cage Bar: Tiny hole in the wall Karaoke bar, you'll find it if you turn left onto the main street out of Narita Keisei Station. It is half a block up on the second floor and has a blue sign. The experience is funny regardless of your group number or talent level!
Jet Lag & Skin Pray: Jet lag is the lounge below the after hours club skin pray, you can apparently party all night, so if you are the type with extra energy, lock your luggage up at the airport before you head to Narita station and giver'! 

Daytime Activity
The Naritasan Shinshō-ji Temple is walking distance from the hotel/station. It is a pretty and exciting walk through the market streets, don't be surprised if you are the only westerners in sight, and make sure you try the The temple is said to date back to 800 AD, there are a number of classical Japanese pagodas, a pretty park with fountains and statues and a garden with a beautiful waterfall within the grounds.
