Maddie S's City Tips
Taxi meters are cheap and they make it easy to get to a location. Doors open and close automatically.
The Tokyo Metro goes almost anywhere in the city, and tickets are mostly purchased on a single-ride basis, at machines. If you are having trouble with the machines, seek a teller.
Some restaurants (especially traditional or themed) do not allow photos. Be aware of policies via signs posted, and be courteous, as you are expected to police yourself.
At restaurants, offering the wait staff a tip is considered taboo. In taxis, the practice is completely optional - use your discretion, but 20% is usually a fair amount.
Some underground lines are run by different companies, so you may have to purchase a separate ticket for transfers. Sticking to one line where possible will save travel time.
You can purchase a PASMO card (refundable deposit), a metro pass that you can top up at any time. It does not give travelers a discount, but it does work across lines.
Get your best foot fashion going! Wear matching socks that you're happy to show off - some establishments require you take off shoes. A must if you are visiting a home, too.
