Tap in at the back, ride, tap out and pay at the front. Say the stop name if you are unsure. A day pass is only worth it if you ride three times. Walking is usually faster inside the east hills.
Temples are a morning sport
Anything famous is ruined between 10 and 3. 7am is civilized. Many gardens close at 16:30, not 18:00. Last entry is often 30 minutes before close.
Shoes you can lose in three seconds
Slip-ons. You will be in and out of temples all day. White socks if you care. Do not step on the tatami threshold.
