PLAN AHEAD!!! Seriously!
Major temples, gardens, and observation decks can get extremely busy.
Arrive early in the morning or late afternoon to avoid lines. Check official websites for ticket booking and operating hours. Many Kyoto temples and Tokyo attractions now allow online reservations, which is highly recommended. Some key things we recommend booking early:
Shibuya Sky (look up when they release tickets, don't go through 3rd party)
Break Beat Ramen + Pizza on 38th- again look up when they release reservations
Benitsuru Pancakes- a must do! Look on their website for most recent and up to date reservation system. David arrived around 7:30am and he got the 1:30pm reservation!
Most temples you can just walk up to them to be honest, but things like Sumo, Go-Kart, and other activities book out EARLY! Get gokarting in the night time!
