When walking around in Tokyo try to keep to your left. Especially on the escalator so that people can walk past you.
On day 2 we went to TeamLab Borderless it was an amazing experience and my daughter loved it. I recommend getting there at opening hours to beat the crowd. It cost around 4,000 Yen/$27. We spent about 3 hours there and it's inside a mall so you can shop afterward.
I recommended purchasing your tickets on Klook their prices are very reasonable and sometimes cheaper than the website.
For mobile service, I purchased an E-Sim from Klook you can get 10g of data for around $11. 20g of data lasted us 3 weeks in Japan.
Lunch we ate at Savoy Azabujuban one of the best if not the best pizza I ever ate. It's worth the visit and they have several locations. Their lunch special combo is tea, appetizer salad, and a pizza for 1100 yen/$7.38
For dinner, we decided to find a random Izakaya and ended up at Gembei. The food was pretty good and was a fun experience for us.
