I would suggest to take the train 🚆 from the airport to Tokyo. Download the app. It's fairly easy. Purchase the JR train pass. Get it validated once you get off your flight ✈️ and ur good to go. Train station is only about a 10 minute walk 🚶‍♀️ from the Apartment. Don't bring too many suitcases as there are lots of stairs on many rail stations and not many escalators. Hope this helps.

Yes, although Tokyo is very pedestrian and pedestrian friendly and parking is quite expensive. I would suggest to try the train 🚆 and walking around 1st b4 renting a car. We were there for 2 weeks and didn't need a car at all. Bullet train 🚅 was very efficient and so were the local trains. JR pass will allow you access to most of local transportation including Bullet train except for some commuter trains to which you have to pay a minimal fee. You need to make reservations on the bullet train. But there's no fee.
