According to the announcement from the government of Japan, its border will open to tourists too in June 2022 at the soonest. It is a good news for both Japan’s economy and those who long to come to Japan, though the number of tourists who are allowed to enter the country in a day seems to be limited.
This article gives you a convenient way to get to the nearest station to your hotel from Haneda/Narita Airport. As widely known, Japan has terrible RUSH HOURS. You may want to avoid trains that are packed with Japanese office workers after your long flight, right?
Airport Limousine Bus is one of transportations that bring you to not only the centre of Tokyo but also suburbs including Kanagawa, Chiba, Saitama, etc. Personally, I recommend this, because you do not need to exchange train lines in the Tokyo’s complicated train system.

You can buy a ticket at the Narita/Haneda Airport by a machine as well as online in advance. The website provides some discount tickets. Check them out!
How to buy a bus ticket is straight forward. There are machines under the sign of Limousine Bus on the arrival floor of each airport. You can select a train station and buy a bus ticket. After purchasing a ticket, go outside and find the bus stop where your bus will come (there is a map around the ticket machine that shows you the number of your bus.)
At least go to the bus stop 5 mins before the leaving time. There is staff, and you are required to show the staff your bus ticket. The bus driver takes care of your luggage.
That is everything.
Hope you will enjoy your trip to Japan!
