How long does it take to get to Tokyo Japan from Misawa Japan?

This depends on the means of transportation that you choose.

Misawa has its own Japan Railways Station that connects to Shin-Hachinohe, which is a station on the Touhoku Shinkansen Line. Going from Misawa to Hachinohe depends on the train (Express or normal train), but will normally take around 15 minutes. From Hachinohe to Tokyo it takes about 4 hours on the Shinkansen and altogether costs around 16'000 Yen.

There also is an airport in Misawa that connects directly to Tokyo, with flights leaving several times a day. Going by plane will take around 90minutes to Tokyo Haneda Airport.

From Misawa you have a connection to the 東北自動車道　(Touhoku Expressway) to Tokyo, which is about 690km and will take 9 hours by car.
