By plane
If coming from Narita Airport, take the JR Narita Express to Tokyo station, and change for the Chuo Line for service to Hachioji about 2 1/4 hours, ¥3670. It is a real climb all the way up to the Chuo platforms, but since Chuo line trains start at Tokyo station, odds are you will probably find a seat. The alternative is to continue on the Narita Express to Shinjuku and from there board the Chuo Line, or the less-expensive Keio Line.
If you have a Japan Rail Pass, and if the timing is right, you may be able to reserve a seat on a Kaiji or Azusa train from Shinjuku and have a more comfortable journey to Hachioji.
The Narita Express runs directly from Narita Airport to Hachioji twice in the evening leaving Narita 19:45 and 20:44, and there are two trains from Hachioji to Narita in the morning 5:19, 5:55.
Six daily airport limousine buses run from Narita to both the JR and Keio Hachioji train stations in about 2 hours, 40 minutes ¥3700.
From Haneda Airport, the easiest way to Hachioji by train is to take the Keikyu Line to Shinagawa, from where you can take the JR Yamanote Line in either direction, to either Tokyo or Shinjuku station, to pick up the Chuo Line for Hachioji. It costs ¥1180 no matter which way you go; allow about 1 3/4 hours. Slightly faster, but requiring an extra transfer, is to travel via Yokohama.
