Gained city status on the 1st September 1917. Population in 2004 was about 530,000.
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 Kaiji or Azusa train from Shinjuku and have a more comfortable journey to Hachioji.
One daily Narita Express does run from the airport straight to Hachioji in the evening, and there is one Narita Express from Hachioji to the airport in the early morning.
Six daily airport limousine buses run from Narita to both the JR and Keio Hachioji train stations in about 2 hours, 40 minutes (¥3700). As of September 2008, departures from Narita are at 7:50, 9:10, 15:10, 16:40, 18:10 and 20:40.
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.
Six daily limousine buses go from Haneda to the JR and Keio Hachioji train stations in about 1 1/2 to 2 hours (¥1700). As of September 2008, departures from Haneda are at 12:30, 15:40, 17:25, 19:25, 21:00 and 22:25.
From Tokyo Station, hop on a JR Chuo Line train departing from platforms 1 and 2 for the ride to Hachioji (50-60 minutes, ¥780).
From Shinjuku, you can reach Hachioji in as little as 38 minutes, either via the Chuo Line, or via tokkyū trains on the Keio line (¥460 on JR; ¥350 on Keio).

Other Modes Of Tranportation
in autumn,those colours change and it is very beautiful.
Mt. Takao is a 600-meter peak that is easily accessible by a combination of cable car and hiking, giving a little taste of nature in Tokyo. It is popular in the fall to see the changing color of the leaves, however springtime is also a nice time because you can see many beautiful cherry blossoms.
Start at the Takaosan-guchi (高尾山口) station of the Keio Line (this is the last stop). Just outside of the station a large map indicates hiking trails in the area. The first part of the main trail is steep, this can be avoided with a cable car or chairlift ride (6 min./¥470, ¥900 round trip). Once you get off the cable car, there are shops selling food and souvenirs. There is also Monkey Park, where for ¥400 yen (children ¥200) you can watch a demonstration (in Japanese) and learn about Japanese Macaques in this zoo-like exhibit. There is also a beer garden which offers an all-you-can-eat-and-drink course for around ¥3000, a welcome reward on the return trip for a couple hours of hiking. From there, it is about a 50-minute walk to the top of Takaosan (高尾山頂). However, there are many lesser traveled routes also available that may take longer but are more scenic. On the main route (Path 1) there are shrines and more food vendors. The entire path is paved, although there are steep stairs in places.
At the top of the mountain there is a visitor center, restaurant, and viewing platform where Mount Fuji is visible.
Leaving from Shinjuku, board a Keio Line express or semi-express train bound for Takaosan-guchi station (47 minutes/¥470), which is the end of the line. Note that not all Shinjuku departures go to Takaosan-guchi. Some semi-express trains bound for Kitano actually switch to local trains for Takaosan-guchi, which are convenient.
