Ueno Zoo Monorail is a 0.2 mile-long monorail operated by the Tokyo Metropolitan Bureau of Transportation, connecting west and east areas of the Zoo. This is the first monorail in Japan, which was opened in 1957. The line lies almost entirely within the Zoo, but the line was constructed in accordance with former Regional Railway Act 1919. Even today, the line is operated and maintained on the basis of Railway Business Act 1986, which means that this Monorail is registered as a genuine railway despite it looks a kind of amusement ride.
Ueno Zoo Monorail was built as a test line of "alternative means of transportation" which must be more efficient and punctual than trams. It is based on German Wuppertal Suspension Railway system with some modifications. However, it became clear that monorail is not always suitable for the city of Tokyo, as it is expensive to build while it is capable to have only limited number of passengers. The Bureau decided not to make any new monorail, and instead started expanding underground and bus networks.
In January 2019, the Bureau announced to suspend the operation of the Monorail from 1st November, as the current rolling stock got old. Its future is bleak as it costs 1.8 billion yen (approx. 17 million USD) to introduce a new fleet. The Bureau intends to have discussions with specialists, visitors and local residents, but the Monorail is likely to be closed permanently.
Currently, one unit of 40 series (built in 2001) runs every 7 minutes during opening hours of the Zoo. It costs 150 yen for an adult and 80 yen for a child, but note that admission fee is required to get into the Zoo. It takes about 90 seconds from east to west areas and vice versa. The last service is scheduled to be held on 31st October.
