Poppo no Oka

Poppo no Oka is a hillside site in Isumi, Chiba, where about thirty retired railway vehicles are kept on display. Some belong to the site itself. Others belong to volunteer preservation societies, each of which looks after its own vehicle.

Several carriages have been given new uses. A Chiba Urban Monorail car houses the shop, which sells railway goods and fresh eggs from partner farms. The cafe, Cafe TKG, uses the Isumi Railway car Isumi 204 and is named for its tamago kake gohan, raw egg over rice. Cars from the Choshi Electric Railway and the Hokuriku Railway serve as rest areas.

The collection runs from main-line trains to small industrial engines. Former Japanese National Railways vehicles include two 183-series express cars, a 583-series dining car, a 781-series Lilac express car, a Kumoni 83 parcels car, blue sleeper carriages, guard's vans and shunting engines. From smaller lines come a Keikyu car, a Nagano Electric Railway car, locomotive No. 4 of the Kaya Railway, a trolleybus from the Tateyama Kurobe Alpine Route and the Tanzawa cable car from Mount Oyama in Kanagawa.

Most carriages can be entered. Some preservation societies have raised money for repairs through crowdfunding. For children there is play equipment and a hand-pumped trolley, and at weekends a shunting engine gives rides in a guard's van when staff are on site.
