Map of the Yamaman Yukarigaoka Line 山万ユーカリが丘線 in Sakura, Chiba Prefecture (map):
The Yukarigaoka Line ユーカリが丘線 is a 4.1 kilometer private railway line that serves the Yukarigaoka ユーカリが丘 new town development in Sakura, Chiba Prefecture. The system, which connects to the Keisei Main Line 京成本線 at Yukarigaoka Station ユーカリが丘駅, does not accept PASMO or SUICA (as of my visit in 2013). The train line forms a stemmed loop, like a lollipop. The area inside the loop is largely composed of farm land.
Yukari ユーカリ means ‘eucalyptus’ in English (with gaoka が丘, it means “eucalyptus hill”). The train line and community at large use a family of koala as their mascot (photos).
