I want to know the timetable of iBus.

Please see the "iBus route map/timetable page" .
If you have any questions, please contact the Odakyu Bus Shin-Yurigaoka Office (telephone 044-299-9196), which operates the i-Bus, or the Inagi City Hall Administration Section.
Convenient timetable pamphlets are available on board the i-bus and at public facilities in the city (city hall, Hirao/Wakabadai branch offices, cultural centers, municipal hospitals, etc.).
