Access to Wako Campus

How to enter buildings in Wako Campus

To enter most of buildings in Wako Campus except for buildings in which cafeterias are, we need an ID card. For visitors, a temporal entrance card is issued at West Gate Guard Station. Please visit the guard station at "West Gate" first and fill out a form on your visit, e.g., the purpose, destination, host and so on. Once you get a temporal entrance card, you can enter any buildings by holding the card over readers at the front of automatic doors. When you leave the campus, please return the card to the guard station (West Gate).

* There are several cafeterias (C61, C72) in Wako Campus, but payments by cash are not accepted at cafeterias. Instead, you can pay by a prepaid IC card for public transport, e.g., Suica, PASMO. You can recharge it at the entrances of cafeterias. On the 2nd floor of the building C61, there is a small convenience store (you can pay by cash).


We have on-campus housing units (called I-House) for visitors in Wako Campus. If you are interested in staying at I-House, please let us know. For the detailed information, e.g., housing rates, please visit the link below.
