At the venue
On Kwansei Gakuin campus, an international roaming service called eduroam is available. In order to use eduroam, you must apply for an account at your own institution. Kwansei Gakuin University cannot create a guest account for the participants. Only those who have an account already can use the service. The information about eduroam is found here. Ask your institution to create an eduroam account for you.
However, given the large number of registered participants (550 as of July 31), you may experience a problem in using eduroam if many tries to connect. If you have other options, such as using a pocket wifi (see below), we appreciate you using them.
Outside the venue
Many hotels provide free wifi service for their guests. There are also free wifi hotspots. The information about those spots are available below.
