All participants of ACNS2017 should be very careful about visa requirements and should make travel plan in advance enough. Visitors are fully responsible for acquiring all documents needed for entering Japan.
Japan provides waiver of visa requirements with more than 60 countries and regions. Please refer to the recent status on the visa waiver program from the Ministry of Foreign Affairs of Japan (MOFA).
If you need a visa for attendance, you should prepare all required documents according to the visa information page by MOFA. If you have any questions, please contact diplomatic establishments of Japan in your residential area.
We will issue an invitation letter ONLY for those who have presentation(s) at ACNS2017 upon request. If you need an invitation letter for visa application, please send the following documents to (acns2017-visa (at) crypto-cybersec.comm.eng.osaka-u.ac.jp) after paying the registration fee via ACNS2017 website and fixing your accommodation during the conference.
