Due to the delay in containment of the COVID-19 infection , the Organizing Committee has decided to postponed the IWGO-4 (Oct. 17-21, 2021, Nagano, Japan) for one year after thoroughly considering all options.

This necessary decision is made to ensure the personal safety of all speakers and participants. The new date is scheduled for fall 2022, and we will inform you of the details in the future.

We appreciate your understanding in advance.

With best regards,

Yoshinao Kumagai, Executive Committee Chair, IWGO-4.
