We trust you, your families and colleagues are well at this peculiar time. As we all know, the Omicron variant of Covid-19 has surged across the globe over the last few weeks at unprecedented speed. The new infections have broken records across many regions, including the United States and Europe.

As a result of increase in number of cases many governments, companies, and institutions have implemented much more strict travel policies which will directly impact the travel of our speakers and participants. The GSGAC2022 organizing committee and The Scientistt have been closely monitoring the situation and carefully evaluating the options we have. Given the diminishing value of having a physical conference due to travel restrictions, especially from overseas, and concerns over the safety of all our participants, we have decided to move the “hybrid” format to a fully virtual conference. This was a very difficult decision and surely will disappoint many of you who have long anticipated meeting your friends and colleagues in person after two years now.

In addition we have received requests from several participants to make the conference virtual as they are not able to travel from their country due to travel restrictions. Considering present situation, we believe moving to a fully virtual format is the right decision since the safety of our attendees comes first.

Thank you all for your understanding.

    Why Tokyo, Japan?

    Radisson - Narita
    650-35 Nanae, Tomisato 286-0221, Japan

    Prior to 1868, Tokyo was known as Edo. A small castle town in the 16th century, Edo became Japan's political center in 1603 when Tokugawa Ieyasu established his feudal government there. A few decades later, Edo had grown into one of the world's most populous cities. With the Meiji Restoration of 1868, the emperor and capital moved from Kyoto to Edo, which was renamed Tokyo ("Eastern Capital"). Large parts of Tokyo were destroyed in the Great Kanto Earthquake of 1923 and in the air raids of 1945.

    Today, Tokyo offers a seemingly unlimited choice of shopping, entertainment, culture and dining to its visitors. The city'...
