Koi and Golden Week in Japan
Download Wallpaper:

In late April to early May Japan, celebrates several holidays that form the Golden Week. April 29th, the birthday of Emperor Hirohito, is celebrated as Showa Day, May 3rd is the Constitution Day, May 4th is the Greenery Day, and May 5th is the Children’s Day. The latter is celebrated by Japanese families by putting out koinobori — windsocks in the shape of the koi carps that symbolize each member of the family.

From April 28th (13:00 GMT) until May 5th (11:00 GMT), play 3 battles using Japanese vehicles (rank III or higher, with an activity of not less than 70%) to receive the “Koi” decal.

Complete the task in random battles, except for Enduring Confrontation missions and [Assault] mode. Track your progress in the hangar by clicking Nickname → Achievements → Holidays → Golden Week.
