More than 3,000 people, aged from 3 to 89, wrote down characters at the Nippon Budokan, following Japan's new year tradition of Kakizome (literally 'first writings').
Competitors, some of whom were assigned characters depending on their age and level, were required to finish writing on two pieces of paper within the allotted 24 minutes, Presstv reported.
One of the participants, Mai Abiru, said she hoped that writing her piece sincerely will help her have a good start to the year.
Calligraphy is a widely practiced and revered art in many parts of Asia. The act of writing Chinese characters is believed to sharpen the mind and improve concentration.
Winners of the annual competition that held during New Year in Japan will be announced at a separate ceremony on February 24.
