During the last 12 months, Twitter has taken off tremendously in Japan. By June, Internet research company Video Research Interactive counted
6.25 million registered Twitter users in Japan,
16.3 percent of the total number of people spending time online in the country.
This compares with 9.8 percent in the United States according to media researcher Nielsen Online. Twitter itself has said that every day 8 million tweets are sent from Japan, which amounts to about 12 percent of tweets worldwide.
During the World Cup, Japan set the world record for most tweets per second — 3,283 during the Japan-Denmark game.
