Gakkyusha Co., which runs cram school networks in Japan and overseas, said Thursday it will donate knapsacks worth a total of ¥5 million to children at welfare facilities, becoming one of the first companies to join hundreds of anonymous individuals in the country in making donations for underprivileged children.

"As a company in the field of education, we were deeply touched by the 'Tiger Mask Phenomenon,' " the Tokyo-based company said in a statement, referring to a series of anonymous donations to children's facilities across the country under the names of cartoon heroes and other characters since Christmas Day.

Unlike citizens who have made donations anonymously, Gakkyusha said it has decided to make its move public, because it is a publicly traded company and it would be inappropriate for the company to make a secret expenditure. The company is listed on the Jasdaq market.
