The Telecommunication Carrier Association (TCA) and all five Japanese mobile carriers (docomo, au, Softbank, e-mobile, willcom) announced on April 16th, that the usage of filtering services on mobile phones reached an all time high of 5.7 million subscribers. That’s an increase of 780.000 in the last 3 month and an increase of 2.3 million in the last year. Young Japanese under the age of 18 are therefore unable to see content which is on the blacklist. However parents can decide and individually activate sites at their child’s phone if they think its appropriate.
