OSAKA (Kyodo) The education ministry is trying to find a suspected entrance exam cheat who is apparently making use of a question-and-answer site on the Internet while the tests are in progress.

The alleged cheater, who used the online name "aicezuki," is believed to have posted questions from various tests on Yahoo! Japan's "chiebukuro" (pearls of wisdom) site by mobile phone while taking the entrance exams for Doshisha, Rikkyo and Waseda universities.

The education ministry on Sunday asked the universities involved to look into the matter and report back.

In the meantime, Kyoto University decided to file a police report because it was concerned the cheating is a violation of the Penal Code and undermines the fairness of the exams, officials said.

Kyoto University said Saturday that it began investigating the case after an anonymous individual who claimed to be involved with the national university alerted it about the posts.

Six questions were posted during the mathematics portion of the school's test Friday and two during the English test on Saturday, with third parties providing responses — mostly while the exams were in progress.

The tests were part of the second stage of entrance exams held by Kyoto University from Friday to Sunday.

On Feb. 8, the same person asked a question about English that was apparently used on the entrance exam held that day at Doshisha University.

Two other questions about English used on Rikkyo University's entrance exam appeared on the site on Feb. 11.
