A well-known Japanese columnist based in China has apologized to his Chinese readers for blatantly lying about his educational background.

"In my previous remarks, either publicly or privately, I mentioned that I was admitted as a student of the University of Tokyo but turned down that opportunity, which is not the truth," Yoshikazu Kato wrote on the Sina Weibo microblogging site, according to a report Friday in the state-run China Daily.

"I apologize for the confusion and misunderstanding caused by my immaturity, arrogance and ignorance," Kato said on the microblog Wednesday. "And I will try my best to endeavor to become a more trustworthy person."
