A Chinese human rights activist who has been refused re-entry into his own country entered the 10th day of his sit-in at Narita Airport on Friday.

Feng Zhenghu, 55, has been living in the restricted area outside the immigration gate since Nov. 4, according to airport officials and his supporters. He has been subsiding on biscuits he was carrying and drinking tap water in a bathroom.

His visa to enter Japan is valid until June 2010.
