A Chinese man asked the Consulate General of China in Sapporo, Japan on Tuesday night to help find his daughter, saying she went missing in the city, the consulate said.

The consulate said it has started emergency procedures to find Wei Qiujie, 27, asking Sapporo police to spare no effort in investigating and searching for the woman. It said it is working with authorities in China to help Wei's family make arrangements to quickly go to Japan.

Wei, a teacher at an elementary school in Shaowu, Fujian province, arrived in Sapporo by herself on July 18 for a sightseeing tour of Hokkaido and was expected to return to China this past Tuesday.
