For those who know missing Japanese ESL student Natsumi Kogawa, it's been a baffling 10 days since she disappeared.

"She's not depressed, she wasn't going through any issues. Her relationships with her friends … was fantastic," said Jay Vergara, who along with others has been canvassing for information about where the 30-year-old is.

Kogawa , 29, was last seen in downtown Vancouver Sept. 7 and was last in contact with friends Sept. 8.

"On Thursday [Sept 8.] she had an appointment with one of her friends to meet up at 5:30 [p.m.]," said Vergara. "She messaged that friend at 11:30 in the morning on Thursday but that's the last communication anyone got from Natsumi."

Vancouver police say Kogawa is an experienced traveler who is studying English in Vancouver, while Vergara says she recently graduated and lived close to the Holdom SkyTrain station.

"She's a really hard worker and she would just study at the library by herself, we would hang out, she would study, I would do my work, or she might go to a park sometimes like the park at Science World and just study there in the sun," he said.

"Well because Vancouver is a hub to learn English," said Vergara. "And the concern is, 'hey one of our very own she came here to study, she disappeared so is that a cause of concern for people in Japan' or... in other places."
