Ms Yuri, 38 years old, is captain of protest boat, and an activist with Henoko Dream, which is part of the Anti-Helicopter Base Council. She used to work as caretaker for elderly people. When working as a caretaker in Okinawa, she found many elderly people had a lot of scars in their bodies. Many elderly people told her that they were injured when they were children in the Battle of Okinawa.

When she visited Henoko from Naha, she was asked to take a license to become a captain of protest boats. After taking the license, she began to want to be involved more in the Henoko protests, eventually turning it into a full time occupation.

She has been an activist for one year. Her main roles are captain of their protest boats, monitoring the movement of Japan Coast Guard and the Okinawa Defense Bureau in Oura bay.

She was featured in a documentary film that has been screened under the title "Ikusaba Nu Tudumi’ meaning ‘Stop Okinawa becoming a battlefield again’ more than 200 times across Japan.
