When Evernote Corp. CEO Phil Libin visited Tokyo's Shinagawa Joshi Gakuin in May, the combined junior and senior high school for girls came under the media spotlight — not only because it was unusual for a successful Silicon Valley entrepreneur to visit a girls' school, but also because of the progressive nature of the school.

Starting from the current school year, all of the roughly 200 second-year students in high school are provided with an iPad mini tablet computer loaded with Evernote software, which the school introduced in October 2013.

Students use the Evernote "cloud" to share text, graphics and videos from classes. A question posed by a student is answered by classmates or the teacher. Students even discuss social issues with their counterparts at cooperating schools in Australia and Singapore.
