information themselves. Another advantage is satisfying various laws and regulations, including Japan's Personal Information Protection Act and the EU's Data Protection Regulations, because the individuals have control over who they share their information with in these schemes.

### 2. Education sector

## (1) Study Suppli

### a. Overview of the Study Suppli service

Recruit Marketing Partners Co., Ltd. offers Study Suppli, a service for taking online courses for 980 yen per month, mainly to high school students. The company began in October 2011 with the release of Juken Suppli, an online study service for high school students. In February 2016, the company unified all its study services under the Study Suppli brand name to indicate it offers comprehensive learning support for elementary, junior-high, and high school students. There were around 250,000 Study Suppli members to date, as of March 2016.

### b. Characteristics of using smartphones

The first characteristic of Study Suppli, particularly because it is a service that targets smartphone use, is that users can take classes given by top-notch instructors anytime, anywhere, and as many times as they like, for the price of 980 yen per month. For example, the Study Suppli high-school and university entrance exam program (previous called Juken Suppli) offers more than 3,000 lessons in 5 courses and 13 subjects, broken down into 3 levels of difficulty.

High schools also use Study Suppli, and there are examples of high schools using Study Suppli to provide individualized support for students in classes with students at various learning levels. On a macro level, Study Suppli is thought to help close divides in education environments arising from differences in income and regions.

The second characteristic is making use of functions only possible with a video lesson format to continually incorporate user feedback and improve the service. For example, each video is mapped on a grid with the playback time on the horizontal axis and the percentage of viewers that continued to watch on the vertical axis. This allows administrators to analyze the factors in lessons that many people stopped watching partway through. Another function lets users give comments on each lesson chapter. This function is used to retake the lesson, if deemed necessary, and improve the lesson through feedback to the instructor.

### c. Data applications create values

For the Study Suppli high-school and university entrance exam program, each chapter in the 3,000 hours of lesson videos has been mapped to each question on practice problems and achievement tests. With this mapping, when a student makes a mistake on a certain question on an achievement test, the service automatically displays practice problems and the video lesson corresponding to the question's unit, making it easier for the student to overcome his or her stumbling block. And to see whether the student can still do the question where the mistake was made several days later, the instructor can check on a digital dashboard where the student is having problems overall. Recruit also offers Study Suppli for Teachers, a learning management system, without any additional charges to the instructor when Study Suppli is used in a high-school as a whole. With this learning management system, the instructor can monitor how each student is progressing with his or her particular difficulties.

### d. Expanding Study Suppli overseas

Recruit Marketing Partners made Quipper into a subsidiary in 2015 and started expanding its business overseas. Quipper was established in 2010 and began providing Quipper School in 2014. Quipper School is a tool for elementary, junior-high, and high school teachers to put all processes related to homework and in-class problems online. As of December 2015, Quipper School was used by 200,000 teachers and 3 million students in 9 countries. Quipper School content is localized for each country.
