Undertook the planning and development of the ranking app "Rakuten Ichiba", the biggest shopping site in Japan. Rakuten Ranking is an iPad application which introduces a sales ranking from 6 million items sold at Rakuten Ichiba. More then 1000 genres are included in the ranking. The application provides the information in ways that are easy for the users to look at, understand and use.

In this project, we aimed to provide a smooth operation between "a list of information in an overview" similar to looking at leaflets and "narrowed-down information" from an interested genre to its subgenre. We made the paper prototype to create an user interface which utilizes iPad features.
Also, the application has a keep function in which users can keep product that they are interested in for 3 months. Kept products can be viewed according to their registered date and genres.
Users can post to Twitter from each product detail page. They can share their information casually by tweeting. Rakuten Ranking won No.1 in iPad free application ranking in iTunes AppStore in 2 days after its release.
