iiba is a child-rearing crowd-sourced review platform based on the evaluation economy and token economy. Users receive points for recording their movements and actions and for sharing reviews from the perspective of child-rearing. The company can obtain data on trends and thoughts of parent users, making it possible to build an effective platform for both parties. Based on the hypothesis, the accumulation of data will result in a map optimized for parent users in which only truly favorable places appear, as well as a behavioral design that encourages local consumption and contributes to economic development. Research and development will be conducted to demonstrate these proofs of concept.

Development of a parenting-related word-of-mouth information platform based on a token economy

iiba is a parenting review information platform based on a reputation economy and a token economy. Users can earn points by recording their movements and actions, and by sharing reviews from a parenting perspective, allowing them to attach real value to previously invisible parenting experiences and know-how, and companies can obtain data such as the trends and thoughts of parenting users, making it possible to build an effective platform for both parties. Accumulating data will create a map optimized for parenting users that shows only the best places, and we will conduct research and development to prove these concepts based on the hypothesis that this will contribute to behavioral design that encourages local consumption and economic development.

Childhood Dream Having a warm family
Influential People, Things, and Events Person: My husband, my child.
Thing: My part-time job at Uniqlo when I was a student.
Motivation, Goals, and Ideal World At the age of 20, she experienced a serious illness that put her in a life-or-death situation. Her outlook on life changed, and she decided to get married and have children early. She was shocked to find that child-rearing was even harder than when she was sick, and wanted to solve the problem somehow, which led her to start a business. She wants to eliminate solitary child-rearing, create a more enjoyable and happy child-rearing life than a difficult one, and brighten up Japan, where people are pessimistic about child-rearing due to the declining birthrate.
