Mitsui Sumitomo Trust Club Co., Ltd. (Representative Director: Nobuaki Yamaguchi), the issuer of the Diners Club Card, launched its official app service "HISTORY" on April 1, 2026. This service records members' journeys, likening them to jewels.
This service was born in response to the voices of long-time Diners Club patrons who expressed a desire to feel even more enjoyment in continuing to hold the card. Aiming to deepen the relationship with members, this is a unique Diners Club service that visualizes the journey with members, such as contract years and card usage, in the beautiful form of "jewels" and delivers it with messages.
■ What is HISTORY
"HISTORY" is a service where, upon reaching various milestones such as the anniversary of your card contract or when your cumulative spending amount reaches a certain figure, a special jewel commemorating that moment will be engraved in the member-exclusive jewel box within the official Diners Club app.
For example, on your first anniversary of enrollment, you will receive a "Green Zircon," and when your cumulative spending reaches 1 million yen, you will receive an "Aquamarine." Furthermore, if you spend 200,000 yen at fashion-related affiliated stores, you will receive an "Opal," and so on. Colorful jewels befitting the member's various actions will be presented.
Messages will accompany the jewel presentations, serving as an opportunity to reflect on the time Diners Club and its members have spent together. The collected jewels will beautifully adorn the journey with Diners Club within the original jewel box.
