Credit Saison and Mitsui Fudosan Group's Tokyo Dome Announce Partnership: "Tokyo Dome City Card 《Saison》" to Launch in Late June 2026, Making Watching Games and Shopping More Fun and Special

Credit Saison Co., Ltd. (Headquarters: Toshima-ku, Tokyo; Representative Director, President and COO: Katsumi Mizuno; hereinafter "Credit Saison") and Tokyo Dome Corporation (Headquarters: Bunkyo-ku, Tokyo; President and COO: Tsutomu Nagaoka; hereinafter "Tokyo Dome") will begin accepting applications for the co-branded credit card "Tokyo Dome City Card 《Saison》" in late June 2026.

This new credit card is designed to enhance the entertainment experience at Tokyo Dome City, including professional baseball games, while also connecting to daily shopping and service usage.

Additionally, Tokyo Dome will revamp its point service for Tokyo Dome Group facilities, introducing "Mitsui Shopping Park Points" starting Saturday, August 1, 2026.

Customers will be able to earn two types of points—Mitsui Shopping Park Points and Eikyufumetsu (Permanent) Points—when shopping or using services at Tokyo Dome Group facilities.

Moving forward, Credit Saison and Tokyo Dome will continue to combine their respective strengths to deliver exciting experiences that make time spent at Tokyo Dome Group facilities special for all members.

Background

Through the Mitsui Shopping Park Card 《Saison》, Credit Saison has provided value such as point services and various benefits to 4.7 million customers (as of the end of December 2025) who use Mitsui Fudosan Group's commercial facilities.

Furthermore, on July 14, 2025 (Monday), Credit Saison hosted the "SAISON presents Special Nighter" at Tokyo Dome (sponsored by the Saitama Seibu Lions), working to build connections with the community and fans through sports promotion.

Tokyo Dome City is an urban entertainment hub offering diverse experiences, including large-scale events such as professional baseball and concerts, as well as an amusement park, hotels, spas, and commercial facilities.

The "Tokyo Dome City Card 《Saison》" is a co-branded credit card that allows users to enjoy entertainment experiences like baseball games and events at Tokyo Dome City at a better value, while also offering convenient and advantageous benefits for daily use, such as shopping at Mitsui Shopping Park Point-eligible facilities nationwide.
Customers who already hold a Mitsui Shopping Park Card 《Saison》 will also be able to use the benefits at Tokyo Dome City.

Regarding the Revamp of Tokyo Dome Group's Point Service

The point service operated by the Tokyo Dome Group will be updated from the existing "TD Points" to "Mitsui Shopping Park Points." Starting Saturday, August 1, 2026, it will be possible to earn and use "Mitsui Shopping Park Points" at eligible facilities*, including LaQua, Tokyo Dome City Attractions, and Tokyo Dome Hotel.

The "Tokyo Dome City Card 《Saison》," scheduled to launch in late June 2026, will be deployed as an advantageous and convenient payment service that allows users to earn both Eikyufumetsu Points and Mitsui Shopping Park Points in conjunction with the start of this new point service.
