TL;DR

A major domestic credit-card company. Established 1951 年 as Midoriya Credit → 1980 Seibu Credit → renamed Credit Saison in 1989 . Against a backdrop of industry-top-tier card issuance with over 4000 万 cumulative members, it is a non-bank that earns along 4 axes: US American Express partnership premium, the Eikyu-Fumetsu (永久不滅) loyalty-point ecosystem, Saison Asset Management cross-selling, and Indian consumer finance (Kisetsu Saison Finance) overseas expansion. After the breakup of the old Saison Group, it was repositioned as an independent card company within the Mizuho FG orbit (mizuho-fg affiliated). Securities code TSE PRIME 8253.

MUJI Card / Lawson Ponta Plus, etc.: distribution / retail partnerships

Eikyu-Fumetsu loyalty-point ecosystem

A proprietary program that pioneered “points that never expire” ahead of the industry. Long-term-holding motivation → continued card use → improved customer LTV loop. Points can also be diverted to investment-trust purchases and management, building an asset-management funnel through point × Saison Asset Management cross-selling.

A separate line from proprietary Amex (American Express Japan)

The combination of the Seibu / PARCO commercial-flow legacy + Amex premium + Eikyu-Fumetsu points is unique
