About JCB Credit Card Investment Customers can use various cards from the personal-use 'JCB Original Series' issued by JCB, and will receive 'J-POINT※1' returns based on the amount accumulated via credit card.

※1 J-POINT is a point service where you earn 1 point for every 200 yen spent in total on your JCB card, which can be used for shopping at physical stores and online. It was reborn from Oki Doki points in January 2026. ※2 Applies to 'JCB Original Series' cards issued by JCB (excluding corporate and family cards). ※3 J-POINTs will be awarded based on the redemption rate relative to the accumulation amount. J-POINTs can be used directly for shopping at physical stores and online, with 1 point worth up to 1 yen. Please check here for details (https://www.jcb.co.jp/point/index.html). ※4 The qualifying monthly usage amount applies only to shopping usage other than credit card investment. Note that certain expenditures not eligible for J-POINT accumulation, such as various annual fees, shopping revolving/installment/skipped payment fees, cash advance usage, and electronic money charges, are not included in the calculation. ※5 For every 200 yen of investment, standard cards are awarded up to 1 J-POINT, and premium cards are awarded up to 2 J-POINTS. ※6 The available accumulation amount may vary depending on the fund. ※7 Eligible funds exclude some options, in addition to foreign currency-denominated MMFs.
