[!note] Naming note This page was originally requested as a slot under the name “dock-financial,” but since no independent financial group entity called “Dock Financial Group” can be confirmed in Japan, the SoftBank group’s payment-agency subsidiary “SB Payment Service (SBPS)” is substituted instead. It is positioned as the operating-company anchor for the SoftBank group’s financial functions.
