Japan's longest-running internet-only bank (operational since June 2001) — predates Rakuten Bank's eBank acquisition and tied with SBI Sumishin for first-net-bank tenure. The structural specificity is multi-currency forex strength: foreign-currency deposit accounts in 12+ currencies plus retail FX margin trading, the deepest retail-FX product among Japanese chartered net banks. Wholly-owned subsidiary of Sony Financial Group, in turn part of Sony Group Corporation (TYO: 6758).
