Mixed profile — check regulation and conditions before depositing.
Crucially, KOSEI SECURITIES CO., LTD. is regulated by FSA, including at least one tier-1 regulator.

No complaints are currently on record. Overall, KOSEI SECURITIES CO., LTD. has a mixed profile: check its regulation and conditions carefully before depositing.

How is the KOSEI SECURITIES CO., LTD. trust score calculated?

What does "offshore regulated" mean?
It means the broker's licence comes from a jurisdiction with lighter requirements than tier-1 regulators like the FCA or ASIC. There's usually no compensation scheme, so recovering funds can be difficult if the broker fails.
Can I withdraw funds easily from KOSEI SECURITIES CO., LTD.?
KOSEI SECURITIES CO., LTD. doesn't publish detailed withdrawal terms, so we can't verify processing times or fees. Test with a small amount first and document every transaction.
