That's because what you see on the OTC for Nintendo is an Advanced Depository Receipt, and not the stock directly. It's a Tier 1 ADR, so there are no reporting requirements for it in the US, highly speculative, and OTC Markets would put up a yield sign since a potential investor would have to track down the business performance information themselves (easy to find on google). That's very different from a US based stinky pink scam stock...
