Who is the parent company of bitFlyer?

I understand that bitFlyer is a prominent cryptocurrency exchange platform, but I'm curious about its ownership structure. Could you please clarify who the parent company of bitFlyer is? I'm interested in understanding the corporate hierarchy and any potential affiliations that might influence the exchange's operations and decision-making processes. Additionally, I'm wondering if the parent company has any notable investments or expertise in the finance or technology sectors that could potentially benefit bitFlyer.
