Is bitFlyer regulated?

I'm curious to know, is bitFlyer, the popular cryptocurrency exchange platform, regulated by any governing body or authority? It's important for investors and traders alike to understand the level of oversight and protection that their funds and transactions receive when using such a platform. Can you provide some clarity on this matter, outlining the specific regulations or licenses that bitFlyer may hold, as well as any additional measures they take to ensure the safety and security of their users' funds?
