Why doesn’t New Japan ever take stars from other companies in Japan.

I’ve been watching new japan since 2018 and Shingo is the only big star I’ve seen them poach. I feel like if new japan had done this more often then they would have much more stars. Imagine if they had poached guys like Kaito Kiyomiya, Shun Skywalker, KZY, Yamato, Tetsuya Endo, Yuki Ueno, Yuma Anzai and Kento Miyohara. Is it from a lack of trying or is it just wrestler not in njpw are a lot more loyal then wrestlers in the state.
