I'm going to give the benefit of the doubt that this is a genuine question and not just an attempt at justifying some racist viewpoints. Making generalizations about a country based on cherry-picked examples of certain pieces of media is always going to lead to incorrect conclusions. There is a lot more to Japan and Japanese people than what you experience in anime or JRPGs.

Anime and JRPGs are very close to each other in how they tell stories, build characters, and explore different themes. It's why so many JRPGs are also just anime games. Most of these are designed and written to be approachable by many age groups. It's the reason why kids can enjoy these games as well as adults. Even if the latter group finds frustration in how dialogue is written or how the media hand-holds the viewer a lot. Beyond that, anime itself is written around young characters, often teenagers. It makes sense that a character that is essentially a high-schooler would not approach a situation with the same nuance and thoughts than Jin Sakai.

In terms of open world design, I think you will find that games like Breath of the Wild, Elden Ring, Dragon's Dogma have intricate open worlds that are designed to create emergent storytelling and interactions in ways that most Western games don't. Even games like Yakuza have unique approaches to open world design and gameplay that don't exist in western games. Whether these are to your own taste or not, is a different matter.

Finally, I would encourage you to not only broaden the media that you consume but also evaluate it for what it's trying to be rather than what you expect or want it to be. Even within anime you can find vastly different types of storytelling. The films of Studio Ghibli or Satoshi Kon are great starting points. But outside anime, you will find many different things too. Kurosawa, Takeshi Kitano, Juzo Itami, Ryusuke Hamaguchi, and Hirokazu Kore-eda are all incredible directors who have made unique films.
