Interview at a Catholic school in Tokyo

Hi all, hoping for some insight. I'm currently juggling a number of different teaching jobs including solo teaching at a junior-high/high school, teaching English at a college, school holiday English camps and private tutoring. I'm hoping to swap this for a single full time teaching position next academic year, and I've got an interview scheduled in Jan for a job which sounds ideal - full time, semi-international school, and teaching English literature as well as language, which is my academic background and first love.

The only thing that's deterring me is that it's a Catholic school, and I'm not sure exactly what that signifies in Japan. Western friends with a Catholic school background all have horror stories about abstinence only sex ed, creationism and anti-LGBT, pro-life messaging, and I wouldn't want to work anywhere that espoused those values in the guise of education.

On the other hand, I have two private students (siblings) who went to a Catholic junior high and high school, and they said most of the staff and students didn't identify as Catholic, and though they had to attend mass three times a year, and learn about Catholicism in ethics class, the influence was mostly cosmetic, and they went to the school because they/their parents thought it was the best place for them academically. I felt uncomfortable pressing them to say whether they were lectured about things like the topics mentioned above, but I do know from years of acquaintance that they're socially liberal, accepting, and open minded.

So basically, is the image of Catholic school that I have as a Westener very different from the reality in Japan? Or should I proceed with caution? Is there anything in particular it would be good for me to ask in the interview to suss this out?

Thanks in advance!
