Cambridge: Can I take a year out mid-degree (undergrad) to study abroad?

I have an offer for PBS at Cambridge, which does not officially have an option to study abroad (I think the only courses with a study abroad year included are like the language courses, etc). However, I really want to study abroad and was wondering if it would be possible for me to take a year out between 2nd year and 3rd year or something to arrange my own study abroad?
I'm aware that this is probably quite difficult to do without the connections of a university-organised study abroad but yeah.
Just wondering if anyone has done this / something similar before and if it's possible

There's no value in this. It isn't 'Study Abroad' if it isn't part of your degree, it's just doing some study overseas. If you want to do some study overseas, take a Gap year before or after your degree.

Hiya yeah I just want to experience studying overseas, it's not necessary for my degree by any means. I guess I can just go after my degree, but I kind of wanted to go at the same timing as other people in my year. It's a bit complicated but I want to go to a uni in Japan:
Me: gap year + 3 year degree
People my age in Japan: 4 year degree
If I go after my degree it won't be with my cohort year group, if that makes sense.
Obviously it's not that big of a deal to go afterwards, but I was just wondering if going during my degree would also mean I could get some sort of help from the uni.

If there isn't a formal bilateral agreement with the receiving university and your university for students on your course, I can't see how you would get any specific support from your uni generally speaking outside of perhaps small travel awards/grants. Colleges also sometimes have small travel awards but this won't come close to paying the tuition fees or your living arrangements there (or even probably the full cost of your flights).
Also your "cohort year group" means nothing - people join uni at all ages, and since essentially nobody in your course is likely to be doing this it's not as if you'd know any of them. Also usually AMES year abroad students go in year 2 or 3 of 4 anyway I believe. Uni isn't school, you're not segregated by age.
To study at a uni in Japan you would need a high level of proficiency in Japanese, at least the equivalent of intensive first year language degree study (i.e. equivalent to more than half a year of credits typically) or two years of normal language degree preparation. I doubt as a non-language degree student you would get sufficient preparation in that time to do well on the JLPT.
Although it's worth noting if you wanted to take some language classes outside of your degree, these are offered by the language centre at Cambridge (you have to pay for these but I believe it's discounted for existing students - some colleges may provide some support towards this potentially as well...?).
There might be shorter programmes running in the summer(s) at Japanese universities where you can study language immersively, which may be more appropriate and may be less expensive while still giving you some of that experience.

I see, thank you. I've heard from someone else who studied abroad after their degree that Cambridge is quite closed-off and unhelpful with organising anything study abroad related. I guess this was another reason why I wanted to apply to courses with a study abroad sandwich year included because the tuition fees are limited to around max. 1.2k to your home uni with no tuition fees paid to the receiving university.
I'm actually japanese so the language is no issue, the reason why i want to go to uni in japan is more about wanting to experience what it would be like to be a student in my home country.
thank you for all your advice!
