HF recruiting at Booth MBA with no work exp but incredible technical skills/knowledge?

You can try, but I would also absolutely recruit for IB summer associate positions as a backup option. This would come handy in showing you have acquired some finance skills when you go recruit for full time HF positions.

It's worth a shot, but realistically, it'll be very hard to get looks from 'top' SMs / pods, which have few spots and plenty of candidates who are just as 'incredible' technically and have blue-chip backgrounds. 

Respectfully your technical skills are probably nowhere near as good as you think they are… especially with a soft major and no FO experience. The belief that you will self-teach and learn at booth mba more than a kid with a finance degree that has been grinding 100+ hour weeks for 2 years at a top group/eb is pretty laughable. You should strongly consider IB recruiting, you will be more attractive to the buy-side after an ib stint and may get a visa out of it

As others have said, it's not a given you would succeed. I went to one of the big HF recruiting schools (Wharton / Columbia / Chicago) and there was a clear divide between those with blue chip finance experience and those without (and another divide between white & asian males and women & diversity hires) in terms of outcomes. Being international will hurt (even if your visa situation is simple to explain, its still a situation and most employers just don't want to figure it out, would rather hire an American) unless you read and write Japanese fluently (sounds like you do) and there's a PM looking for someone who can partially or completely cover Japanese stocks. That's actually not a huge leap of faith as I often see PMs looking for Japanese / Chinese / Korean speakers.  

Edit: also, you've given enough information to dox yourself so you should edit and/or delete this post.

This would be tough.  Prefer to hire from front office positions or those with front office experience

Why isn't the visa not an issue after an MBA? You are non-STEM and hence not eligible for CPT. The odds of getting an H1 visa are currently around 10%.

u sound autistic, tbh 

As long as you explicitly tell them you have incredible technical skills, you should be fine.
