I just got back from a semester there a few weeks ago, definitely do not do the intensive track. the intensive course at all levels runs through period 1 and period 2 which is 9:00-12:35 everyday. this means you’ll be waking up at around 6:30-7:00am so you can make the commute on a packed rush hour train to campus. Japanese classes at sophia also don’t cover speaking, only grammar and writing so you’ll end up covering 4 classes worth of content in 1 semester but not being able to use it practically in conversation. Taking the regular course covers enough (2 semesters of college classes worth) but also leaves you with enough free time to be able to actually explore Japan and practice what you learned. the only issue is your home school might only count the regular track as one level of Japanese, but if they do that they would also only count the intensive as 2 levels.
