Interested In Attending a Language School In Japan For 6 Months

Hello, recently ive been thinking of traveling abroad after college and living somewhere else for a change. I'm currently thinking about different options and one of those is Japan. I have a lot of questions on how all of this works and wanted to make a post to ask all of you how your experience has been and if you have done something similar to what I'm looking to do. I'll list off the questions below and if anyone could answer them or some of them I would highly appreciate it! (I am from the US if that changes anything) 1 - How difficult is the Visa process? Right now im looking at a website called "gogo nihon" which seems to handle this. 2 - What are these language schools like? So far I've read online that they only start during certain months, my plan currently would be to shoot for sometime next summer. 3 - Are there extra fees for school? From the website I mentioned earlier the schools listed seem to have a set price, are there any other expenses? 4 - How does housing work? I've always heard finding housing as a foreigner is difficult, however on the go go nihon website they seem to help with this process, is it better to go through them or someone else? 5 - How much would you say it cost to live each day? I know this can change drastically from person to person but by the end of your stay how much did it cost you? 6 - Overall how was your experience? I'd love to hear how your trip was and if there is anything I should know about 7 - Are there any other things I should know or be looking into? I wanna make sure I'm prepared and not go in totally blind. Thank you for reading, any help is very much appreciated
