Hello Rio Lee~~! Long time no see!! >_<
How've you been doing? I hope everything is going well for you.
As for your question on price for the "student commuter pass" or
tsuugaku teiki, maybe you could try
Ekinet.
It's in Japanese only, but hope you can use it...
You select the a)starting day, b)the kind of pass you want(ie, high school student/college student), c)departing point(station name) and d)destination(arriving station name) and search, then you can get the fare for 1 month, 3 months and 6 months respectively.
But please note that this works only for the
JR lines, but not available for buses, or private railroads. (how useless, eh)
But still, it may give you some idea how much discount you can get. According to Ekinet, price for 1 month commuting pass from Hachiouji to Tokyo for instance:
-High school student: 9,340yen
-University/College student: 10,380yen
-Regular price(Adult):21,330yen
Also, I advise you first to ask your Senmon Gakkou if they are a designated school by JR/other railroads, because JR doesn't issue the school pass to some Senmon Gakkou students, depending on how many classes/hours per year you take. (Well, I believe most schools are designated, but just to be safe.)
When you purchase the commuting pass for student, you'd need 2 kinds of certificates issued by your school(student ID card and a paper to certify your departure point and destination, that is), so you could ask your school staff if they issue those certificates if they do not understand what I mean by "designated". Or, simply, "tsuugaku teiki wa tsukaemasuka?" in Japanese.
I understand it's a hard decision whether to live close to the school(pay more for the rent and less for transportation) or to live far away(pay less for the rent and more for transportation). But riding on a packed train during rush hour would be a pain if you're used to going to school by bike. ^^;
Anyway, hope that helps,
Cue
