or any other in Tokyo ?

i am 18
male
would be on a tourist visa
doesn't matter where
looking for anywhere from
40.000--50.000yen
i know that guest houses will most of the time give you a private room but other stuff is shared. is this a practical method for me to live in japan for 90 days? would also dedicate my 3 months to learning the language.

Check out Sakura house website. Sometimes the link to it is on the adverts on this forum. Sakura cater for short term stays and guesthouses with around the price range you are talking about

40-50k if you are sharing, you mean?
Your share?

Possible... but limited, I think...
could be pretty rough... :unsure:

What school will you be going to?
Often they have connections, if not special buildings of their own occasionally..

Not sure what the point was here, but to the OP:

The average apartment in Tokyo that I've seen runs between 10,000-20,000 JPY a month. Both apartments I've had were about 20,000. Keep in mind Tokyo is more expensive than other places.

It's also important to not that the outrageous million yen in initial rental fees and guarantor, etc is a bit of a thing of the past. I have yet to find a flat that asked for more than a deposit in the sum of one month's rent.

There are places of a wide array of prices. If you WISH to pay 40-50,000 a month for an apartment(ha, ha! Or a flatshare[why?]), you can easily do so.

One more piece of advice: You will have little luck searching English websites. You will have even greater luck searching locally when you arrive. None of the good places put up English websites. Only expensive tourist-minded/short-term/ignorant target audience ones do.

Cheers
