How do I manage my Tokyo expenses?!

Hey there! I'm coming to Tokyo soon, and I'm a lot lot troubled by how my life's gonna fare. I need to pay ¥65k as rent per month, and I'll have only ¥55k remaining to cover all other things including food and other necessities (because that's about what my stipend allows). I know it's too ambitious to be able to think of managing life in Tokyo in ¥120k, but I can't do anything about it. Do you folks have some suggestions regarding the same? I'd honestly love some genuine suggestions! Thanks in advance!
