Thank you so much for taking the time out to help me.

What should the particle be for 旅かんをとまります and 日本語がならいたい？

Also, for しておかなくちゃ, we just learned how to say doing something in preparation for which is the verb おきる. On the requirements for the essay, one of the things we have to write in the essay is: What you will do in preparation for the trip (using ~ておきます、~ておかなくちゃ
いけません、~ておくつもりです etc.) <<That is one of the exact sentences written in the requirements. So I assume that it is okay to write しておかなくちゃ.

For あきはばらで買い 物に行きます, I thought that the particle で was used to describe a place of action. And I would be shopping in Akihabara.

Instead of 日本レストランで食べるつもりです, how would I say: I plan to eat at restaurants in Japan? Instead of in Japanese restaurants.

つ ぎに (next) is one of the transitions she listed that we could use in the essay.
