おもしろいそうな日本
こんにちは。私の名前はアリサです。日本がに/へ行きたいですよ。※よ is a particle to emphasize. It's used when the speaker wants to inform the sentence to the hearer(reader) firmly. This is a usual self-introduction. The hearer(reader) has not said that you don't want to go to Japanese. So you don't have to use よ.
日本のぶんかと食べものはおもしろいそう(です)。そして、夏まつりは/も楽しそう(です)。※You can use も because there are the same in writing good points.
でも、日本は時々さむいですね。私は寒いのがきらい(です)。それでも、私がは行きたいです。
