※I feel this sentence is unnatural. This may because you use the same verb"いく" twice. When I see "いきたい," I can think you cannot come to Japan but you want to come. I mean, I can interpret the sentence as "you wish you could come to Japan". Therefore the next fact that you going to come to Japan sounds a little weird. You had better just say"日本に7月にいきます。" or add another reason like "日本が好きなので(Because I like Japan)"
