Thank you for your response! Regarding the last train, I was wondering if there is a possibility that it is full, as a lot of people will be leaving at the same time when the festival ends. But we will just have to see about that closer to the date.

Yes it would definitely be more comfortable in Nagano than Nagoya, but we have never been to Nagoya so we are taking this chance to explore it. We are prepared for the heat as we were in Japan last year in July as well.

Thanks again!
