Oh, I vaguely remember watching this with my family in 多摩六都科学館 (Tama Rokuto Kagakukan) in Tokyo, around 2005. I forgot the plot and how the anime looked like, but I remember sitting next to my father in a dome theater. I also found the following link, which says that the movie was presented from 2005/11/1 to 2006/3/31: https://web.archive.org/web/20051106085124/https://www.tamarokuto.or.jp/zen.html

After searching Google, it seems that the movie was presented in some science museums: https://space-park.jp/events/news/2005/0808/ http://norimi.blog45.fc2.com/blog-entry-184.html
