This is a free tour for everyone but you need to book in advance. It is awesome. You can visit places people cannot enter normal. You can also get souvenirs like a clear file with the ANA mark on it. One of my friends is a big fan of the airplane and I went here with him, but I myself had a great time. I am sure that even you have no interest in airplanes or something related to ANA, you would have nice time. The explanation is interesting and you might feel you would like to share what you learned to your friends and family.
