This small theme park is a short walk away from Yamashita Park in Yokohama. Tickets can be purchased online in advance, but during the week this isn't necessary. Tickets for entry and also the special viewing are both now available at the ticket booth. Buying tickets in advance gives a QR code that can be scanned at entry. The price of entry is 1650 yen and to get up to the top of the dock is an additional 3300 yen. The view from the top of the dock is to the side and behind, so honestly not the best views, but it is up close and personal so all the details an be seen. I wouldn't recommend paying extra if you aren't a die hard fan, since the view of the action is better from the stairs across the way and the Gundam Cafe. Upon entry, a small model is provided - a 1/200 scale RX-78F00, the same one present at the factory.
Every hour, the Gundam has a show and moves out of the dock, takes a few steps, kneels, stands back up, then points to the sky. It will then move back into the dock. This is spaced out over the hour and repeats. It moves slowly, but is very impressive to see in person.
There isn't all too much here to see besides the life sized Gundam - there is a small laboratory exhibit that shows the techniques used to develop and build the Gundam. It has a "VR" experience that shows the path a pilot would take into the Gundam cockpit - I didn't think it was too impressive, personally, but interesting to at least see. Besides that, there is a Gundam Cafe that offers excellent views of the Gundam. The drinks here were very good and refreshing, there is also an option to buy a drink in a themed, collectible plastic bottle. The food is expensive but also themed. There are a few concession stand locations, but only one serving popcorn (in a Haro themed container) was open during my visit. I'm not sure if the others open up at all.
The other highlight is a large Gundam Base store that offers exclusive models and goods exclusive to the location. The prices are good and the only goods I thought were overpriced were the clothing items - but that tends to be the case for all the Gundam Base stores.
For fans, this is a great experience, but for most people it might be a pass unless in the area, and even then only standard admission. I had a good time watching my childhood come alive.
