In Tokyo Bay, there are a collection of artificial islands that were built for defensive purposes back in 1853. Then in the 1950s and onward major landfills were conducted to create the modern shape of Odaiba. During the economic boom of the 1980s many futuristic buildings were constructed, however development halted in the early 1990s when the bubble burst. Later on, hotels, shopping malls and the Fuji Television headquarters established themselves in Odaiba. Since then Odaiba has become an amusement location attracting tourists and locals to their establishments. The convenient Yurikamome train travels all over Odaiba and offers a special day ticket for unlimited rides on the line.
Once you have purchased a day pass for the Yurikamome line then you are ready to begin your adventures in Odaiba. First stop to consider is the National Museum of Emerging Science and Innovation or most commonly known as Miraikan. It is one of the few places where you can see a robot and interact with it. ASIMO demonstrations happen at different times and is worth the visit. There are a few other interactive exhibits, but if your goal was just to see ASIMO then make your way to another area of Odaiba for some more fun.
Depending on the experience you are looking for, here are a few options you can choose to take. For family friendly fun, Decks is a great place to go. Not only are there food and shopping options, but they have a Ninja Trick Art Museum, Legoland Discovery Center, and Madam Tussauds Wax Museum in one building. Not too far from there, you can find Joypolis, which is an indoor amusement park. The amusement park is by SEGA, so there will be plenty of virtual reality attractions to try out.
Another place of interest is targeted towards Gundam fans. DiverCity is another shopping complex, but outside the establishment is a life size Gundam. The old RX-78 was replaced by the new RX-0 Unicorn Gundam, which debuted in September 2017. Throughout the day the Gundam transforms between unicorn and destroy mode. It is a sight that will make any Gundam fan happy. At night the armor remains illuminated from 7:30 pm to 9:30 pm. Inside DiverCity on the 7th floor is the Gundam Base Tokyo, which focuses on everything related to Gundam models.
Near Aomi Station on the Yurikamome line is an area known as Palette Town. There you can head over to Toyota Mega Web, which showcases the latest cars and technology of the Toyota brand. Then shop in Venus Fort, where it looks like a European town or something similar to the Venetian in Las Vegas without the gondola. One of the largest ferris wheels in the world can be found in Palette Town. From the ferris wheel you are afforded great views of Tokyo Bay and Odaiba. Sometimes on clear winter days you might be lucky enough to see Mt. Fuji in the distance.
For those looking to go sightseeing in Odaiba then there are a few places to visit. The Fuji TV headquarters building has a spherical observation room known as Hachitama. It is close to Daiba station and has a 270-degree view of the area. From Hachitama, there is an unobstructed view of the Rainbow Bridge, which is illuminated at night. Near the Fuji TV headquarters, there is a replica of the Statue of Liberty. It was meant to be a temporary display, but the popularity of the statue allowed it to become a permanent fixture with Rainbow Bridge in the background.
