A concept so unique it feels a bit strange to even call it a "museum," visionary digital art collective teamLab's Borderless can be found in Odaiba, inside the Mori Building Digital Art Museum. One of Tokyo's hottest new tourist attractions, the fact that it's packed with visitors isn't enough to diminish the excitement and wonder the first time you enter this psychedelic, dreamlike world.

The vast space is organized in such a way that there are no physical barriers between its various exhibits, which allows for free exploration of its many visual wonders. Some 520 computers and 470 projectors are utilized (along with countless LEDs and other technological wizardry) to create an environment beyond the bounds of even the most creative imaginations.

Most of the exhibits are interactive as well, with drawings projected on walls, whales floating under the feet of passers-by, colorful slides and balls that react to touch and more. For those who find themselves overstimulated, there are also quiet rooms and a café where visitors can relax. This is a one-of-a-kind experience that anyone who visits Tokyo should indulge in. But plan ahead—the museum is insanely popular, and tickets are available online but sell out fast!

Speaking of Odaiba, anyone who knows better will tell you that the best way to avoid the crowded buses and trains is to take one of the unique water buses that shuttle up and down the Sumida River.

They conveniently run every 20 minutes, and have several different areas from which one can board. They also offer some seriously gorgeous views of the surrounding city, the river itself and the Rainbow Bridge that spans Tokyo bay.

Keiba, or "horse racing," is an unexpected event to find in Tokyo. The Ohi Racecourse has something to offer both casual visitors and racing connoisseurs, with a picnic area opposite the broadcast screens and tracks, classic bleacher seating and indoor seating as well.

Located inside the on site restaurant The Diamond Turn, the private seating is especially exciting. There are screens with which to track the results of each race, as well as windows directly overlooking the track. There's nothing quite like the energy that explodes in the room after a neck and neck race, cries of disappointment and defeat mingled with elation at the results. The restaurant also offers a wide variety of delightful refreshments, and access to a delicious buffet.

Perhaps the best place in Tokyo to get a view of the city, the Tokyo Metropolitan Government No. 1 Building has two observatory decks (both north and south, though the south is currently undergoing rennovations for a reopen in spring, 2019) that tower 202 meters (about 660 feet) above the ground, and are completely free to enter. Watching the city stretch as far as the eye can see in either direction is truly awe-inspiring, especially at night when Tokyo positively sparkles from the bright lights of its towering skyline.
