The 2018 Winter Olympics in PyeongChang have officially wrapped up and the 2020 Summer Olympics in Tokyo are next up for the world’s greatest athletes to congregate. In Tokyo, we’ll see advanced technology, some exciting new sports and even more exciting athletes looking to make their names on the world stage.

Here’s what you need to know about Tokyo 2020, the next Olympic Games.

This is the second time Tokyo has hosted the Olympics

Japan is no stranger to the Olympics, with the country having already hosted three Games with the 1964 Summer Olympics in Tokyo, the 1972 Winter Olympics in Sapporo and the 1998 Winter Olympics in Nagano. The 2020 Olympics will make Japan the third-most frequent Olympic host country in history with four, behind only the United States (nine) and France (six). We can expect to see plenty of venues from the 1964 Olympics used in 2020, as they make up a good chunk of Tokyo’s planned Heritage Zone. This is also the second of three straight Games hosted in Asia, with the PyeongChang Games in South Korea having just wrapped up and the 2022 Winter Olympics on tap in Beijing, China. So get ready to stay up until the wee hours of the morning again if you want to take in as much Olympic action as possible.

Tokyo beat out Istanbul and Madrid

The Japanese Olympic Committee had to beat out two of the biggest cities in Europe to land the 2020 Olympics. Tokyo won the first round of voting at the 125th IOC Session in 2013 with 42 votes, but didn’t win outright as it didn’t have a majority of the 94 votes.

Among the obstacles the Tokyo bid faced were worries about the Fukushima nuclear power plant disaster that was going on at the time, but concerns there have been appeased enough that Fukushima itself has been approved to host some baseball and softball games.

3. This is going to be a very expensive Olympics" data-reactid="44" style="margin-bottom: 1em; color: rgb(38, 40, 42); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; background-color: rgb(255, 255, 255);">3. This is going to be a very expensive Olympics

Tokyo organizers initially estimated the cost of the Olympics to run around 730 billion yen (around 6.8 billion dollars), but it’s become clear that was an ambitiously low total. More recent estimates put the cost for all Games-related expenses at around 2.16 trillion yen (around 20 billion dollars). While that is big chunk of change, it’s not even close to the money spent on the 2014 Winter Olympics in Sochi ($50 billion) or the 2008 Summer Olympics in Beijing ($40 billion).

4. The main Olympic Stadium initially looked like a turtle" data-reactid="46" style="margin-bottom: 1em; color: rgb(38, 40, 42); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; background-color: rgb(255, 255, 255);">4. The main Olympic Stadium initially looked like a turtle

While many 1964 venues are planned to be re-used, the Tokyo Olympic Stadium is being built from the ground up and its construction has been turbulent, to say the least. An initial design that had been criticized by one prominent architect for looking like a turtlewas eventually scrapped by prime minister Shinzo Abe after rising costs put it on pace to be the most expensive sports stadium in the world.

5.

The future is going to be on full display in Tokyo

A fleet of driverless cars. Facial recognition on a mass scale. Luggage-assistance robots at airports. A security network of tens of thousands of cameras and microphones. A MAN-MADE METEOR SHOWER.

6. Tokyo is the safest city in the world" data-reactid="77" style="margin-bottom: 1em;">6. Tokyo is the safest city in the world

While there were worries that the high rate of violent crimes in Rio de Janeiro would dampen tourism during the 2016 Olympics, there will be no such concerns in 2020. Tokyo has been consistently ranked as one of the safest cities in the world, if not the most safe. So feel free to party hard into the night, tourists.

7. The medals are going to be made of phones" data-reactid="79" style="margin-bottom: 1em;">7. The medals are going to be made of phones

You may or may not know this, but there is probably real, literal gold in your smartphone. It’s not a lot, just enough to act as an electrical conductor, but it’s there. The Tokyo 2020 organizers are planning to make use of that, starting an initiative for the Japanese population to e-cycle its old phones and computers so they can be mined for the precious metals used to make the medals for 2020. Environmental and cheap? Not bad, Tokyo.

8. There could be apocalyptic transport congestion " data-reactid="81" style="margin-bottom: 1em;">8. There could be apocalyptic transport congestion

Tokyo is known for plenty of good things. One thing it is not known for is uncrowded roads and trains. Public transport is already infamously packed on Tokyo. Add an Olympic audience and you have a problem. Japanese officials are aware of this and trying to combat it, doing things like relocating the biggest fish market in the world and introducing telework days to reduce the amount of commuters.

9. No, really, 3-on-3 basketball is now an Olympic sport" data-reactid="83" style="margin-bottom: 1em;">9. No, really, 3-on-3 basketball is now an Olympic sport

The IOC has dealt with its fair share of scandals and screw-ups in recent years, but they deserve applause on at least one thing: They’ve found a way to add more basketball to the Olympics. 3-on-3 basketball has been added to the Games and it is going to be glorious. We’re probably not going to see many of the NBA’s elite participating and the rules could be a little wonky, but come on, Olympic street ball. Feel the hype.

10. Baseball and softball make their return" data-reactid="85" style="margin-bottom: 1em;">10. Baseball and softball make their return

We still won’t see any MLB players taking part, but there’s a good chance we’ll see some stars of tomorrow. Just look at the baseball rosters from 2008, where you’ll find future MLB All-Stars Stephen Strasburg, Jake Arrieta, Yu Darvish and Dexter Fowler.

The IOC sent out a clear signal that it’s interested in a more youthful viewership with all of its new sports. In addition to skateboarding, we’ll also be seeing surfing, sport climbing and karate (duh, Japan) in the Games for the first time ever. Those are fun and all, but what if we combined them? I can’t be the only one that thinks a triathlon where you surf up to the coast, climb a beach-side cliff and fight someone at the top would be pretty cool. Don’t ask me how it would be scored.

Track enters the post-Usain Bolt era

With Usain Bolt now retired and enjoying life, the chase is on to replace the greatest sprinter of all time at the top of the medal stand in the 100-meter dash. With current 100-meter world champion Justin Gatlin still fighting father time at age 36, American hopes will likely rest on 21-year-old Christian Coleman. Another pair of big shoes to fill is located in the decathlon, where two-time gold medalist Ashton Eaton has retired.

Swimming enters the post-Michael Phelps era

The most decorated athlete in Olympic history has hung up his goggles. Unless he decides to put them back on again. Assuming Phelps is content with his retirement this time, the swimming world will prepare for its first Phelps-less Games since the 1996 Olympics in Atlanta. USA swimming will probably be just fine in the medal count even without Phelps, considering it still has 2017 world champions like Caeleb Dressel, Lilly King, Simone Manuel, Chase Kalisz and, of course…

Katie Ledecky hits Tokyo

Her name is Katie Ledecky and she is the most dominant swimmer of her generation. She might be the most dominant athlete of her generation. She made her debut in London as a 15-year-old in London and blew away the field in the 800m freestyle, then followed that up in Rio with four golds and a silver. Now poised to enter Tokyo as a 23-year-old and fully in her prime, she could compete in more events than ever.

The Olympics has added her best event to the program with the women’s 1500m freestyle and she has even started competing in individual medleys, smashing 2016 gold medalist Katinka Hosszu’s 400m NCAA record at the Pac-12 championships. We’ll see how many events Ledecky ends up competing in compared to her program of five in Rio, but get ready to see this woman everywhere, from medal podiums to Coke ads.

There’s no hiding it, there’s no forgetting it. Larry Nassar will spend the rest of his life in prison, but there is no doubt the staggering amount of victims left in his wake will cast a shadow over USA gymnastics for years, and especially in Tokyo. It’s a difficult topic, but important to remember as similar scandals are rooted out in other sports.

Team USA owns four of the six gold medals handed out in women’s soccer in Olympic history, but Rio represented a painful miss. The Americans fell in a quarterfinal shootout to Sweden, failing to medal in the Olympics for the first time in Olympic history. You can bet they’ll be working hard to avoid a similar result in 2020.
