So regarding parks if you look over the last five years, our EBITDA or OCF and the park business has almost exactly doubled, so about $2.5 billion as the parks are about one-third of NBCUniversal, 30% of NBCUniversal. And when you have that kind of growth you're used to parks being a driver of the overall NBCUniversal growth profile, which they were not this quarter. A big part of it and Mike mentioned this in his introduction was Japan where we faced a number of headwinds and actually went backwards.
If you look out, I think the next big thing on the horizon is Nintendo. Nintendo based on our research is one of the biggest potential drivers of attendance that you could have of any kind of IP. It's up there with Harry Potter, which in some of our parks Harry potter drove incremental attendance of about two million people. So Nintendo is in very rarefied air. And the attraction that we're building in Osaka is spectacular.
From a creative standpoint it's really unbelievable and that opens sometime -- midyear this year and then we're going to bring it to Hollywood and we're going to bring it, obviously, in the fourth gate in Florida. So I think Nintendo is going to be potentially a big accelerator both in the Theme Park business. And then once you get into 2021, we've haven't talked about it maybe as much as we should.
The fact that we're opening a park in Beijing and the fact that the park is so spectacular from a design and creative standpoint, I think is going to generate a lot of growth. And then Brian mentioned in his introduction the fourth gate, which opens in 2023.
So when you look at the capital side of it, these are all high-return projects that all make a ton of business sense. And I think if you look over the next five years it's likely our Theme Park business is going to be a driver of growth. Maybe not quite as much as it has been in the last five years because the growth has been so phenomenal and we're getting to a bigger base now. But I would look at the parks business as a real opportunity for us. We still don't have the share that I think we deserve given the quality of the experience we're giving our guests and it's a lot of opportunity over the next five, 10, 20 years.
