This isn't just any old golf game, it's actually from Clap Hanz - the developer behind the PlayStation series, Everybody's Golf / Hot Shots Golf.
While there was no mention of it in the local broadcast, the game has also been released and it's available here in the west for $19.99 / £17.59 on the Switch eShop. It was previously released on the Apple Arcade service in 2021 as Clap Hanz Golf.
Here's a bit more about it from Nintendo's website:
