The Hamburger Boys are a pop band from Hokkaido. They got together to make fun, catchy songs that promote how great Hokkaido, Japan is. One of their popular songs is What’s Going Onion… obviously a play on the English expression “What’s going on” while still talking about how great Hokkaido onions are. The song specifically promotes the Sarasara Gold type of onion which is grown in Hokkaido and especially high in Quercetin.
Here’s the video, enjoy!
