Yonaguni is best known for hanazake è±é , literally "flower sake", a drink nowhere near as dainty as you might expect from the name: it's the local 60° awamori and tradition demands drinking it straight, without even an ice cube to ease the pain. The best known brand is Donan ã©ãªã and the other labels brewed on the island are Yonaguni ä¸é£å½ and Maifuna èå¯å, meaning 'clever person' in the local dialect. You can visit the breweries of all three in Sonai, sample a little, and learn about brewing methods. It's fairly steeply priced though, as a 600ml bottle of the stuff will set you back over ¥2000; and you need to add a few hundred yen if you want the traditional protective straw coat for your bottle. Cheaper and marginally less lethal 43° and 30° versions are also available.
