Awamori Festival at Tocho

Get a taste of Okinawa high above the city at this one-night party dedicated to awamori, the southern islands' signature punchy liquor. 13 distilleries will be showing off their products, including some rare 30-year-old stuff, at the Tokyo Metropolitan Government Building's 45th-floor observatories. The ticket price includes all-you-cand-drink booze and an appetiser buffet, while music performances will also take place. If you're new to awamori, now's the time for some serious study.
