Nihonshu (popularly known as saké outside Japan) has been enjoying something of a revival recently.
This event, which has been held since 2014, takes place along the pedestrian-only Kanamono Dori near the South Exit of JR Kanda Station (the venue has moved from Kanda Myojin Shrine).
Update: In 2017, the Nihonshu Festival will not be held. It is expected to take place again in 2018.To prevent the spread of COVID-19, many events have been canceled. Always check official sites before heading to an event.
