Koshigoe Beach in Kamakura will be hosting the Nippon Craft Beer Festival in Shonan on July 11 and 12. Over 50 different beers will be on offer, with many local brewers participating as well. Entrance fee includes 10 drink tickets and advance tickets are available.
Unfortunately, the official website is only in Japanese, but tickets can be purchased through Lawson, Ticket Pia, and e+, so getting hold of advance tickets should not prove too difficult. Tickets are also available at the sight, if crowds permit.
Dates: July 9, 10 11am-4pm
Tickets: Advance ¥3900, On the Day ¥4500
Address: Beach house Asia Map
