Tokunoshima is a relatively unknown gem that makes up part of the Amami Islands chain, and it's renowned for its pristine natural beauty, rich cultural heritage, and unique regional cuisine. If you'd like to experience a slice of this in Tokyo, be sure to check out the Tokunoshima Tourism and Product Fair at Yoyogi Park.
The fair is set to include a variety of cultural performances including sanshin music (a traditional stringed instrument from Okinawa and the Amami Islands region), delicious regional cuisine, and information about traveling to this part of Japan.
Admission to the event itself is free, but do bring yen if you plan on purchasing food or drink.
