Most people flatten an entire island culture into the word Japanese and never learn what got lost in the folding — a different language, a different music, a completely different plate of food. Once a year that distinction gets put out in the open air in Balboa Park.
You will not find ryukyu soba or goya champuru at your neighborhood Japanese restaurant, and you certainly will not find taco rice, which is what happens when an American base and an island kitchen negotiate. The music runs on the sanshin, a three-stringed instrument you can pick out of any recording instantly — obviously, immediately, not the mainland.
The Eisa dances are the center of it. Drum-based folk dance performed by community groups in traditional dress, rhythmically complex, with the martial arts history sitting visible inside every movement.
Bring anyone curious about the threads running underneath Japanese American history. This is the day one of them surfaces in daylight.
