One of the most famous local specifically in Shizuoka prefecture is Sakura-ebi(桜エビ)shrimp.
The shrimp is only caught in this region between Spring and Autumn. I went there to eat some nice local dishs using the shrimp(^_^)
The early bloomer of sakura is quite different from ordinary one which blooms around April. this early bloomer is flowering late January to March.
If you think of traveling in Japan, here is a must visit(^o^)
