Calbee Shrimp flavored Chips are an (extruded?) baked savory snack with a mild taste of fresh shrimp.
Calbee North America describes their Shrimp Chips as:
Accented by a mild taste of fresh shrimp and sprinkled with a pinch of salt, Shrimp Chips are a fusion of traditional Japanese flavors and retro-modern cool. Flavors available include Classic Original, Wasabi and Hot Garlic.
Outside of North America - and including Japan - different versions of this product are available as Shrimp Crackeer "Kappa Ebisen", which is the first snack food introduced in Japan in 1964.
