JETRO’s 10 September 2026 Harimanada case reviews frozen-oyster expansion into ASEAN. Export value rose from roughly ¥40 million before support to ¥980 million in its final support year. The unspecified support period must not be presented as growth within 2026 alone.
The Himeji processor mainly served Japan with locally landed oysters. Winter-concentrated demand created a need to smooth sales and widen regional oyster growers’ outlets. Producer relationships and stable procurement supported its overseas initiative.
Harimanada already had Proton freezing equipment. Product design then addressed restaurant practice: domestic packs of ten became packs of twelve to match menus selling oysters by the dozen. The case describes waste reduction and operating efficiency as the proposition.
Japanese export traders sharing the product concept were assigned different countries, drawing on their respective channels. The source records expanded business in Singapore, Thailand, Malaysia, Vietnam and the Philippines.
Promotional material explained thawing, cooking, freshness retention, low waste, monitoring and stable supply. It presented practical adoption benefits rather than taste alone. The case does not supply individual waste-rate data for recalculation here.
The reported export-value comparison is approximately 24.5-fold, not profit or one restaurant’s purchases. Higher demand created a new raw-material sourcing challenge. Harimanada was expanding collection points while stressing quality standards and customer trust.
