A practical guide to building a regional brand through OEM using heirloom and Kyoto vegetables. We cover Kyoto Prefecture's 40 “Traditional Kyoto Vegetables,” certification programs for heirloom vegetables across Japan, the flow of turning them into processed goods—dried, frozen, powdered, furikake, seasonings—and real OEM cases including OYAOYA (upcycling in northern Kyoto), ZIGExN (novelties), and MA. From seasonality, yield, and handling of non-standard produce to 100 g small-lot prototyping and milling and cutting. We also handle rare vegetables from Okinawa and across Japan.

Product development that draws on “regional character” is drawing attention right now. Among these, foods made with heirloom vegetables andKyoto vegetableswin strong support in the gift market and as inbound-tourism products for their visual beauty and rarity. With inbound tourists on the rise, creating souvenirs with regional character can turn into a hit product in a specific area.

OEM manufacturing is an effective way to use these regional ingredients. By combining processing and preservation techniques for agricultural produce, you can move past the distribution constraints of seasonal and heirloom vegetables and supply highly distinctive products on a stable basis.

What are heirloom and Kyoto vegetables? | The appeal of vegetables rooted in a region

What are heirloom vegetables?

Heirloom vegetables are native varieties handed down in a region over many years. The Ministry of Agriculture, Forestry and Fisheries defines them as “varieties cultivated in the region before 1950,” ingredients deeply tied to the local climate and food culture.

Example:

Kaga renkon(Ishikawa Prefecture)

Kamo eggplant(Kyoto Prefecture)

Shima rakkyo(Okinawa Prefecture)

What Are Kyoto Vegetables

Kyoto vegetables are the collective term for heirloom vegetables long grown in Kyoto. Among them, Kyoto Prefecture's designated “Traditional Kyoto Vegetables” numbered 40 items as of 2024, known for their visual beauty and delicate flavor.

Points to watch in OEM manufacturing | Using heirloom vegetables

Heirloom vegetables carry value, but they also come with production hurdles such as unstable sourcing and high raw-material costs. Anticipating these is essential to a successful OEM project.

Key points to watch

Many are strongly seasonal
→ Drying, freezing, and powder processingyou need to build a system that can supply them stably.

Prices run higher than ordinary vegetables
→ Secure margins throughhigh-value-added product designsuch as gift use or health appeal.

Harvest volumes are limited, so lot adjustment is needed in advance
→ Heirloom vegetables often already have committed buyers, so lot adjustment must be arranged in advance.
