Kokunai-seizō Wine (国内製造ワイン)
Wine bottled in Japan from imported juice — the legally distinct category from Nihon Wine
What It Is
Kokunai-seizō Wine (国内製造ワイン) — sometimes simplified to Kokunai Wine — is the Japanese legal category for wines bottled in Japan from inputs that include any of:
- Imported bulk wine
- Imported juice or concentrate
- Imported grapes
- Mixtures of imported and Japanese fruit (in any proportion)
The category was formalized as legally distinct from Nihon Wine (日本ワイン, "Japanese Wine") by the National Tax Agency’s wine labeling standard, effective 30 October 2018. Before 2018, wines in this category could be marketed somewhat ambiguously; after 2018, they must clearly carry the "Kokunai-seizō Wine" label, with foreign-origin disclosure on the back label.
Why the Distinction Matters
By volume, Kokunai-seizō Wine is much larger than Nihon Wine — most inexpensive Japanese-bottled supermarket wine sits here. The 2018 distinction matters because:
1. It protects the meaningful "Japanese Wine" category. Producers investing in Japanese vineyards can claim "Nihon Wine" without competing against bottled-in-Japan foreign wine using the same label.
2. It enables informed buying. Consumers can distinguish Yamanashi-grown Koshu from Chilean-bulk-wine bottled in Japan, by reading the label.
3. It is the foundation of GI claims. Geographical Indications (GI Yamanashi, GI Hokkaido, etc.) all build on the underlying Nihon Wine definition — so the legal scaffolding here matters.
Practical Reading
The back label tells the story. If it says:
- 日本ワイン (Nihon Wine) — fully Japanese, label-protected
- 国内製造ワイン (Kokunai-seizō Wine) — bottled in Japan, foreign or mixed sourcing, with country-of-origin disclosure
If neither term appears clearly, the wine likely was bottled before October 2018 or is mislabeled.

Why It Matters
The Kokunai/Nihon distinction is the single most important consumer-protection development in modern Japanese wine. For overseas importers — including D-I Wine — the practical consequence is that any wine described as "Japanese" must be Nihon Wine; Kokunai-seizō Wine sold abroad would be misleading. The distinction is enforced strictly within Japan and is becoming the export-market norm.
