Yuki Tsubaki Uonuma Koshihikari White Rice 11 lb (5 kg) — Ultra‑Premium Small‑Batch, Sushi‑Grade

Yuki Tsubaki Uonuma Koshihikari is an ultra-premium, exceptionally rare Japanese white rice grown in Niigata and sold as a single 11‑pound (5 kg) pack.

This Koshihikari comes from Echigo Yukazaki in Uonuma, Niigata Prefecture — a region celebrated in Japan for ideal rice-growing climate and mineral-rich soils. Harvested and managed under special cultivation standards, this lot represents less than 0.003% of all Koshihikari produced in Uonuma and is chosen by top restaurants and rice competitions for its texture, aroma, and balanced sweetness.

Why is this Yuki Tsubaki Koshihikari considered so rare and premium?

This rice is designated from a specific micro-region and follows strict cultivation and selection processes that greatly limit yield. The combination of terroir, selective harvesting, and small-batch handling yields grains with consistent polish, translucence, and flavor preferred by chefs.

• Grown in Echigo Yukazaki, Uonuma — premium rice terroir.
• Special cultivation protocols and limited harvests.
• Selected and exported in small quantities, under 0.003% of Uonuma Koshihikari.
• Favored by high-end establishments and rice contests in Japan.

How should I cook this Koshihikari for the best texture?

To highlight the rice's natural sweetness and glossy texture, rinse gently until the water runs clear, soak briefly, and use precise water ratios for your cooker. Shorter or longer soaking adjusts chew; follow these steps for consistent results.

• Rinse 3–4 times until rinse water is clear.
• Soak 20–30 minutes at room temperature before cooking.
• Use 1:1.05–1.1 rice-to-water ratio for a sticky yet distinct grain.
• Steam or rest 10–15 minutes after cooking for full flavor bloom.

What dishes show this rice at its best?

This Koshihikari's polished shine, firm-yet-tender bite, and subtle sweetness make it ideal for dishes that rely on rice quality: nigiri, sushi bowls, premium donburi, and simple steamed-rice presentations where texture matters most.

• Premium nigiri and sushi — rice holds shape and texture.
• Deluxe donburi and kaiseki courses — complements delicate toppings.
• Plain steamed rice — showcases aroma and natural sweetness.
• Rice pairings with fine Japanese condiments and broths.

How should I store and handle this rice to preserve quality?

Because this is a small-batch, high-grade product, protect it from moisture, heat, and odors. Proper storage preserves aroma and texture so each serving maintains the character that earned the rice its premium status.

• Store in a cool, dry place away from direct sunlight.
• Keep sealed or transfer to an airtight container after opening.
• Use within several months for peak aroma; refrigerate in warm climates.
• Avoid strong-smelling foods nearby to prevent flavor contamination.

Who is this for? Yuki Tsubaki Uonuma Koshihikari is aimed at home cooks and culinary professionals who value the nuance of single-origin rice — restaurateurs, sushi chefs, gourmets, and anyone who prefers premium Japanese staples for special meals. If you appreciate small-batch provenance, precise texture, and rice that performs beautifully in refined Japanese dishes, this 11‑pound import from Niigata delivers a clear step up from standard supermarket rice.
