About Omi Beef
Omi Beef is a premium Wagyu brand certified by the Omi Beef Production and Distribution Promotion Council for Japanese Black cattle raised longest within Shiga Prefecture. Presented as tribute to the Tokugawa shogunate since the Edo period, it holds the longest history of any Wagyu brand — nearly 400 years. The Omi Beef name became established in the Meiji era, when it earned its place among the top-tier butchers of Tokyo and Kyoto. Registered as GI No. 56 by MAFF in December 2017, it now carries legal protection alongside Matsusaka Beef and Kobe Beef as one of Japan's Three Great Wagyu. It is prized for snow-fine marbling, a moist and tender texture, and fat with a refined, gentle sweetness.
Taste & Texture
Omi Beef is defined by snow-fine marbling (fat intramuscular distribution), a moist and tender texture, and fat with a refined, gentle sweetness. Extended feeding (typically 28 months or more) using high-quality groundwater from the Lake Biwa basin, abundant rice straw, and the clear seasonal temperature swings between summer and winter produces the breed's distinctive beef quality. Marbling generally reaches BMS No. 5 or above, with fat dispersed in fine veins that creates a striking contrast against the lean meat.

Variety Comparison
vs. Matsusaka Beef
Omi Beef holds GI No. 56 (2017) and is legally protected, whereas the standard Matsusaka Beef brand has no GI registration (its elite 'Tokusan Matsusaka' subset is registered separately as GI No. 25) and otherwise relies on the council's own trademark and certification system. Both require Japanese Black cattle, but the geographic scope differs: Omi Beef specifies "raised longest within Shiga Prefecture," while Matsusaka Beef specifies "raised longest within Mie Prefecture's designated production zone (formerly 22 municipalities)." Omi Beef accepts both heifers and steers; Matsusaka is limited to virgin heifers. Historically, Omi Beef's lineage goes back 400 years — the oldest of any Wagyu brand — while Matsusaka developed from the Meiji era onward driven by Tokyo demand. Matsusaka (especially Tokusan Matsusaka Beef) tends to command the highest prices among the three great Wagyu.
vs. Kobe Beef
Both are GI-registered brands (Omi = No. 56/2017, Kobe = No. 3/2015), but Omi Beef's only requirement is "Japanese Black raised longest within Shiga Prefecture" with no lineage restriction, whereas Kobe Beef imposes a dual requirement of Tajima cattle bloodline plus rearing within Hyogo Prefecture. In terms of international recognition, Kobe Beef (KOBE BEEF) is overwhelmingly better known globally; Omi Beef's strength lies in its domestic historical brand story — 400 years of shogunate tribute. Price ranges are broadly comparable for both, with most product in the ¥30,000–¥150,000 range.
Breeding History
The roots of Omi Beef trace back to the early Edo period, when the Hikone Domain (Ii clan) encouraged the production and processing of cattle — mainly repurposed draft animals — within the domain. At a time when eating meat was publicly taboo in Japan, Hikone was uniquely permitted to process and present beef to the Tokugawa shogunate as "medicinal food" (yojo-niku) and in the form of preserved beef paste called henpongan (反本丸). This nearly 400-year lineage is the basis for Omi Beef's claim as the oldest Wagyu brand. With the lifting of the meat-eating ban in 1872 (Meiji era), distribution to the Kyoto-Osaka-Kobe region expanded rapidly, and the Omi Beef name took hold even in Tokyo. Cattle were also shipped to meet demand from foreign residents after the opening of Kobe Port; historical records suggest that much of the beef exported from Kobe under the name "Kobe Beef" at the time was in fact Omi Beef. After World War II, Shiga producers and distributors organized the Omi Beef Production and Distribution Promotion Council and formalized the certification standard of "Japanese Black cattle raised longest within Shiga Prefecture." A trademark was registered in 2007, and on December 15, 2017, Omi Beef was officially registered as GI No. 56 under MAFF's Geographical Indication system, giving the name full legal protection as a regional brand.

How to Choose
-
Genuine Omi Beef carries the official certification mark (stamped on the carcass) and a registration number issued by the Promotion Council; this information is also listed on certified retailers' packaging and furusato nozei (hometown tax) gift products.
-
For the best marbling, look for fat distributed evenly in fine, snow-like veins.
-
Fat should be white to pale cream with a slight sheen, and the lean meat should be a vivid red with visibly fine muscle grain.
-
Products bearing the GI-registered Omi Beef logo are legally protected authentic goods.
How to Store
-
Thick-cut steaks are best cooked within 2–3 days of purchase; thin-sliced cuts (for sukiyaki, etc.) within 1–2 days.
-
For longer storage, wrap tightly in plastic film, place in a freezer bag, and freeze — use within 3 weeks.
-
Thaw slowly in the refrigerator to minimize drip and preserve the fat's flavor.
-
Highly marbled cuts have a low fat melting point, so remove them from the refrigerator just before cooking to maximize the melt-in-the-mouth texture.
Frequently Asked Questions
Does Omi Beef really have a 400-year history?
Yes. From the early Edo period, the Hikone Domain (Ii clan) processed and presented beef to the Tokugawa shogunate as medicinal food (yojo-niku) and preserved paste (henpongan), making it the only domain to do so annually. At a time when eating meat was publicly taboo in Japan, Omi maintained a beef culture for nearly 400 years — making it the oldest lineage of any Wagyu brand.
When was Omi Beef registered as a GI?
Omi Beef was registered as GI No. 56 under MAFF's Geographical Indication system on December 15, 2017. While newer than Kobe Beef (GI No. 3/2015), the registration gives the Omi Beef name full legal protection as a certified regional brand.
What are the differences between Omi Beef, Matsusaka Beef, and Kobe Beef?
All three are Japan's Three Great Wagyu, based on Japanese Black cattle, but their geographic and bloodline requirements differ. Omi Beef requires "raised longest within Shiga Prefecture"; Matsusaka Beef requires "raised longest within Mie Prefecture's Matsusaka production zone"; Kobe Beef requires "Tajima cattle bloodline × raised within Hyogo Prefecture." GI registration: Omi (No. 56) and Kobe (No. 3) are registered; the standard Matsusaka brand is not, though the elite Tokusan Matsusaka subset was registered separately as No. 25. Historically, Omi is the oldest at 400 years, Matsusaka developed from the Meiji era, and Kobe spread internationally from the Meiji-era foreign settlement.
Are "Hikone Beef" and "Omi Beef" the same thing?
They overlap significantly but are not strictly identical. "Hikone Beef" (Hikone-ushi) is a historical term from the Hikone Domain era; today it is used partially as a sub-regional brand referring to Omi Beef cattle raised specifically in the Hikone area. In general commerce, "Omi Beef" is the unified term used across furusato nozei listings and butcher shops.
What should I look for when ordering Omi Beef through the furusato nozei (hometown tax) program?
Look for gifts from Shiga Prefecture municipalities (Ryuo Town, Omihachiman City, Higashiomi City, Koka City, Maibara City, etc.) that explicitly state "Omi Beef" and display the Omi Beef Production and Distribution Promotion Council certification mark or registration number. Most products fall in the ¥30,000–¥150,000 range and can be selected by cut — roast/sirloin steak, sukiyaki thin slices, shabu-shabu, and more.
