Tsushima Nihon Mitsubachi Honey

The honey itself

The Nihon mitsubachi harvests once. In autumn, when the full seasonal sequence of the forest is complete, the beekeeper opens the hive. In the traditional log hive method, the top is broken and the comb removed. The honey is then filtered by hand over several days, passing slowly through cloth or mesh without heat or centrifuge. The round comb structure of the native bee's hive does not accommodate the frame extraction used with European bees. The old method is the only method.

What results is a dark honey -- amber to deep amber, darkening with age -- with an aroma that carries the complexity of a forest year. The flavor is described consistently as mellow, rich, and mature: not the clean sweetness of a single-source honey, but something with more layers, more depth, what one Tsushima beekeeper described as the honey having time to slowly mature and enhance itself through the season. The botanical record is complete: everything that flowered within the bee's range, from spring through the autumn harvest, is present in the jar.

The Tsushima honey -- from this island, this forest, this tradition -- is described as gentle and mellow, with a depth that builds slowly. Ripe persimmon and loquat are the flavors L'Abeille reaches for. That character shifts wherever the bee meets a different forest. Kagoshima virgin forest honey runs deeper, with an acidity some liken to vintage wine. Nagano and Aichi carry their own mountain signatures. Same bee, different forest, different honey -- and the difference is worth knowing before you buy.

The island that kept the old way

Tsushima is not easy to reach. An island 82 kilometers long and almost entirely mountainous, it sits in the Korea Strait between Kyushu and the Korean Peninsula, closer to Busan than to Fukuoka. Ninety percent of its land is forest. There is almost no agriculture to speak of, which means almost no pesticides. There are no bears. There are Japanese giant hornets, but no European honeybees -- there has never been a reason to introduce them, and so they were never introduced.

What Tsushima has, and has had since at least the seventh century, is the Nihon mitsubachi and the tradition of keeping it in log hives called hachido. The logs are cut from cryptomeria or cypress to a height of 70 centimeters, bored to 22 centimeters in diameter. The entry holes are cut to the width of a cigarette -- large enough for the native bee, too narrow for a hornet scout. Beekeeping equipment on Tsushima has been found functioning as a religious symbol in at least one village, evidence that the relationship between the islanders and their bees has dimensions beyond the practical. A survey found 379 households on the island still producing honey from Nihon mitsubachi. They eat it daily. They use it traditionally as a sauce for freshly pounded mochi rice cakes. The honey is not a specialty product to them. It is a staple.

What these islanders have maintained, almost by accident of geography, is the oldest form of Japanese beekeeping still in living practice.

A bee designed for the Japanese forest

The Nihon mitsubachi diverged from its Korean ancestors approximately 20,000 years ago, when rising sea levels separated Tsushima from the peninsula and the two populations could no longer interbreed. What emerged over the millennia that followed is a bee shaped specifically by the conditions of the Japanese archipelago -- its forests, its seasons, its predators.

The bee prefers trees with plain, inconspicuous flowers: Phellodendron amurense, Meliosma myriantha, and others that bloom in sequences through the mountain forest. It follows these sequences through the full growing season, visiting not one source but the entire succession, building honey from the cumulative record of the year. This foraging behavior is what makes monofloral honey impossible for this bee. It is also what produces honey of a depth and complexity that European single-source honeys cannot replicate by definition.

The bee is also resistant to Varroa jacobsoni, the mite that devastates European honeybee colonies worldwide. This resistance is likely a product of the same long coevolution that shaped its other characteristics. The Nihon mitsubachi has been living with the organisms of the Japanese forest for a very long time. It has developed accommodations.

Its most striking accommodation is the defense against other predators such as Japanese yellow hornets (Vespa simillima xanthoptera) and the mighty Asian giant hornet -- Vespa mandarinia, large enough to decapitate hundreds of European bees per minute. Hiroshi Aiba, a beekeeper on Tsushima, puts it plainly: Japanese honeybees move nimbly and collect from a hundred different flowers. The hornet defense is part of the same agility. When a scout hornet enters a Nihon mitsubachi colony to mark it for attack, the colony responds immediately. Hundreds of bees surround the hornet in a living ball, covering it completely, and vibrate their flight muscles in unison -- the same mechanism they use to warm the hive in winter. The temperature inside the ball rises to 46 degrees Celsius. The carbon dioxide concentration rises simultaneously. The hornet cannot survive 46 degrees combined with that level of CO2. The bees can tolerate up to 50 degrees. The margin between the bee's tolerance and the hornet's fatal threshold is four degrees Celsius. It is enough. The scout dies before it can mark the colony for attack.

European colonies have no answer to the giant hornet. The Nihon mitsubachi has been living alongside it long enough to cook it alive.

From the Nihon Shoki to the Ark of Taste

The first written record of honeybees in Japan appears in the Nihon Shoki -- the Chronicles of Japan, completed in 720 AD. It records that Ambassador Yoho from the Korean kingdom of Baekje released four hives of honeybees on Mount Miwa. Historians now believe this introduction was artificial rather than natural migration -- that Korean bees were deliberately brought to Japan, most likely during the upheaval of the Imjin War in the late sixteenth century, along with Korean beekeeping knowledge. Whatever the origin, the bee and the islands adapted to each other over centuries.

By the Heian period, honey from Japanese bees was being sent to the Imperial Court as tribute from the provinces. During the Edo period, beekeeping with the native bee became systematic enough that Ekiken Kaibara's 1709 botanical encyclopedia Yamato Honzo could classify honey by where it was harvested -- rock honey from mountain crevices, tree honey, ground honey, house honey -- while noting that the bee producing all of them was the same creature.

Then in 1877, the Western honeybee arrived in Japan, along with the Langstroth hive and European frame beekeeping methods. The European bee produced four to five times more honey per colony. Commercial beekeepers converted. The Nihon mitsubachi was increasingly seen as inefficient, its honey as a rustic relic. Production declined. Knowledge of the old methods contracted to isolated pockets -- island communities like Tsushima, mountain villages where the old ways persisted for their own reasons.

Since the 1960s, development and neonicotinoid pesticide use have further reduced the habitat available to the native bee. Nationwide, approximately 5,000 beekeepers keep Nihon mitsubachi, but only 50 to 100 operate at a commercial scale. Annual production is estimated at around 30 metric tons -- compared to 2,800 metric tons produced by European bees in Japan. The Slow Food Foundation has listed Nihon mitsubachi honey on its Ark of Taste, a catalog of foods at risk of disappearing.

Tsushima remains the exception. The island's geography -- its isolation, its forests, its absence of intensive agriculture -- has preserved both the bee and the tradition that keeps it. Here the practice is not a revival or a heritage project. It is simply what people have always done.

What it costs and where to find it

Nihon mitsubachi honey is not a honey you encounter by accident. It requires seeking out, and in most cases it requires understanding what you are looking for before the price makes sense.

L'Abeille, Japan's department store honey specialist, carries vintage-dated lots at prices that reflect what the honey actually is: the 2017 Tsushima and Nagasaki vintage is listed at 54,000 yen for 350 grams. The 2025 sakura premium lot is 64,800 yen. These are not premium markups on a commodity product. They are prices for a honey produced in quantities so small, from colonies so limited in yield, by beekeepers maintaining a tradition with no industrial equivalent, that the fine wine comparison is not a stretch. It reflects the same scarcity economics.

Dorato in Kyoto carries Nihon mitsubachi from Nagano and Aichi prefectures, at price points that reflect smaller-scale specialty retail rather than department store positioning. The Tsushima lots at L'Abeille are shipped refrigerated, sold in 36-gram jars, and sell out. There is no guarantee of availability from year to year, because production itself varies with the season, the forest, and the survival of the colonies through winter.

Outside Japan, Tsushima Nihon mitsubachi honey rarely appears. When it does, the label will say Tsushima or Nagasaki -- the administrative prefecture. A label that says only Nihon mitsubachi or hyakkamitsu without a named location is a different honey from a different forest. L'Abeille ships internationally. That is the most reliable route to the specific honey this page describes.

How to use it

On Tsushima the traditional answer is direct: eat it as it is, or spread it over freshly pounded mochi rice cakes. This is not a prescription for elaborate use. It reflects what the honey actually rewards -- attention to the thing itself rather than its role as an ingredient. A honey this complex, this scarce, and this expensive is best tasted on its own first, without competition from other flavors.

Where pairing is appropriate, the honey's density and forest depth suit foods with equivalent weight. Aged cheeses -- particularly hard, nutty styles -- can hold their own against it without disappearing. Kuzugiri, the traditional kuzu starch noodles mentioned in Slow Food documentation, is the classic Japanese pairing: clean, cool, lightly textured, allowing the honey's complexity to read clearly.

Traditional Japanese medicine framed this honey as having enhanced medicinal properties from its single annual maturation -- a belief documented across Heian court records and Edo-period botanical encyclopedias, and still the framing used by specialist retailers today. Whether or not you accept the traditional claim, the production facts support it partially: the honey matures undisturbed through a full season, hand-filtered without heat, with enzymes and pollen content intact. It has not been processed in any way the old method would not recognize.
