Have you noticed clusters of small round brown fruit in a Vietnamese market or supermarket? They are longan. Their modest appearance can make them easy to overlook if you do not know how to eat them.
Peeling is simple: press the shell with your fingers, crack it and open the split to reveal the pale edible aril. A thumbnail can help start a firm shell; a knife is usually unnecessary.
This article follows the process of finding, pricing, choosing, peeling, eating and storing longan in Vietnam, then explains the rules for taking it to Japan.

The Vietnamese Name: Nhãn
Longan is called Nhãn in Vietnamese. Remembering this word is useful when shopping.
The dark seed and pale aril resemble a dragon’s eye, the name explained in Longan Guide. Nhãn also corresponds to “eye” in Sino-Vietnamese vocabulary.
You can ask the price with this phrase:
Một ký nhãn bao nhiêu?
“How much is one kilo of longan?”
In northern Vietnam, một cân is also used for one kilogram.
Longan is often sold by weight, with prices quoted per kilogram. Clusters may still have their small branches attached.
Longan’s Taste, Texture and Differences from Lychee
Vietnamese longan has rich sweetness reminiscent of honey. In the author’s tasting notes, the aril felt soft and springy with concentrated, honey-like sweetness. Compared with lychee, its fragrance was gentler.
The fruit is bite-sized, but the juice can make hands sticky. A tissue or paper towel is useful.
Prices and Where to Buy Longan in Vietnam
In July 2026, the author found a supermarket list price of 79,900 VND/kg. A discounted pack weighing 0.86 kg cost 38,700 VND, equivalent to about 45,000 VND/kg. These are dated purchase examples rather than a current universal market price; variety, origin, season and shop affect prices.
Open-Air Markets and Street Fruit Sellers
Markets often display heaps of longan in large baskets and sell it by weight. Clusters can include small branches.
Supermarkets
Packs make the weight and total cost easy to check. Look for discounts as well as the original price on the label; reductions can be substantial.
Fruit Shops and Delivery Apps
Fruit specialists and delivery services may offer clearer origin and freshness information, although prices can be higher than at markets.
How to Choose Good Longan
As explained in Longan Guide, longan does not become sweeter through ripening after harvest. Choosing good fruit at the time of purchase matters.
Check the whole cluster. Look for smooth shells ranging from yellowish brown to light brown, depending on the variety. Color alone is not enough: check for splits, mold, insect damage, leaks and unusual smells. Larger fruit without obvious damage are a useful guide.
How to Peel Longan: Three Steps by Hand
The shell is thin and fairly firm, but usually does not need a knife cut.
- Hold the fruit between your fingers. Press a thumbnail lightly against the shell and crack it.
- Open both sides from the split to expose and remove the translucent white aril.
- Remove the dark, hard seed from the center before eating the aril.
You can crack the shell with your fingers and eat the aril after removing the seed.
Four Ways to Enjoy Longan in Vietnam
1. Eat It Fresh
Fresh is the simplest way to eat longan in Vietnam. Crack the shell and remove the seed. Chilled fruit makes a pleasant dessert on a hot day.
2. Chè hạt sen nhãn lồng: Lotus Seed and Longan Sweet Soup
Chè hạt sen nhãn lồng is a traditional Vietnamese sweet soup combining lotus seeds, hạt sen, and longan. Some accounts associate it with court cuisine. It can be served warm or chilled.
3. Dried Longan: Long nhãn or Nhãn nhục
Dried longan is called long nhãn or nhãn nhục. Some products retain the shell, while others consist of dried, pitted arils. It may be eaten as sold or rehydrated for sweet soups and drinks. Chinese names include guiyuan rou and longyan rou.
4. Dried Longan Tea with Rock Sugar
Dried longan can also be simmered with rock sugar for a sweet drink, known by names such as trà nhãn nhục đường phèn. Enjoy it warm or over ice.
Can You Eat Longan Seeds?
The seed and shell are not the edible portions. The seed is hard and can be a choking hazard, particularly for small children; remove it from the aril before eating.
For children, remove seeds completely before serving and supervise eating. Seek urgent medical assistance if a child chokes.
Storing Longan: Refrigeration and Freezing
Longan will not become sweeter by leaving it after purchase, so eat it while in good condition. Chill promptly and use a bag to reduce drying. A practical home target is five to seven days, but storage history affects quality: inspect the fruit and smell it before eating. Shell darkening alone may reflect drying; reject moldy, leaking or foul-smelling fruit.
- After purchase: avoid direct sunlight and heat; chill promptly.
- Aim to eat within five to seven days: refrigerate in a bag to reduce moisture loss; check the condition before eating.
- For longer storage: seal and freeze whole fruit or peeled, pitted arils.
Can You Take Fresh Longan to Japan?
Travelers cannot bring fresh longan bought in Vietnam into Japan as a personal souvenir.
The Plant Protection Station’s Vietnam guidance lists fresh longan among fruit that cannot be carried in travelers’ personal baggage. Check the current guidance before travel.
As discussed in Longan Guide, conditional commercial imports opened on November 18, 2022, for Vietnamese fresh longan meeting specified standards and detailed procedures. That is separate from bringing market-bought fruit home in baggage. The Plant Protection Station lists dried longan as outside plant quarantine requirements. Highly processed items such as canned fruit are also generally outside those requirements; check the product and route before buying.
Quarantine conditions can change. Always check the latest official information before traveling.
