Durian, called the "king of fruits," is known for its rich, creamy flesh and intense aroma. Vietnam has now achieved rapid growth in exporting this durian, and durian has become the most important item leading the country's fruit exports. Much of the frozen durian seen in Japanese supermarkets and online shops is also from Vietnam.
This article digs into Vietnamese durian from the perspective of its growing regions and exports. We cover the main producing area, the Central Highlands, varieties such as Ri6 and Monthong, the season, the structure of rapidly expanding exports to China, and how to obtain it in Japan. If you want to learn about it alongside other fruit, see Complete Guide to Vietnamese Fruit as well.
The Basics of Vietnamese Durian
Durian is a fruit of the mallow family, with yellow, sticky flesh inside a large, spine-covered fruit. While it is called the "king of fruits" for its rich sweetness and cream-like texture, it is also known for its distinctive strong aroma. For its rich flavor, it has long been prized in Southeast Asia.
Opinions on this aroma are divided, and it is not unusual for it to be banned from hotels, public transport, and airplanes. Its spiky appearance sometimes leads to confusion with jackfruit, but they are different fruits. Once you are hooked on its aroma and texture, it is an unforgettable, addictive fruit. In Vietnamese it is called "sau rieng," and in early summer it is piled high at markets and roadsides.
The Main Producing Area Is Dak Lak Province in the Central Highlands
Vietnam's durian-growing regions have expanded greatly along with export growth. At the center is the Central Highlands, also known for coffee. In response to the expanding export market, the cultivated area has grown rapidly, and durian is becoming a major crop of the Central Highlands alongside coffee.
Dak Lak and Lam Dong provinces
Dak Lak Province in the Central Highlands is one of Vietnam's largest durian-growing regions. Its high-altitude climate with large day-night temperature swings deepens the flavor of the flesh. Cultivation is also active in neighboring Lam Dong Province, and a growing number of farmers have converted coffee fields into durian orchards. Buon Ma Thuot, the main city of Dak Lak Province, is a coffee distribution hub and at the same time a durian trading base. The agriculture of the Central Highlands is central highlands category explore in depth.
The Mekong Delta Growing Region
In the southern Mekong Delta, durian is also grown in provinces such as Tien Giang. Because harvesting begins earlier than in the Central Highlands, a relay among growing regions widens the shipping period. The differences in harvest timing by region support a near-year-round supply. Mekong Delta fruit can start appearing as early as early spring, then passes the baton to Central Highlands fruit heading into summer.
Varieties: Ri6 and Monthong
Vietnamese durian circulates in two broad varieties. They differ in both flavor and export positioning, and since they are hard to tell apart by appearance, checking the variety by growing region or label is surest.
| Variety | Characteristics | Positioning |
|---|---|---|
| Ri6 (Ri sau) | Rich, creamy flesh with small seeds | A popular Vietnamese variety. Traded at high prices |
| Monthong (Dona variety) | Mild sweetness, restrained aroma, plenty of flesh | Of Thai origin. The mainstay of exports |
Ri6 has rich flesh and small seeds, making it satisfying to eat, and it is a highly popular variety both domestically and for export. Monthong has a relatively gentle aroma and good shelf life, and because it suits long-distance transport it has become the mainstay of exports. In the growing regions, which variety to plant to match export-market demand is an important decision. Demand for Monthong is large in the Chinese market, and the growing regions are advancing variety selection with exports in mind, while domestic connoisseurs firmly favor Ri6's richness.
Season: May to August, and Year-Round Production
Vietnamese durian's harvest period shifts by region. Overall, the peak is from early summer into summer.
The Mekong Delta enters the harvest period early and the Central Highlands later, so across all growing regions the season centers on around May to August. Through techniques such as grafting, water management, and off-season cultivation using covers, year-round production that shifts the shipping period is also advancing. Widening the shipping period leads to price stability and a continuous export supply. At the peak of the season, prices tend to fall and the flavor comes through, so if you want to taste it locally, June to July is the target. For the best times for other fruit, see Vietnam Fruit Seasonal Calendar for reference as well.
The Intense Aroma and How to Eat It
Durian's appeal is, above all, its rich flavor. Even people who brace themselves at the strength of the aroma may find their impression changes once they taste the flesh. It is a fruit that clearly divides likes and dislikes, but when the season comes, fans head to the growing regions seeking this flavor. Monthong, with its relatively gentle aroma, is known as a variety easy to eat even for those not used to durian.
The basic way to eat it is to split the spiny shell, take out the yellow flesh, and enjoy it as is. The cream-like texture and rich sweetness bring to mind a sticky custard. In Vietnam it is also enjoyed in desserts combined with glutinous rice, and as an ingredient for ice cream and sweets. When choosing one, a good sign of ripeness is that the aroma stands out and, when lightly shaken, there is a hint of the flesh moving inside. One whose shell spines are dense and which feels heavy has flesh packed inside, and one whose aroma rises strongly from a crack is a sign of ripeness. Freezing the flesh changes its texture from sticky to crisp, and some people enjoy it like ice cream.
Rapidly Expanding Exports to China and Changes in the Growing Regions
The sudden rise in the presence of Vietnamese durian has the rapid expansion of exports behind it. In particular, the opening of the Chinese market greatly changed the growing regions.
When China formally permitted imports of fresh durian in 2022, exports from Vietnam surged and the cultivated area expanded at once. In 2024, exports of frozen durian to China were also permitted, giving momentum to exports of processed products. Durian has now grown into the largest item in Vietnam's fruit export value. In some years, following the opening, export value jumped to more than ten times the previous year, lifting fruit exports as a whole. Developments around exports are Exports to Japan category as well.
On the other hand, a structure that relies on China for much of its exports also carries risk. If China tightens quarantine standards or curbs imports, fruit that has lost its destination could cause prices to crash. In the growing regions, thorough quality management and the diversification of export destinations, such as Japan, are challenges. To keep the trust of export destinations, thorough region-wide management of residual pesticides and production records is essential.
How to Buy Vietnamese Dragon Fruit in Japan
How you get Vietnamese durian in Japan varies by form. The mainstream is frozen.
Vietnamese durian makes up the largest share of Japan's durian imports, and most of it is frozen. Frozen durian appears in online shops and Asian grocery stores in the form of flesh packs or whole frozen fruit, and once thawed you can enjoy its creamy texture. Vietnamese fruit accounts for more than 60% of Japan's durian imports, and frozen is the majority among them. Fresh durian has limited distribution but is sometimes carried by specialty shops.

For how to proceed when sourcing for commercial use, see the practical import guide, we explain.
Case Studies: Growing Regions Changed by Exports
The durian export boom has greatly changed the landscape of the growing regions. Here we take up some concrete developments.
The 2022 China Opening and the Cultivation Boom
When China permitted imports of fresh durian in 2022, prices rose and farmers rushed to plant durian. In the Central Highlands, the move to turn coffee fields into durian orchards also spread. While the rapid expansion of cultivation over a short period boosted incomes, it also created new challenges of oversupply and quality variation. Because planted trees take several years to bear fruit, some voices worry about the boom overheating. The surge in demand for seedlings also caused a problem of low-quality and counterfeit seedlings circulating, and choosing legitimate seedlings has become a new challenge in the growing regions.
The New Market Opened by Freezing
When exports of frozen durian to China were permitted in 2024, exports of whole frozen fruit and flesh packs grew at once. Frozen keeps longer than fresh fruit and has fewer transport constraints, bringing a new outlet to the growing regions. The two-track approach of fresh and frozen is pushing exports up further. The export volume of frozen durian grew several-fold in a short period, and the strength of processing opened up a new market.
From China Dependence to Diversification
The rapid growth of exports has been supported by the Chinese market, but reliance on a single country is also a risk. If quarantine standards tighten or import restrictions arise, prices could swing sharply. In the growing regions, efforts to lower dependence are advancing, through developing markets such as Japan and strengthening the management of quality and production records.
