Growing regions & local information

A former pig farmer in Lao Cai province grows 3 hectares of everbearing lime year-round, harvesting 20 tonnes and just under about 200 million dong a year. We read what a year-round-fruiting acidic citrus shows for Japanese beverage and food sourcing in the seasons when domestic sudachi and kabosu rest.

On 2 ha of poor land in Pa Long, Lao Cai province in northern Vietnam, sweet corn grown for a company by eight ethnic-minority households yielded 15 tonnes/ha in 90 days. Contract production, in which seed, fertilizer, and technology are handed over up front and the entire crop is bought at 6,000 dong per kilogram, levels out cash income in the mountains. We read whether it could become a third candidate growing area for Japan's frozen-corn sourcing.

The fisheries center in Tuyen Quang province has produced more than 50,000 artificially bred fry of the premium river fish ca chien since the start of the year. By producing in-house, within the growing area, the juveniles that once depended on wild catch, the raw material for cage farming is moving toward stability. We explain the yardstick by which Japanese sourcing assesses a growing area.

In the Luong Tam area of Can Tho City, 180 households and 250 hectares are taking up tom-lua (shrimp-rice farming) using paddy fields. We interpret this low-input model that turns salt-damaged land into a resource, and its meaning for Japanese premium sourcing.

Near Noi Bai outside Hanoi, a farmer who replaced poor, barren paddy fields with greenhouses to grow a white-type grape of Korean origin called "milk grape" is achieving good results. According to a report carried by the local agricultural journal Nong nghiep Moi truong on July 25, 2026, Ta Quoc, born in 1986...

ソンラやダクラクへの一極集中を避けたい日本のコーヒー・ナッツバイヤーへ。北西部ディエンビエン省がアラビカとマカダミアを軸に描く輸出産地構想を、面積・計画・調達視点で読み解く。

In Ha Tinh province, Vietnam, mung beans had both a bumper crop and high prices. Dried beans go for around 300-some yen per kilo, and middlemen come to the fields to buy, selling out immediately. For Japan's sourcing of bean-sprout and bean-paste raw materials—almost entirely reliant on imports—it becomes a yardstick for rethinking dependence on China.

In Dai An hamlet, Phu Ninh, Da Nang City, 6.2 hectares of low-profit paddy are being converted to lotus cultivation, apple-snail farming, and community tourism. We read, from a Japanese buyer's perspective, a profit of about 4 million VND per sao—2–3 times that of rice—and a candidate lotus-raw-material source that can be visited and verified.

Haiphong's organic rice x ragworm combined farming brings 500–600 million dong per hectare a year. Ragworms, which do not grow in paddies where pesticides remain, serve as an indicator of the water environment. We read its meaning for Japanese sourcing.

Rice farming in the Mekong Delta has long been said to be "done by experience." The timing of sowing, how water is let in, how much fertilizer is spread—all of it rests on intuition passed from parent to child. Yet in a strongly acidic corner of An Giang province, a farmer who replaced that intuition with soil design, without letting the rice wither...
