Kyung Nam Nursery was established in 1994 as a joint stock company. It specializes in seedling production. It has been exporting onion seedlings to onion farms and horticultural centers in Japan for 20 years. Director Kim Do-hun is the successor of his farming business. He studied Japanese in Fukuoka Prefecture in 2002. He joined the company in 2005. The following year, 2006, he was admitted to the Master of Horticulture Science program at Kyungpook National University and graduated in 2008. For the past 20 years, he has been in charge of exporting onion seedlings to Japan at Kyung Nam Nursery.

On August 23, 2022, onion seedlings from Kyung Nam Nursery, also known as Changnyeong Mini Onion, were shipped to Japan. Approximately 2.4 million seedlings were exported. They were sown on about 9,900 m2 of land in late February and harvested in early June. It takes about 100 days for them to reach full growth. In Japan it is called Set-Q and in Korea it is called mini onion. The standard size ranges from 2.5 g to 7 g. The seedlings that have outgrown the size required for export are sold as standard onions in Korean markets, about 3 tons per year. They are sold in Korean markets from July to September. In the first 10 years of export, the amount of export increased steadily and peaked at 4.5 million onions. Now the amount has almost halved. This is due to the declines in demand from Japanese farmers due to the aging of the population and the decline in population in farming villages. The price started at JPY 2.5 per piece, but now a flat rate of JPY 4 applies. From 2013 to 2022, the export volume will be about 33 million pieces, and the export revenue was about JPY 1.21 billion.

Director Kim Do-hun said, "I don't remember exactly how we started the export business because I was a student at the time. In 1999, my father, who was the president of Kyung Nam Nursery, exported eggplant, watermelon and cucumber seedlings to Yamato Farm in Nara Prefecture, Japan. This gave us the opportunity to export mini onions, the onion seedlings, to Japan. Kyung Nam Nursery sows onion seedlings in February and harvests them in June. We sell some of the harvested products to Nonghyup supermarkets in Korea and export most of them to Japan. For the past 20 years, we have exported about 3 million onions per year at an average price of JPY 3.5 each, and have exported about 60 million so far," he said. He explained the start of their onion seedling export business and its current status. In June, they harvest rice seedlings and onion seedlings. In July and August, they harvest autumn cabbage for kimchi season, and in September and October, tomatoes and onions. 

Most of the onions in Korea are of the single variety, which is sown in autumn and harvested in the following spring and summer. The main producer of onions in Korea is the southern region, including South Jeolla Province, South Gyeongsang Province, and North Gyeongsang Province. In 2020, South Jeolla Province accounted for the largest area (39.4%), followed by South Gyeongsang Province (19.5%) and North Gyeongsang Province (18.6%). These three provinces are the main producers of onions, accounting for 77.4% of the area. The production volume of onions in Korea was 274,000 tons on 7,700 hectares in 1980, and 878,000 tons on 16,700 hectares in 2000, which indicates a two-fold increase in area and a four-fold increase in production volume. In 2020, Korea's onion cultivation area was 14,700 hectares, and the production volume was 1,168,000 tons.
