Nagasaki Long Eggplant

Nagasaki Long Eggplant

(Solanum Melongena) Nagasaki Long Eggplant is a popular Japanese heirloom vegetable. It has been grown in Nagasaki, Japan for over 100 years.

There are short varieties of this species, but these can also be found in the West occasionally. The long variety was first grown by a farmer named Kato who lived on one of the islands that forms Nagasaki Prefecture.

The mild, delicately flavored flesh is less bitter than some of the varieties you would typically find in the grocery store.

These are sometimes referred to as “Japanese eggplant” or “Asian eggplant.”

The shape of this Japanese eggplant resembles a samurai sword, the tip tapering to a point and the blade narrowing at the hilt.

These vegetables are purple on the outside with white flesh. They have a thin skin that is tender when sautéed.

This eggplant is longer and more slender than other types, but has a high yield.

How to grow Nagasaki Long Eggplant?

  • Start seeds 10 weeks before transplanting outside. They can be transplanted into the ground when soil temperatures are 55-60F.
  • This Asian eggplant is a warm weather variety, so sowing seeds outside in late spring to early summer will produce the best harvest. They can be grown year round in warm climates and when protected from frost.
  • Set the plants in fertile, moist soil that is free of weeds. Nagasaki long eggplant needs a long warm growing season to produce its trademark fruits. Eggplant is very susceptible to frost, so if you are growing the plant outdoors, make sure your area has a long growing season.
  • The long variety is around 4 feet (120cm) tall and grows to about 20-24 inches wide but this depends on growing conditions.
  • As the plants grow, thin them out and remove any yellow leaves to allow proper air flow. The eggplants will turn purple with a slight shine when they are ripe and ready to pick.
  • Eggplants do well when fed with compost or a balanced fertilizer for fruit or tomatoes. Apply at least monthly, but more often if grown in containers or receiving heavy rain fall.
  • Nagasaki Long Eggplant tolerate extreme heat extremely well, but are frost sensitive. This makes them a good choice if you live where summers are hot and winters are mild.

Harvesting Nagasaki Long Eggplant

For the best flavor, harvest eggplants when they are 3-4 inches long and have a shiny, purple skin. This will prevent them from becoming bitter or tough.  

After harvesting Nagasaki Long Eggplant, they can be stored for a few days in a plastic bag in the refrigerator.

Store at a cool room temperature for 1-2 days and the crisper drawer of your refrigerator if longer.

The Nagasaki Long Eggplant is an Asian vegetable that needs little maintenance and it fits well in small garden.
