Aomori is the most vegetable production area in Tohoku region. Chinese yams and garlics are famous as the Aomori-brand vegetables. Japanese radishes, carrots and tomatoes are also widely produced in Aomori. In addition, there are some traditional vegetable crops such as ‘Hirosaki-zairai’ red pepper and ‘Nukazuka’ cucumber, and also many edible wild plants. Recently, vegetable production in cold winter has been popular for the purpose of improving profitability of Aomori farmers. We have so many research subject and/or problems to be solved. Why don’t you join us and do research contributing to revitalization of Aomori region


Research Theme

Specialty: Horticulture, Vegetable science


1. Research for cultivation technique, breeding, branding of regional special products

 1) Breeding program and research of ‘Hirosaki-zairai’ red pepper

 2) Branding of ‘Hirosaki-zairai’ red pepper as a special local vegetable

2. Research of onions as a ‘substitute crop’ for rice field

 1) Research of the cultivation methods for onion production

 2) Research of the phytochemicals in onions such as flavonoids and fructo-oligo saccharides

3. Research of asparagus as a health promoting vegetable

 1) Winter production of asparagus

 2) Phytochemicals in asparagus such as flavonoids and saponins

4. Carrots

 1) Effects of storage under snow lay in winter on the quality of carrots, such as contents and flavor

 2) Characteristics of new cultivars

5. Other

 We have some other research subjects, and we would accept joint researches in any kind related to the vegetables produced in cool region. Please contact us anytime.
