Best for baked sweet potatoes, Anno sweet potato fair

Known as a specialty of Tanegashima, Anno sweet potato is a type of Japanese sweet potato and a typical agricultural product of Tanegashima. Anno sweet potatoes are known as a high quality variety and have a unique flavor and sweetness.

Anyone can participate in this fair, but there are several criteria that can be used as a reference for judging the quality of Anno sweet potatoes or sweet potatoes. Some examples are listed below.


In terms of appearance, good quality Anno or sweet potatoes should be well-shaped, have few blemishes or discolorations, and have a beautiful, bright color. It is also important that they are of uniform size.


Good quality is considered to be yellowish-orange in color for Anno sweet potatoes and reddish brown for sweet potatoes. The color is considered good if it is bright and uniform. The evaluation is based on intuition.


Anno sweet potatoes or sweet potatoes have a distinctive sweet aroma. The rich aroma is a key point to indicate high quality.

At the fair, the Anno sweet potatoes still had soil attached to them, so they only had an "earthy" smell.


Anno sweet potatoes or sweet potatoes are characterized by their rich sweetness and sticky texture. They are considered to be of good quality if they have a strong flavor and are chewy.

Also, it is said that Anno sweet potatoes need to be exposed to cold weather after harvesting to produce sweetness, so they all devise ways to produce sweetness.

However, since fresh Anno sweet potatoes are displayed at the fair, the taste cannot be judged.

Water content

Appropriate moisture content is also a key to quality, but this level of quality cannot be determined at a fair. It is a game of "feel".

If the moisture content is too little, it will be dry, and if the moisture content is too much, the taste and quality will deteriorate. The storage conditions of Anno sweet potatoes greatly affect the moisture content, so they need a proper storage place after harvesting.

These criteria can be used as a reference for the Anno sweetpotato fair. However, at the fair, the judging is based on personal preferences.

History of Anno sweet potato

The history of Anno sweet potato dates back to the early Edo period when Araki Mataemon, a Chinese herbalist who immigrated from Ming Dynasty, brought a seed of sweet potato called "Beniharuka" that had been cultivated in China.

Later, the variety was improved to suit the mineral-rich climate of Tanegashima's seaside area, and today it is one of Tanegashima's representative specialty products.

Anno sweet potato varieties

There are many varieties of Anno sweet potatoes. The two main varieties on the island are "Beni" and "Kogane", but there are also "Beni Haruka", "Beni Azuma", "Benimaru", "Shiro Azuma", and "Kintoki".

I prefer the smaller ones to the larger ones, but when I send Annou imo to a stranger, I send the "larger ones". If they are too small, people in Honshu (the main island of Japan) may think that small Annou imo are "scraps". I don't want to send too small potatoes because people in Honshu may mistake them as "scraps".

Did you know? Virus-Free Seedling Initiative for Anno Sweet Potatoes at Tanegashima High School

On Tanegashima Island, crop production is sometimes reduced due to virus infections and other pests. For this reason, the Agriculture Department of Tanegashima High School is working to propagate virus-free seedlings. Virus-free seedlings are seedlings from which pathogens have been completely removed to prevent outbreaks of pests caused by virus infections and other diseases. Tanegashima High School has succeeded in propagating virus-free seedlings, which has contributed to increasing the production of Anno sweet potatoes.

Tissue culture technology is used to propagate virus-free seedlings. Tissue culture is a technique for creating new plants by taking roots, stems, leaves, etc. from plant tissue and regenerating them on a culture medium. Propagation by tissue culture plays a very important role in completely eliminating pathogens such as viral infections.
