Shiitake mushrooms are native to East Asia and are widely cultivated and consumed around the world. They are a key ingredient in many Japanese dishes, including sukiyaki, udon, nimono, takikomi-gohan, and tempura. The Japanese name shiitake is derived from the Japanese kanji for tsuburajii (a type of tree native to Japan) and take (mushroom). The earliest written record of shiitake cultivation is found in a 13th-century Chinese text, which was later adapted by a Japanese horticulturist in 1796, creating the first guide to cultivating shiitake mushrooms in Japan.

Shiitake mushrooms are native to East Asia and grow naturally in Japan's forests
Shiitake mushrooms are native to East Asia and grow naturally in the forests of Japan. They are the most common edible mushroom in Japan and are used as a garnish in various Japanese dishes, including sukiyaki, udon, and tempura. They are also used as a source of dashi stock, a type of vegetarian broth. The Japanese take their shiitake seriously, as it is one of their main umami building blocks. Shiitake mushrooms are graded on many factors, including thickness, appearance, flavour, and size. They are widely cultivated and consumed around the globe, contributing about 25% of the total yearly mushroom production.
The scientific name for shiitake mushrooms is Lentinula edodes, and they are a type of macrofungus. They grow in groups on the decaying wood of deciduous trees, particularly the shii tree, a type of chestnut tree native to Japan. The word “shiitake” is derived from the Japanese word "shii," meaning the tree the mushrooms are typically found on, and "take," meaning mushroom. The mushrooms were first scientifically described in 1877 by Miles Joseph Berkeley, who named them Agaricus edodes.
Shiitake mushrooms have been cultivated in Japan for centuries, and the traditional method of cultivation has remained largely unchanged. The mushrooms are grown on logs of decaying wood, typically from trees such as chestnut, maple, and sawtooth oak. The logs are cut and placed near trees already growing shiitake or containing shiitake spores. This method of cultivation eventually moved from the forests to farms, marking the beginning of large-scale production.
In recent years, a new method of cultivation, known as the “sawdust method,” has been introduced. This method involves mixing nutrients with sawdust and adding shiitake mycelium to the mixture, which is then placed in bags or containers. This method is more convenient and easier to control the growing conditions, resulting in shorter mushroom growing cycles. Despite the introduction of new cultivation methods, the traditional log cultivation method is still used by many Japanese shiitake farmers.

They are the most popular edible mushroom in Japan
Shiitake mushrooms are native to East Asia and are widely cultivated and consumed around the world. They are the most popular edible mushroom in Japan, where they are used in many dishes. The Japanese take their shiitake seriously, as it is one of their main umami building blocks. The mushrooms are graded on factors such as thickness, appearance, flavour, and size. They are versatile and can be used in any cooking method, but baking, stir-frying, sautéing, grilling, and deep-frying are considered the major ways to enjoy their flavour.
Shiitake mushrooms are commonly used in Japanese cuisine as a garnish or as a source of dashi stock. They can be found in dishes such as sukiyaki, udon, nimono (a simmered dish seasoned with soy sauce, sugar, and dashi), takikomi-gohan (Japanese mixed rice), tempura, and miso soup. The mushrooms are also used in Chinese cuisine, where they are used in soups, braises, and stir-fried vegetable dishes such as Buddha's delight.
The earliest written record of shiitake cultivation is seen in the Records of Longquan County, compiled by He Zhan in 1209 during the Song dynasty in China. The description of shiitake cultivation from this literature was later adapted in a book by Japanese horticulturist Satō Chūryō in 1796, the first book on shiitake cultivation in Japan. The Japanese cultivated the mushroom by cutting shii trees with axes and placing the logs by trees that were already growing shiitake or contained shiitake spores.
Over time, new methods of cultivation were developed to meet the high demand for shiitake mushrooms in Japan. In 1914, Dr Shozaburo Minura, a mycologist, devised a method for growing shiitake on logs, allowing for cultivation outside of forest settings. Most shiitake mushrooms available in stores today are produced using mushroom bed cultivation, which offers affordable prices and year-round availability. However, log-grown shiitake, which can only be harvested 1-2 times per year, is considered organic and has a richer umami flavour and stronger aroma.

They are used in many Japanese dishes, including sukiyaki, udon, and tempura
Shiitake mushrooms are native to East Asia and are widely cultivated and consumed around the globe. They are commonly used in Japanese cuisine, including in dishes like sukiyaki, udon, and tempura.
Shiitake mushrooms are a key ingredient in sukiyaki, a popular Japanese dish. In sukiyaki, shiitake mushrooms are typically sliced and cooked with other ingredients such as bacon, tofu, and a variety of other mushrooms. The mushrooms are known to add a distinct umami flavour to the dish.
Udon is another Japanese dish that commonly features shiitake mushrooms. Udon is a type of noodle soup that can be made with a vegetarian broth, providing a satisfying and flavourful meal. The shiitake mushrooms are sliced and cooked with other ingredients such as leeks, ginger, garlic, and soy sauce, adding a rich flavour to the soup.
Shiitake mushrooms are also commonly used in tempura, a popular Japanese dish where ingredients are battered and deep-fried. When making shiitake mushroom tempura, the mushrooms are typically wiped clean, trimmed, and then coated in a light batter before being fried until crisp.
In addition to these dishes, shiitake mushrooms are also used in other Japanese recipes, such as miso soup and steamed or simmered dishes. They are a versatile ingredient that can enhance the flavour and texture of various dishes.

They are cultivated on sawdust or logs, with the latter method producing organic mushrooms
Shiitake mushrooms are cultivated on both sawdust and logs, with the latter method producing organic mushrooms. The mushrooms are native to East Asia and have been cultivated and consumed around the world for over a thousand years. They grow naturally on the decaying wood of deciduous trees, such as chestnut, maple, and sawtooth oak.
The two primary methods for cultivating shiitake mushrooms both originated in Japan and have since been adopted globally. The first method, using sawdust, was developed to increase the number of annual harvests so that fresh mushrooms are available all year round. Nutrients are mixed with the sawdust, and then shiitake mycelium is added before the mixture is placed into bags or containers. This method is more convenient for indoor storage and allows for easier control of growing conditions. It also results in shorter mushroom growing cycles, with mushrooms available for harvest in about six months.
The second method, using logs, was devised by Dr. Shozaburo Minura in 1914. It involves inoculating logs with spawn, which are actively growing mycelia that retain the genetics of the contributing fungus. Hardwood logs, such as oak, are drilled with holes and filled with either plug or sawdust spawn. The spawn is inserted into the holes and then sealed with wax to prevent drying and protect against pests. This method takes longer, with mushrooms taking more than two years to begin growing and typically only emerging twice a year.
While the sawdust method is more convenient and efficient, the log method produces organic mushrooms that are cultivated in a more natural environment. This method is still used by many Japanese shiitake farmers, contributing to the global production of shiitake mushrooms, which make up about 25% of total yearly mushroom production.

They are graded on factors such as thickness, appearance, flavour, and size
Shiitake mushrooms are native to East Asia and are cultivated and consumed around the world. They are grown in conditions similar to their natural environment, on artificial substrates or hardwood logs, such as oak. The name "shiitake" comes from the Japanese words "shii", referring to the Castanopsis tree, and "take", meaning "mushroom".
Shiitake mushrooms are graded on various factors, including thickness, appearance, flavour, and size. The grading process is essential as it determines the product's price and marketability. While there are some slight variations depending on the type of mushroom (e.g., dried vs fresh), the following are some standard criteria used for grading shiitake mushrooms:
Thickness and Size
High-grade shiitake mushrooms tend to have thicker caps with firmer flesh, while low-grade mushrooms may have thinner caps and less firm flesh. The diameter of high-grade mushrooms is generally larger, exceeding 4 cm, and they are more uniform in size. In contrast, low-grade mushrooms have smaller and more variable diameters.
Appearance
The appearance of shiitake mushrooms is a critical factor in grading. High-grade mushrooms have smooth surfaces without cracks or roughness, while low-grade mushrooms may exhibit uneven surfaces, cracks, or roughness. The colour of high-grade mushrooms is typically uniform and a dark brown or chestnut colour. In contrast, low-grade mushrooms may have uneven colouring and spots. High-grade mushrooms also possess a natural gloss on their surface, while low-grade mushrooms may appear dull.
Flavour and Aroma
The flavour and aroma of shiitake mushrooms are also considered in the grading process. High-grade mushrooms have a stronger and more unique aroma, while low-grade mushrooms may have a lighter aroma or, in some cases, an off-putting smell. The taste of high-grade mushrooms is superior, and they offer additional benefits such as enhanced nutritional value and medicinal effects.
Integrity and Freshness
High-grade shiitake mushrooms are intact, without any damage, insect bites, or mould spots. On the other hand, low-grade mushrooms may have partial damage or defects. High-grade mushrooms also maintain their natural aroma and freshness, free from mould or odour, while low-grade mushrooms may exhibit signs of deterioration.
Water Content
Water content is another factor influencing the grade of shiitake mushrooms. High-grade mushrooms have a low water content, making them suitable for long-term storage. Conversely, low-grade mushrooms have a higher water content, leading to easier deterioration.
