About Hiraide Oil Store's Rapeseed Oil
Our Rapeseed Oil is a high-quality rapeseed oil based on the principle of "Natural oil with a nice fragrance and delicious flavor as great as possible."
Made from the highest quality of Japan's domestic rapeseed,
The oil is processed with the traditional method called "Tamajime" without chemical processing and done by carefully squeezing the rapeseed using weight.
The quality is well evaluated by many people, and it is now the most popular oil product of Kawashima The Japan Store.
Generally, rapeseed oil is considered to be unsuitable to be consumed raw (without heating) because it has a peculiarity.
However, the Hiraide Oil Store's Rapeseed Oil has no peculiarity and can be used for dressings, too.
It also has good heat stability compared to other oils, so this oil is perfect for making fried dishes.
Rapeseed oil is rich in oleic acid, that classified as a mono-unsaturated fatty acid, one of the fatty acids which are the main component of vegetable oils.
Oleic acid is said to have the effect of reducing bad cholesterol that causes arteriosclerosis without reducing good cholesterol.
It has stronger smell and color pigments than other oil because of the natural tocopherol (class of vitamin E compounds which have antioxidant activity) and natural chlorophyll and carotene dissolved in the oil that extracted from the "Tamajime" method.
We are using the pesticide-free "Kizakino" Rapeseed from Hokkaido Prefecture, Japan.
Through the "Tamajime" method, we are able to squeeze a very beautiful golden color oil.
The squeezed oil is slowly filtered using the luxurious handmade paper called washi. Then, it is hand-packed in a container to make the rapeseed oil that is rich in flavor.
This oil is a natural and highly safe oil.
It is a valuable item because it is hand-squeezed product.
About The Raw Material: Rapeseed
The origin of the raw material for this oil: rapeseed is from Hokkaido Prefecture or Aomori Prefecture, Japan.
No radioactive material was detected in either raw material.
Picture Below is The Report on Radioactivity Measurement of both raw materials,
published by Fukushima Technology Center in 17th July 2015.
The Hiraide Oil Store's Rapeseed Oil is characterized by the seed's richness and umami flavor because the seed was plenty bathed under the grace of the sun.
It has refreshing flavor and brings out the deliciousness of every dish.
It will able to finish dishes like stir-fry or tempura dishes perfectly and stands out the material's goodness.
If you used rapeseed oil as the substitute of butter in the same amount when making sweets,
the sweets will have a moist and delicious texture.
You can use it to make bread, cake and cookies too.
We received lots of good comments from consumer who purchased the product, thank you!
I mainly use it to make sweets, but the taste and flavor are completely different.
The color is darker than the usual rapeseed oil, I felt that this oil is natural as it was.
When used to make stir-fry dishes, it is easy to use and loses useless fat and finishes deliciously.
This oil is good as I expected. It doesn't feel so oily and looks good for my stomach. I will no longer use any salad oil in supermarket's sales or department store's sales.
It has a pleasant smell when it is heated, but there is nothing like an unusual smell in the finished food. Instead of it, it boosts the flavor, and the dish finishes greatly and delicious.
Now, I can't eat the ready served side dishes.
This rapeseed oil can be use for frying, stir-frying, and grilling. Everything is for self-catering. It's very delicious.
My child has an atopy. When I started to review our meals, I learned that rapeseed oil is good for atopy.
I use it for cooking and sweets making. If used for fried food, it's crispy and very delicious. I think that this price is a good value also in terms of quantity.
Rapeseed Oil - Content Variations
Introducing How The Rapeseed Oil was Made
How The Rapeseed Oil was Made
Step 1. Roasting
The first step is roasting the raw material (rapeseed).
The rapeseed is roasted in a bowl heated with firewood.
It takes about 30 minutes to dry the rapeseed. This is done while adjusting the heat with the amount of the firewood.
About 50 kg of rapeseed can be roasted in one pot at one time. From that, the amount of oil squeezed is up to 15 to 18 liters.
If the seed is not well roasted, it will not squeeze enough oil.
But on the contrary, if the seed is over-roasted, it will cause bitterness.
So when the roasting takes place, the workers will check the seed's condition periodically while mashing some of the seed with their fingers.
Step 2. Cleaning
The next step is removing impurities from the rapeseed.
Once the roasting is done, the rapeseed is put in a sifter. This step is to remove the unnecessary stuff from the rapeseed.
Step 3. Grinding
The third step is to grind the seeds using the roller in a rolling mill. The grinding step will tear the seed's skin.
Step 4. Steaming
The fourth step is put the grinded rapeseed in a wooden pail and place it on the top of special steamer.
By using the heat from burned firewood, the steam vapor will appear.
Set the pail on the top of the steamer.
There are small holes at the bottom of the pail, so the steam can come from underneath it. It is an arrangement so the steam would not cut through the pail.
The steaming is done while adjusting the heat from the firewood.
By steaming the seed, the oil will expand and make the oil squeezing step much easier.
After 5 minutes of steaming passes and the entire pail are full with the steam vapor, it shows a good steamed sign.
Step 5. Break
This step is cooling down the steamed rapeseed, it's called break.
At this stage, the workers spread the steamed rapeseed to cool off the steam. Once the steam blows away, they will place a wood-made oil filtering mat underneath a pail and packed the rapeseed tightly with the mat.
This oil filtering mat is one of the essential tools for the traditional oil squeezing and characterized because it was made with human hands.
These handmade mats are suitable for oil squeezing because they have moderate strength and softness, and there is no excess oil other than rapeseed oil itself.
It is a custom-made product by a wig maker, and currently, there are only a limited number of places that can be manufactured nationwide Japan.
The workers wil put the Tamajime ball (heavy, metal-made weight to squeeze the oil) to the wood-made oil filtering mat filled with the rapeseed.
By stuffing the rapeseed while applying moderate pressure from the Tamajime ball, the oil becomes easier to squeeze.
Step 6. Squeezing
The workers put the pail packed with mat filled with steamed rapeseed to the "Tamajime" squeezing machine.
This machine has a ball. The workers then add weight to the ball slowly while the oil is being squeezed.
While carefully making fine adjustments, 1 to 2 tons of weight is added to the ball.
After a while, due to the weight of the ball, a fine and golden oil overflows from the pail.
The method of squeezing the oil by the weight of the ball is called "Tamajime" method.
Currently, the factories which produce by this "Tamajime" method is rare. There only are a few in this country.
The freshly squeezed oil has a thick, dark color. It also has a strong aroma of rapeseed.
The residue of squeezed rapeseed is used for farming as organic fertilizer.
Step 7. Filtering
Hiraide Oil Store uses the specially hand-made, cylindrical paper filters (washi) to filter the rapeseed oil.
Place open the cylindrical handmade paper in a grid-like container and pour rapeseed oil into it.
They then wait until the oil to be naturally filtered while taking time slowly.
Using hand-made paper for filtering is a unique Japanese tradition.
When the oil comes out from the filter, the rapeseed oil is done.
Step 8. Bottling and Labeling
The freshly made oil is gathered in a small stainless tank.
The bottling step is all done by hands.
At last, the workers will stick the label on the bottle, and now the oil product is ready to go.
Normally, there are no pre-made stocks in the Hiraide Oil Store. The products that have been completed on that day are shipped immediately. This is how The Hiraide Oil Store make their oil.
[Manufacturer's Interview] Hiraide Oil Store
"I wonder that the best product will be the oil that squeezed as it is" as Mr. Hiraide talked in an interview in this article.
If we are about to pursue efficiency, the quality of oil will be lost by any means. So we are continuing to make oil using the traditional method to maintain the oil's quality.

Hiraide Oil Store's Principle
The Hiraide Oil Store's principle is to make "Natural oil with a nice fragrance and delicious flavor as great as possible". This principle has not changed since the early Showa Era (1926–1989).
"Once I use the rapeseed oil from Hiraide Oil Store, I can not use other oils."
We have many voices like that.
Most of the edible oils currently sold in supermarkets and department stores are extracted by chemical processing in an efficient way.
By applying high temperature and pressure and chemical treatments such as deoxygenation, degumming, and deodorization, that is possible to extract cheap rapeseed oil with uniform quality efficiently and without waste.
However, in this way, the oil will deteriorate.
Also, the mellow and golden shades of rapeseed oil are greatly diminished.
The rapeseed oil from Hiraide Oil Store uses rapeseed from Hokkaido Prefecture for almost all the raw materials. The rapeseed used are only the one with the big grain, and have a moisture content of around 8%.
There are 3 "Tamajime" balls in the oil mill, and two to three workers squeezing the rapeseed everyday.
About The Traditional Squeezing Method: Tamajime Method
It is method to squeeze oil slowly over time under low pressure and normal temperature using special machine called the "Tamajime" squeezing machine.
The history of "Tamajime" method is old,
And it seems that the manufacturing method had already been established in the middle of the Edo period.
In the past, many manufacturer used the "Tamajime" method, but now only a few small and medium sized companies are keeping the tradition.
Oil made from the "Tamajime" mehode is a very valuable oil, it is less than 1% in terms of overall share.
The generally distributed rapeseed oil uses petroleum solvents and chemicals for deodorization and decolorization, etc.
Therefore, it is not very usable.
On the other hand, "Tamajime" method does not generate frictional heat because it is squeezed for a long time under low pressure and at normal temperature. So there is no need to do unnecessary processing. The finished product is an extra virgin oil because it is simply a filtered squeezed oil.
It is a product that is hard to enter the ordinary supermarkets.
Recommended Way to Use Rapeseed Oil

Message from Manufacturer
– Mr. Yuichi Hiraide
The daily intake of oil needed by Japanese adults is roughly 1 to 2 tablespoons.
This small amount of intake affects the body for a long time.
(Trans-fatty acid by coconut oil that is currently a popular issue).
By producing this oil, we would like you to take real oil for daily health improvement.
The Hiraide Oil Shop was established in 1842.
Initially, we sells silk fabrics and cereals, and has started selling Rapeseed Oil since the Meiji Era (1868).
Mr. Yuichi Hirade, the current president, is the sixth generation owner of Hiraide Oil Store.
“Rapeseed” is a member of the family Brassicaceae (cabbage family of plants), and also called as rape.
In addition, it is said that rapeseed also include as plants that the fruit can be used for oil extraction.
Originally in Japan, it is called “Vegetable’s Flower” which means by the seed of vegetables.
The origin of rapeseed is around West Asia and Northern Europe,
Since ancient times it has been grown as a vegetable/plant for oil extraction.
In Japan, rapeseed is eaten as a vegetable. And in the Edo period, rapeseed has been widely grown to use its oil for cooking and eating.
The Difference Between Rapeseed Oil and Canola Oil
Rapeseed oil is an oil that can be extracted mainly from the seeds of Brassica napus.
In East Asia, rapeseed oil has been used routinely since ancient times, and the rapeseed self-sufficiency rate in Japan was 100%.
Rapeseed oil contains ingredients called "erucic acid" and "glucosinolate".
In the United States, where people consume a large amount of oil in daily meal, it is said that there is a risk of adverse effects on the body if people consume an excessive amount of oil. Therefore, they prohibit some edible oil.
Therefore, in the 1970s, Canadian agricultural researchers carried out quality improvement and created "Canola Oil" as a new rapeseed with almost no erucic acid and glucosinolate.
Why Rapeseed Oil is Said to be Dangerous for Our Body?
Originally, rapeseed oil takes time to produce. Moreover, it is possible to take all the oil contained in rapeseed.
In order to produce oil from imported rapeseed oil as efficiently as possible, major oil manufacturers are extracting 99% of rapeseed oil using a petroleum-based solvent called "hexane".
Hexane is a component also contained in gasoline.
It may irritate human skin and respiratory organs, and may adversely affect reproductive function and the fetus.
In addition, rapeseed oil has a pungent smell that pokes through the nose, so you have to deodorize the oil to eat it.
To deodorize the oil, it is necessary to heat the oil to a high temperature of 200 °C or higher.
At that time, the "trans fatty acid" that is harmful to human body is generated.
Trans-fatty acid is a component of oil product when hydrogen is added to vegetable oil,
Many trans-fatty acid are included in shortenings that are also used in commercial margarine, bread and cakes.
This trans-fatty acid has already been recognized as a substance that adversely affects the human body, which can be a cause of cancer and arteriosclerosis.
Some countries have regulated the oil intake for the body, although it is not regulated in Japan.
There are many cheap rapeseed oils sold in the market.
But you don’t need to worry to consume the rapeseed oil if it is made by a manufacturer that follows the traditional squeezing production method, while taking time and effort to make the rapeseed oil, and doesn’t treat the product with chemicals.
The rapeseed oil from Hiraide Oil Store is made by squeezing method.
Because oil is an essential material for your daily consumption, you want to use something safe for your health.
What is the important point of choosing the safe rapeseed oil?
● Use non-genetically modified raw material = The Hiraide Oil Shop use domestically grown rapeseed varieties.
● Do not use petroleum-based chemical solvents in oil extraction = The Hiraide Oil Store adopt the traditional squeeze manufacturing method, “Tamajime” method.
The rapeseed oil made from domestically produced rapeseed and manufactured domestically by squeezing method is a kind of rapeseed that you can safely use.
How to Identify Safe Rapeseed Oil is Focuses on Domestic Products and Processes
Currently, there are many rapeseed varieties in Japan that do not contain erucic acid.
Because the rapeseed grown domestically in Japan does not use genetic modification technology, it is safe to say that rapeseed oil made from domestic raw materials is safe.
Varieties such as "Asakanonanae", "Kizakinohana" and "Nana-kibu" have been developed. The oil made from Kizakino rapeseed is rich in flavor and is especially said to be the best rapeseed oil.
The raw material of Japanese Rapeseed Oil from Hiraide Oil Store uses 100% of this Kizakino rapeseed.
