Product Features

● Rich flavor nurtured by the waters of Shiretoko, a World Heritage Site

The waters off the Shiretoko Peninsula where Rausu kelp grows are special seas that are constantly fed with mineral-rich nutrients from drift ice from the continent and rivers such as the Rausu River.

Rausu kelp, grown in this fertile environment, contains the richest umami components of the three major dashi kelps, and boasts a powerful flavor worthy of its name as the "king of kelp."

● Thick and soft, with an exquisite texture

The leaves of Rausu kelp are about 15cm wide and thick, yet have soft fibers, which is a distinctive feature of the plant.

Not only is it great for making soup stock, but it's also great for kelp pickling and simmered dishes.

After making the soup stock, you can enjoy the kelp to the fullest by making it into tsukudani or eating it as a snack.

● Fragrant and rich flavor

Rausu kelp stock has a soft yellow color and stands out with its strong kelp aroma and rich sweetness.

It is ideal for dishes where you want to fully enjoy the flavor of kelp, such as miso soup, noodle soup, and hot pot dishes.

Even a small amount of seasoning can enhance the flavor of the ingredients, making the dish much more delicious.

● Founded in 1871, with over 150 years of tradition and trust

Okui Kaiseido is a long-established kelp store founded in 1871 in Tsuruga City, Fukui Prefecture.

The company has a strong reputation for its discerning eye and has been a supplier to the head temples of Eiheiji and Sojiji, and has supplied kelp to Kyoto's finest restaurants for generations, including Hoshigaoka Saryo, which was run by Kitaoji Rosanjin.

● Nutritious "sea vegetables"

Kelp is a highly nutritious alkaline food, so much so that it is called the "vegetable of the sea."

It contains a balanced amount of dietary fiber, vitamins, and minerals, and alginic acid, a type of dietary fiber, is said to help regulate cholesterol levels.

It is also a recommended food for health-conscious people.

How to eat

● Basic method of making dashi

A good rule of thumb is to use about 20g of kelp per liter of water.

Lightly wipe the surface of the kelp with a tightly wrung out wet cloth, then soak it in water and leave for 30 minutes to an hour, then put it on low heat and remove the kelp just before it boils.

The rich and fragrant Rausu kelp stock is now complete.

● Cold brew is also recommended.

Simply add about 20g of kelp to 1 liter of cold water and leave it in the refrigerator overnight (about 8 hours).

You can easily enjoy a mellow and rich soup stock.

● Perfect for these dishes

Miso soup: The rich flavor blends beautifully with the miso.

Noodle soup: Add light soy sauce and salt to the dashi to make authentic noodle soup.

Hotpot: Enjoy the powerful broth that stands up to strongly seasoned hotpot dishes such as soy sauce hotpot and miso hotpot.

Konbu-jime: Fresh sashimi is sandwiched between Rausu konbu seaweed and left to sit overnight, resulting in a luxurious dish that is infused with a refined flavor.

Cooked rice: If you make a stock using Rausu kelp and cook cooked rice with that stock, the result will be fluffy and shiny.

After making the soup stock, the kelp can also be enjoyed as tsukudani or simmered dishes.

Frequently asked questions

Q. What is the difference between Rausu kelp and other kelp?

A. Rausu kelp is characterized by the richest and most powerful flavor of the three major dashi kelps (ma kelp, Rishiri kelp, and Rausu kelp).

Perfect for those who want to enjoy the rich flavor of kelp.

Q. Can I still eat the kelp after making soup stock?

A. Yes, Rausu kelp has soft fibers, so it can be enjoyed even after making soup stock.

Use it in a variety of dishes, such as simmering it in soy sauce, mirin, and sake to make tsukudani, or slicing it into thin strips to use as an ingredient in rice dishes.

Q. What is the white powder on the surface of kelp? Should I wash it off?

A. The white powder on the surface of kelp is an umami component of an amino acid called "mannitol."

Do not rinse, use as is.

If you are concerned about dirt on the surface, simply wipe it with a damp cloth that has been wrung out tightly.

Q. What kind of food does it go well with?

Founded over 150 years ago, our history is built on kelp

The year was 1871 (the fourth year of the Meiji era).

The history of Okui Kaiseido began when Okui Hango, a samurai who lost his stipend when the feudal domains were abolished and prefectures were established, noticed the kelp being unloaded at Tsuruga Port.

At that time, Tsuruga was a key trading point for the Kitamaebune ships that connected Hokkaido with Kyoto and Osaka.

Hokkaido's new kelp, harvested in the summer, was unloaded one after another at the port of Tsuruga in late autumn.

In the snowy Hokuriku region, it is not possible to transport cargo in winter, so the kelp ends up spending the winter in the storehouses in Tsuruga.

And then spring.

The kelp tasted before shipping had undergone an astonishing transformation.

The roughness and impurities of the new kelp had disappeared, and it had been transformed into a product with outstanding umami flavor.

The kelp is left to rest in the storehouse to deepen its flavor.

It is said that the technique known as "Kurai" that is passed down in Tsuruga was born in this way.

The first generation Hango was one of the first to start dealing in this high-quality kelp, and he also started processing and manufacturing it, laying the foundation for the kelp business.

During the time of the second generation owner, Tatsunosuke, the company received permission to serve as an official supplier to Eiheiji Temple, and began doing business with famous restaurants in Kyoto.

It was around this time that we began doing business with Hoshioka Saryo, run by the renowned gourmet Kitaoji Rosanjin.

The traditional "Kurai" manufacturing method was once on the verge of disappearing due to the development of transportation.

However, Okui Kaiseido has built a dedicated warehouse equipped with a modern temperature and humidity control system, and has passed this technology down to the present day.

We have been collecting Rishiri kelp from Kafukahama on Rebun Island every year since 1989.

The current fourth-generation head of the family, Takashi Okui, says, "I have never gone into business with the intention of creating a brand.

"You can only gain trust by doing the work you do on the ground up," he says.

True to its name, Okui Kaiseido's kelp continues to be chosen by high-end restaurants throughout Japan, including Kyoto, the vegetarian cuisine of temples such as Eiheiji and Sojiji, and food lovers throughout the country.

Kelp is breathing.

The way it ages over time in the cool storehouse is just like wine.

Ingredients grown by nature are prepared with time and human skill.

This philosophy has been passed down unchanged for over 150 years.
