Senko(Incense Stick)

Senko(Incense Stick)

Born in the liberal city of Sakai, Japan's traditional scent senko, or incense stick, has now grown into a fragrant work of art.

Sakai Made Japan's First Senko Sticks

There are many theories about the beginning of the senko industry in Japan. The only thing certain is that its manufacturing method had already come from China by the 16th century and Sakai was its manufacturing center.
In those days Sakai was Japan's largest free port allowed to trade with the world. Missionaries wrote back home describing Sakai as "a large and prosperous city, flourishing in business, just like a public market place where people come and go constantly."
Sakai became the center of senko production because it had easy access to most of the raw materials imported from overseas, and out of the necessity to supply the temples existing in and around Sakai. Ranking third, following Kyoto and Nara in the number of Buddhist temples, Sakai is referred to as the "Buddhist Capital of Sennan".
Sakai's senko stands out from the rest because of its blend of the finest, natural ingredients. It is also referred to as a fragrant work of art. Recognizing the natural fragrance's healing factors, the medical profession has been using it as a form of treatment, while the manufacturers of room fresheners are using it in indoor aromatics.

How Senko Sticks Are Made

  1. Grinding/Mixing
    Natural ingredients such as agallochum, sandalwood, clove, and cinnamon are pulverized and mixed with 15 to 20 different home blend essences according to a formula which has been passed down through the centuries.

  2. Kneading
    In order to ensure even quality, the powder is sifted through a sieve, and then kneaded into a clay form.

  3. Molding
    MoldingOnce the mixture turns into a clay form, it is placed in a compressor-type molding machine to make 10 kg pieces of incense. Each piece is wrapped up in plastic, cooled by water and left overnight to mature.

  4. Pushing out/ Tray cutting
    Pushing out/ Tray cuttingEach piece is placed into an extruding machine and pushed through. When the thin strings of senko come out, the skilled craftsman receives them on a tray and cuts them into a uniform length.

  5. Moving
    The senko sticks are moved skillfully from the tray to drying boards with a bamboo spatula and by hand. Crooked sticks are thrown out at this point.

  6. Cutting
    CuttingAll the senko sticks are cut into the same length using a rotary cutter.

  7. Drying
    DryingSenko is best dried naturally.
    It dries in a few days during summer and over 10 days in winter.

  8. Bending prevention
    During the time the senko sticks are left out to dry, they are frequently pushed closer together to prevent bending. The next step is to place the drying boards on top of each other to further prevent bending.

  9. Tying
    TyingAll the senko sticks are checked as they are gathered into a uniform bundle and tied together to prevent them from bending.

  10. Packing
    The senko sticks are inspected, wrapped and placed in boxes.
