How should I wash the Keikogi and Hakama?

The following are some important informantion to take good care of your Kendogi and Hakama:

  • You should use cold water to wash both Keikogi and Hakama.
  • You should never wash with other clothes, as the color from the indigo dye will come out and stain other clothes.
  • You should also NEVER place them in the dryer, as it will shrink in a large scale.
  • Do not use washer to wash them.
  • After washing the Hakama, before it is dried, fold to its original format and hang dry on the shadow or dry area.
  • Do not expose to direct sunlight.

What is the best way to avoid breaking the Shinai?

As you know, Shinais are made of bamboo (except for the carbon graphite Shinais), which will eventually break after extensive usage. However, some precautions may be taken to extend the life of a Shinai.

  • After purchasing a Shinai, disassemble the leather parts (if you purchased a complete set), and apply salad oil (Olive Oil gives the best performance) on all sides of the bamboo using a paper towel or some cloth. Let it sit for a day in order for the oil to be absorbed by the bamboo. Wipe off all excess oil from the bamboo. This will give a better color and endurance for the bomboo.
  • Rotate the bamboo every 3 5 practices. The side of the Shinai that strikes the opponent is the side that gets the most damage. By rotating the bamboo, the load is evenly balanced across the 4 pieces of bamboo.
What is the meaning of Bu (e.g. 1.0 Bu, 1.2 Bu, 1.5 Bu, 2 Bu) on the Hand stitched Bogus?
  Bu is a measurement from Japan that represents to about 3 mm.  Most Hand stitched Bogus are 1.0 Bu, 1.2 Bu and 1.5 Bu.  There used to be Bogus with larger stitchings than 2 Bu, however we do not see those kind anymore.
What is the meaning of stitching (e.g. 2 mm, 3 mm) on the Machine stitched Bogus?
  The millimeter measurement on the machine stitched bogus are the approximate distance between the stitching on the Bogu.  Smaller the number means that the stitching is spaced closer, giving better resistance to the strikes.  However, some people prefer the larger stitches, as it makes the Bogu softer.
What size shinai should I use?

In Kendo, the Shinai sizes are determined by the age and the gender of the person practicing Kendo. This is determined by the IKF (International Kendo Federation) rules and regulations. The weight and the length of the Shinai is measured at official competitions. Please refer below to the IKF Official regulations:
