Our Covid-19 Measures to Keep You Safe

How We Protect You from Covid-19 during Classes:

1. We will look at the Governor’s guidelines for gym openings and follow them strictly.

    Right now that entails non-contact social distancing Outdoor Classes that begin Mid-June.

2. We will continue with Zoom classes from the dojo for overseas folks and those that are tied up at work, or those that don’t want to get out of the house yet. 

3. After cleaning the air duct system in February I installed a UVC light in the dojo air duct system to control mold and bacteria. Scientific documents also claim that this also kills MRS and SARS viruses. Covid-19 is a SARS virus, but there haven’t been any tests conducted on it yet. I also ordered two additional UV-C lights for use in the dojo after class.

4. We will look at other virus killings/neutralizing measures we can implement in the dojo. 

   – I will add a second UVC light in the air duct system just in case.

   – I will use MERV-11 air filters in the dojo to filter out pollen and dust reducing the work of the UVC lights. 

5. We will practice outdoors and in the dojo with masks on, maybe with gloves once contact resumes?

6. Non-contact kumite and bunkai can still be done to get up a good workout and keep your timing.

7. Hand sanitizer or handwashing will be mandatory.

    (Note: I need to put Teflon tape on the utility sink couplings so we can use that, too.)

8. There is abundant disinfectant/virucide to clean the floor before and after each class. The virucide is most effective when left to dry on the mats. I will get a sprayer so we can spray before and after class.

9. What are the Class times when the dojo reopens?

    We will see how we proceed.

The Meaning of Our Karate Patches

* The Kanji on our left Chest:


This spells out Shidokan means “Warrior Way”, “Right Way”, “Heart Way” or “Gentleman’s Way”. One Japanese woman recently told me it meant Samurai Way. My preferred includes the complete exoteric meanings: Warrior Path.

The first character reads “Shi” interpreted as Heart, Central, Correct, Gentleman, Warrior or Samurai.
The second character you will see in many martial arts patches and names as “Do” means way or path.
The third character is also prevalent on many Martial Arts patches and names. “Kan” means place, refering to Dojo (a different character). The Japanese refer to “kan” as a restaurant or eating place.

* The colorful Beikoku Shidokan Symbol we wear on the left shoulder:

The red and black colors represent the intertwined aspirations of the highest belt ranks attainable in Shidokan Karate.  The black belt and the red belt for 9th and 10th Dans.

The circle represents nature’s circular movements in front of a balance or old-style weighing device used even today in small

Okinawan stores to weigh produce. Balances in stores are nearly all electrical now. So you may be unfamiliar with an old-style balance. The common American symbol of Justice is a blindfolded woman holding an old style balance in her hand.

The Beikoku Shidokan Symbol is very similar to Master Akiyoshi Shiroma’s Nishihara Shidokan Dojo.
Iha and Shiroma are cousins. Shiromas symbol has the Kanji “Nishihara Dojo” at the bottom where we have Beikoku Shidokan.

The Kanji at the bottom have some similar characters as those on our chest patch.
The first character is “Bei” meaning rice.
The second is “koku” representing country.
Did you know that “Beikoku” or Rice Country is what most Asian countries call the United States?
The following three kanji characters spell Shidokan.

So our patch represents American Shidokan. When Sensei Iha was promoted to 10th Degree in 2001 he named his style Beikoku Shidokan in honor of his instructor Katsuya Miyahira. Prior to that we just wore the Shidokan patch on our chest.
