A Kyushindo-style badge/logo has been used since I started; judging by old photographs, it has been used since the late 1950s.

The Badge photo is from a Pathe News film made in Highgate in 1960 showing George Mayo and his judo club.

The 1980s shield-shaped badge and a round variation are shown below:

The shield logo above is derived from a large cloth badge I bought after gaining my black belt. Around the same time, I obtained the white badge as a sticker from the Banstead club.

When I commissioned a cloth badge, the supplier had to produce artwork from a photo of the older badge and the sticker (for Kanji).

Two batches of cloth badges (on the right in the photo) were produced at the Romsey Club. The first batch was close to the colour of the 1980s badge, but the second batch was a darker blue. Unfortunately, producing small batches is now prohibitively expensive and no longer available.

What do the symbols (Kanji) at the top actually say – Kyu Shin Do or something else? I have not been able to find a definitive answer.

I hope it’s not like the urban legend, where a Chinese martial art developed in the West used some symbols that turned out to be obtained from a takeaway menu.

The other branding relates to the flashes on the belt denoting Dan grades. Japanese Karate typically uses a stripe to denote each Dan grade achieved. In Kyushindo Karate, moons / crescents are used. They are shown below for Romsey, but variations in the circle and the use of red instead of yellow are used in other areas.

Some use all moons – 1 for each Dan grade (eg. Bristol), and others use a moon for Black belt and then a crescent for each Dan grade (such as Romsey)
