Hi Guthrie,
I was looking for something on Google and was curious about this link.
I am sure you already know about Doshinkan but for those who don't, here is some information...
This style is traditional, it means no fighting. Nihon kumite is practiced analyzing katas only. There are about 200 forms but about 70 are used frequently.
There is no physical training like in sport styles. I spent a few years practicing different sports when I was young. Shotokan and Kyokushin in Poland and Wado Ryu in England. These first two styles are very physically demanding, with technical training at the end. Not many katas in Kyokushin... If someone wants to get into great fighting shape, these two are perfect for it. I have great memories from both of them.
I switched to Doshinkan after I found out that my first childhood instructor changed to Doshinkan. Plus my body was aching from injuries...
This style is more suited for mature people who don't chase after belts and competitions. The only person who can give you a belt is a Grand Master, Hanshi, 10 Dan.
It means that even 8th Dan cannot advance anyone. This usually doesn't sit well with Western society... I frequently meet 6-7 year olds running around with black belts (Taekwondo)...
I knew a very well trained guy who was wearing a white belt for over 10 years because he didn't have money to travel to meet Hanshi. When he finally met him, his advancement was up to 4th kyu...
Belts are totally dependent on Master's vision of your progress... There are exams sometimes but you are judged not just according to your technical skill level... For a black belt you may be asked to perform a kata (1 out of 70...)... or he gives you a few to choose from.
You will need to get internally motivated to get fit. There is a very detailed stretching of all joints performed after a few minutes of meditation. Similar to Tai Chi. All commends are in Japanese, no shoes. There are no beginner's lessons. Everyone trains together. This has huge benefits, if you can't see instructor's movements, just look at the guy next to you with a higher belt.
After meditation and stretching instructor precedes to short combinations repeated many times. These are in preparation for a full kata. Those who know many katas, can immediately figure out which kata is going to be practiced during training... At the end, kata is repeated many times, 10-20 times. It's a great way to learn all the moves. Another beneficial thing is that every move is explained and practiced in detail. It means that advanced practitioners don't just mindlessly repeat moves but know exactly what happens with their bodies and those who attack them at all times. You imagine opponents attacking you not just kick, punch and block in order... Some katas are pretty long, 60-70 moves... If you put your heart into it, you will reap great benefits. If you don't, you will eventually get your black belt anyway... After years of training and meeting Hanshi. You may feel crappy about it, though.
This style is not about getting uke or wazari, it's about ippon only. Someone who attacks well trained guy in this style will get seriously hurt... Kicks and punches are executed with full power, it's why there is no kumite. Like late Hanshi said:"It's too dangerous, someone could die... "
There is no "showing" that you can hurt someone by slowing down or withdrawing your punch. It's a full blast assault to finish the fight with one technique. Always aiming a few inches past the target for maximum damage... It is completely different mind set, you don't worry about disqualification for brutal fighting or illegal technique... Everything is legal in a street fight. They always used to say that UFC has no rules. That's a lie. Eye gauging? Cupping ears with full power? Breaking a knee with a first opportunity? That's all taught in traditional martial arts...
To summarize, it takes much longer to become advanced in true traditional style, no doubt. If you want to fight bullies, defend yourself or compete, Shotokan and Kyokushin are great for it. So are other styles of martial arts. And it won't even take that long if your instructor pushes you hard and you dedicate yourself fully.
Traditional style is more about lifestyle not physical prowess.
Doshinkan is not advertised because not many people want this kind of structure. No belt exams every 3 months? That's shocking for people around here (US)...
I've got to 1st Kyu in Doshinkan and old Hanshi passed away... I practiced it for a few years after but had no chance to meet new Hanshi at that time. It means, I will have brown belt in this style for the rest of my life...

You need to start from white belt, even if you have high belts from other styles. Plus, first 4 belts are white, anyway...
Like I said, it's a lifestyle, who cares about belts. Promotions are usually once a year. If you feel that there is no way for you to get to a black belt because of age or physical limitations, that's a great option for you. A lot of highly educated people practice this style... It may take 6 years or more but no one will make you do alligators across the gym...
There is an anual meet in Southern Germany in July. 1 week long. 2 trainings a day, outdoors. Great experience. In 90-ties it was around 300 practitioners every year...
Due to surgeries and serious injuries I don't practice any martial art anymore. I obused my body too much when I was young... Too bad, I definitely had a spirit for it. Still have...
