Shakkan-Ho Conversions to Metric and Imperial Systems

A useful utility to convert between old Japanese units (Shakkan-Ho) and the good old Metric and Imperial Systems.

Shakkan-Ho   Metric System   Imperial System
shaku (尺)
sun (寸)
bu (分)
  cm   inch
   

One shaku (尺) is approximately 30cm. One sun (寸) is about 3cm, while one bu (分) equals 3mm. As a curiosity, one ken is equivalent to 6 shaku (180cm), approximately the height of a man.

Even when Shakkan-Ho is the old system, it’s still used in Japanese martial arts for measuring the length of weapons, as well as for clothing (in which case a bu corresponds to 3.79mm) and footwear (when it corresponds to 2.4mm.) In any case, one shaku always equals to ten sun; and one sun contains always ten bu.

Three Techniques That Have Everything

O’Sensei once said that a student could learn all the basics of aikido if he practiced just three techniques: tai-no-henko, morotedori-kokyuho, and suwariwaza-kokyuho. Given the seemingly endless number of different waza and their variations, how is it possible to encompass aikido in just these three primary techniques?

Katori Shinto Ryu: Warrior Tradition

Koryu.com has finally released the all too expected book on Tenshin Shoden Katori Shinto Ryu written by Soke Risuke Otake. For a long time, “The Deity and the Sword” has been listed for up to USD500 in some online stores, so for all of you that didn’t want to spend that lot of money this is great news. This one-volume 336-pager is based on the earlier 3-volume work, reedited and redesigned, and for a much cheaper price.

This book contains a lot on history of the School, the techniques and the strategy for which it is famous. Some extra information about the more esoteric principles (such as the kuji in) can also be found in this great work.

El Evangelio de Tux, desenterrado

Cada generación tiene una mitología. Cada milenio tiene un día del Juicio Final.

Cada leyenda lleva el nudo de la distorsión hasta que el orador se funde. Un grupo de arqueólogos en la Universidad de Helsinki descubrieron hoy lo que pueden ser las escrituras más antiguas conocidas del Culto de Tux, una secta religiosa fanática que floreció durante la temprana Era del Silicio, alrededor del amanecer del tercer milenio DC…
