“The school where the Spirit is refined”

Seishinkan is a martial arts organization dedicated to the dissemination and teaching of Budo 武道. Founded on May 1, 1987, by Osvaldo Rodriguez Sensei who has devoted a lifetime to the training, research and teaching of martial arts as a philosophy of life that helps human growth and development. Currently, with 30 years of operation, it is constituted as an organization in its own right, with representatives in different parts of Chile and Europe.

Seishinkan was recognized by Okinawa Japan through Grand Master Angi Uezu and from 1992 to 2017 it worked hard on the essential principles of the Isshin Ryu Karate & Kobudo under his direction.

Seishin has his bases in the systematic practice of Okinawan war arts, which in the modern era have become systems of the integral evolution of the human being through the practice of Budō 武 道. This corresponds to the term that encompasses the technical knowledge of contemporary Japanese / Okinawan martial arts and a certain set of ethical norms that govern the behaviour of its practitioners in a similar way to what Bushido 武士道 represented for the ancient samurai.

Seishin uses this systematic practice as a way of overcoming and developing its practitioners in its three stages: Body, Mind and Spirit (Shin-Gi-Tai).

The Kanjis that make up the idea and true feeling of SEISHIN are translated as follows:SEISHIN


Refined, pure authentic.


Whose meaning is related to spirit. soul, with the superior mind.

The daily operation of our school is constantly guided and supported by the Seishin philosophy, based on three very important oriental concepts:

  • The Wabi Sabi 侘 寂: imperfect but happy.
  • Ichi Go Ichi E 一期一会:  every moment is unique.
  • Zen 禪 Spirit: the moment is now

Consolidating these concepts, Seishinkan can be translated as “The School where the Spirit is refined”, through a disciplined practice for our body, systematic for our mind, and hard for our spirit.



SEISHINKAN BUDO: The Institutional Vision & Mission


Seishinkan aims to become a recognised and distinguished martial arts organization, nationally and internationally, for the high standards in human, technical and professional quality of all its members.
