About this source
What it is
This document, dated December 2005, is a presentation written by Shihan Gosho Motoharu of the Gosho Ha Hyoho Niten Ichi Ryu school for the Brazilian Portuguese edition of Miyamoto Musashi's treatise, the Book of Five Rings. It includes a photograph of two men and handwritten Japanese calligraphy with red seal stamps alongside the printed Portuguese text.
Why it matters
Musashi wrote the Book of Five Rings as a guide to swordsmanship and strategy. This later presentation, written centuries after his death, shows how his book continued to be translated, studied, and introduced to new readers around the world, including in Brazil through the efforts of figures like Jorge Kishikawa and Gosho Motoharu.
