大東流・Daito-ryu / Six Principles of Training / Rei

Main ideas / lessons conveyed

• The video is the first installment in a series explaining the “Six Principles of Training” from Daito-ryu (大東流), focusing today on “Rei” (礼)—understood as correct formal personal conduct.
• “Rei” is more than polite behavior: it is a historically grounded practice meant to:
  • Smooth social and interpersonal relationships
  • Reduce conflict/strife
  • Prevent escalation by encouraging calm, controlled conduct
  • Preserve the spiritual mindset of a traditional warrior, which continues to inform training today
• The core practical outcome of studying “Rei” is heightened situational awareness, supporting personal safety and readiness during training and interactions.
• The instructor stresses that for foreigners, the ceremonial aspect may be more noticeable at first, but the training also teaches how to respond safely and appropriately in real dojo situations, even with language/cultural barriers.

Concepts explained (with key examples)

1) What “Rei” means

• “Rei” is translated variously as: etiquette, manners, courtesy, decorum, respect, propriety.
• The instructor emphasizes translation difficulty: many Japanese cultural terms don’t map cleanly to a single English word; meanings often fall between multiple options.
• Related lexicon terms mentioned:
  • Protocol (ceremonial sequence/behavior rules)
  • Cultural artifact (a practice valued for preserving cultural history and teaching identity—not because it directly functions in battle)

2) “Rei” historically functioned to prevent conflict

• Historically in Japan, formal conduct “lubricated” relationships and reduced fights.
• The instructor’s interpretation: even when people weren’t “offended,” conflict could erupt because disrespect created an excuse or trigger for violence—so proper conduct removes those triggers.

3) “Rei” supports martial aims indirectly

• The instructor distinguishes:
  • “Rei” is not directly about making techniques work (no direct “relevance to technique performance”).
  • But it strongly informs kata, especially how practitioners stand, compose themselves, and move at the beginning and end.
• Martial implication: conduct should avoid adding “fuel to the fire”—by either de-escalating or preventing escalation through demeanor and composure.

4) “Rei” is ongoing throughout training (not just ceremonial moments)

• “Rei” is described as present everywhere in training:
  • how you move in the dojo
  • avoiding passing between people
  • how to move around others (including moving behind someone rather than in front)
• It creates a persistent mindful state, not a checklist of gestures.

5) Sensitivity to disrespect (“yūdai/būdō” vs “tōdei” distinction)

• The instructor notes Japanese includes distinct terms for:
  • Active disrespect (being disrespectful)
  • Failure to follow etiquette properly
• Detecting disrespect is framed as important for safety, enabling faster situational assessment.

Methodology / practical instruction elements

A) How the instructor says to approach “Rei” training

• Approach “Rei” as personal conduct, but understand it expands to:
  • managing your own behavior within a group
  • managing your group’s response
  • managing how you affect another group/person
• Practice with continuous attention to details:
  • maintain a heightened state of attention from start to finish
  • treat dojo conduct as involving safety and readiness, not only appearance
• For foreigners in a Japanese dojo:
  • recognize that the cultural/language advantage is reduced
  • compensate by watching others closely
  • mirror what you observe so you can behave appropriately in the moment

B) Protocol examples used to explain the idea of correct conduct

• Bowings and ceremonial sequences
  • convey respect
  • also support practical needs like safety/security and readiness
• Handshake (Western example)
  • symbolizes presenting that you do not hold a weapon
• Military salute (origin/example)
  • historically connected to adjusting visibility (e.g., visor/helmet context)
  • also helps others identify you clearly

C) Dojo-entry/positioning logic tied to “Rei” and safety

• General guidance on dojo structure:
  • entrance on the back wall (shimoza / shimoza-side concept) to maximize distance from the front
  • “front” is where the portable shrine (kamiza) and senior figures are
  • senior-to-junior arrangement: front-to-back and positional ordering right-to-left
• Rules/rationale when entering/leaving based on dojo layout:
  • do not show your back to positions of importance (the front)
  • example: if the entrance is on a less-ideal wall, you may enter from one side and leave from the other to avoid “back to importance”
  • “hiding something” interpretation: showing your back can be read as concealment or something not visible
• Additional visibility rationale:
  • if touching/approaching the weapon side, ensure others can see it
  • maintain a state where weapon-related actions do not surprise others
