Goshin‑Ryū Technical Black Belt Ranks

Shodan (1st Dan)

Belt: Black belt with gold characters Meaning: The beginning of true study; foundational black belt rank.

One‑Year Maturity Period All new Shodan enter a mandatory one‑year maturity period between the successful completion of the test and the formal awarding of the rank. During this period:

• The student wears a plain black belt with no characters
• The Shodan certificate is held until the maturity period is complete
• Training continues naturally, with ongoing development in skill, character, and responsibility
• At the instructor’s discretion, the student may begin exposure to Nidan‑level material
• Formal Shodan rank is awarded at the completion of this maturity period.

Nidan (2nd Dan)

Belt: Black belt with gold characters Meaning: Consolidation of skill; deeper understanding of foundational principles.

Sandan (3rd Dan)

Belt: Black belt with gold characters Meaning: Advanced technical proficiency; beginning of senior‑level comprehension.

Yondan (4th Dan)

Belt: Black belt with gold characters Meaning: Senior black belt; technical maturity and leadership readiness.

Godan (5th Dan)

Belt: Black belt with red characters Meaning: Transition into high‑level seniority; red characters signify advanced authority and responsibility.

Rokudan (6th Dan)

Belt: Black belt with red characters Meaning: High senior rank; deep technical and philosophical understanding.

Nanadan (7th Dan)

Belt: Black belt with red characters Meaning: Senior master level; significant responsibility in transmission and preservation.

Hachidan (8th Dan)

Kudan (9th Dan)

Belt: Black belt with red characters Meaning: Highest technical rank recognized in Goshin‑Ryū; represents lifetime dedication, mastery, and stewardship of the system.

Note on Rank Structure

Out of respect for legitimate Sōke and 10th Dan practitioners in other martial traditions, Goshin‑Ryū does not use or award the rank of Judan. Within this system, the technical rank structure intentionally ends at Nanadan (7th Dan), with only one designated Hachidan (8th Dan) and one Kudan (9th Dan) serving as the senior leadership ranks.
