Sword Types

NBTHK Certification Grades

Each sword on NihontoWatch links back to its dealer for direct inquiry and purchase. Listings are aggregated daily from the dealers' own catalogs, and every entry includes the original source URL so collectors can verify provenance independently. The most commonly traded sword types are katana (the long curved sword worn edge-up, the classical samurai blade), wakizashi (the shorter companion sword), and tanto (daggers). Older styles include tachi (the ancestral long sword worn edge-down by mounted warriors), naginata (polearms with curved blades), and yari (straight spear blades) — these are rarer and command premium prices for surviving examples in koto-era (pre-1596) condition. The NBTHK (Society for Preservation of Japanese Art Swords) issues four primary certifications. Hozon ("worthy of preservation") confirms authenticity and quality. Tokubetsu Hozon ("especially worthy") marks a higher tier of preservation and importance. Juyo Token ("important sword") is the highest regularly awarded grade — typically the top 5% of items submitted. Tokubetsu Juyo Token ("especially important") is reserved for masterworks of national-treasure caliber, awarded only occasionally and after Juyo certification.
