What does 'no holes' on the nakago mean for builders?
Updated Mar 2026
A nakago listed as 'no holes' or 'no mekugi-ana' means the tang has been left undrilled at the factory. For custom koshirae builders, this is often preferable because the mekugi-ana (the hole through which the bamboo mekugi peg secures the handle) can be drilled to match the exact position of a hand-fitted tsuka rather than relying on a pre-set factory location. Proper mekugi placement depends on the interior geometry of your specific tsuka core, so starting with an undrilled nakago gives you full control over the fit. This is standard practice in traditional Japanese sword mounting (shirasaya and koshirae fitting) and is considered the correct approach when assembling a display-grade build from individually sourced components.
