Yes. The blade steel extends through the entire length of the handle as a full-tang build, which means the tsuka is mounted over a solid steel core rather than being glued to a short rat-tail extension. This construction method gives the replica a balanced weight distribution and a solid, unified feel when you pick it up. For display purposes, full-tang assembly also ensures long-term structural stability — the handle will not loosen or wobble over time the way friction-fit or adhesive-only builds tend to degrade. The tang is secured through the handle with a mekugi pin, following the same assembly principle used in traditional Japanese sword making.
