Late Edo to Meiji Historical Reconstruction Project

Inspired by an extraordinary nineteenth-century aikuchi koshirae signed by the renowned metalworker Hagiya Katsuhira, this historical reconstruction combines meticulous research, digital reconstruction and traditional metalworking techniques to reinterpret one of the most dynamic masterpieces of Japanese sword furniture.

Project Overview

Inspired by an exceptional nineteenth-century aikuchi koshirae signed by the celebrated metalworker Hagiya Katsuhira (萩谷勝平), this project explores the dramatic sculptural language that characterised the highest achievements of late Edo and early Meiji Japanese sword fittings.

Unlike mountings that rely upon restrained ornamentation, this historical design transforms the entire koshirae into a continuous sculptural composition. A powerful rain dragon coils around the lacquered saya, accompanied by roaring tigers, swirling clouds and richly modelled decorative details that extend seamlessly across the mounting.

Rather than reproducing an antique object through direct duplication, this project represents an independently developed historical reconstruction created through careful research, digital modelling and traditional handcrafted techniques.

Historical Background

The original mounting is attributed to Hagiya Katsuhira (1804–1886), one of the most celebrated Japanese metalworkers of the late Edo and early Meiji periods.

Katsuhira studied under Ishiguro Masayoshi, an important master of the Ishiguro School (石黒派), and inherited many of the school's sophisticated metalworking techniques before developing his own highly recognisable artistic style.

His works are distinguished by dramatic high-relief carving, dynamic animal compositions, exceptional mixed-metal decoration and remarkable technical refinement. Today, his sword fittings are regarded among the finest achievements of nineteenth-century Japanese decorative metalwork.

The historical mounting that inspired this reconstruction represents this mature artistic period, combining sculptural energy with extraordinary craftsmanship.

Artistic Features

The defining artistic theme of this koshirae is the relationship between the Rain Dragon and the Tiger.

Throughout East Asian artistic tradition, the dragon represents the forces of heaven, rain and transformation, while the tiger symbolises strength, courage and earthly power. Together they create a dynamic visual dialogue between opposing yet complementary forces.

The lacquered saya is decorated with flowing clouds executed in black and gold togidashi maki-e, around which a boldly sculpted rain dragon winds dramatically across the surface. Rather than functioning as isolated decorative elements, the dragon becomes an integral part of the overall composition.

The accompanying kozuka depicts two prowling tigers, while the kashira presents two wrestling tigers enhanced by subtle contrasts in material and surface treatment, creating a rich sense of depth and movement.

The masterful integration of mixed-metal craftsmanship, high-relief carving and refined surface finishing exemplifies the extraordinary technical sophistication associated with Hagiya Katsuhira's work.

The Original Historical Mounting

The historical mounting was created for a hira-zukuri aikuchi tantō forged by Izumo no Kami Sadashige, a swordsmith active during the seventeenth century.

More than two centuries later, the blade was remounted in an elaborate aikuchi koshirae created by Hagiya Katsuhira during the late nineteenth century.

This remarkable combination reflects the long Japanese tradition of preserving treasured blades by commissioning entirely new mountings that reflected the artistic tastes of a later generation.

Reconstruction Philosophy

Every historical reconstruction begins with understanding rather than imitation.

Rather than attempting to produce an indistinguishable copy of a historical object, our objective is to study its artistic language, construction methods and sculptural composition before developing an independent reconstruction through contemporary craftsmanship.

Historical references are rarely complete. Consequently, each reconstruction requires careful interpretation supported by historical research, digital reconstruction and traditional handcraft.

Every finished work therefore represents a contemporary historical reconstruction rather than a literal duplicate of the original.

Reconstruction Process

Historical Research

Historical photographs, auction catalogues, museum references and published documentation were carefully examined to understand the original composition, dimensions and artistic characteristics.

Digital Reconstruction

Each individual component was independently reconstructed as a three-dimensional digital model using appropriate digital modelling and sculpting techniques. Particular attention was given to the dragon's flowing movement, the anatomical structure of the tigers and the interaction between sculptural forms and the lacquered saya.

Traditional Metalworking

The reconstructed components were produced using traditional lost-wax investment casting before undergoing extensive hand chasing, engraving, carving, filing and polishing to refine every sculptural detail.

Surface Finishing

Traditional finishing techniques were applied to recreate the visual richness of nineteenth-century Japanese metalwork while preserving the identity of the work as a contemporary historical reconstruction.

Project Specifications

Historical Significance

This remarkable koshirae represents one of the highest expressions of Japanese sword furniture during the nineteenth century.

Its extraordinary combination of sculptural dragon imagery, expressive tiger compositions, refined lacquer techniques and sophisticated mixed-metal craftsmanship illustrates the remarkable artistic freedom achieved by Japanese metalworkers during the closing decades of the samurai era.

Project Disclaimer

It is inspired by publicly documented historical references and is intended to preserve traditional craftsmanship through contemporary reconstruction.

Unless explicitly stated, this work is not an official museum reproduction, licensed replica or product affiliated with any museum, institution, artist, estate or rights holder.

As with all handcrafted historical reconstructions, slight variations in carving, dimensions, surface texture and finishing are an inherent characteristic of traditional craftsmanship.
