Late Edo Period Historical Reconstruction Project.

Inspired by an exceptional late Edo-period aikuchi koshirae attributed to the Ishiguro School, this reconstruction combines historical research, digital reconstruction and traditional Japanese metalworking to preserve one of the finest expressions of nineteenth-century sword furniture.

Project Overview

Inspired by an exceptional late Edo-period aikuchi koshirae attributed to the renowned Ishiguro School, this project celebrates one of the highest achievements of nineteenth-century Japanese decorative metalwork.

The original work is distinguished by magnificent solid silver fittings, refined mixed-metal ornamentation and an extraordinary gold lacquer saya decorated with vibrant peacock feather motifs. Elegant three-dimensional peacock sculptures flow naturally across the mounting, creating a harmonious composition that reflects the remarkable artistic vision of late Edo craftsmen.

Rather than mechanically copying an antique object, this project represents an independent historical reconstruction created through careful research, digital reconstruction and traditional handcrafted techniques.

Historical Background

During the late Edo period, Japanese sword mountings evolved far beyond functional military equipment and became highly sophisticated works of decorative art.

Among the most influential schools of this period was the Ishiguro School (石黒派), founded by Ishiguro Masatsune I (1760–1828). Having studied under the Yokoya tradition, Masatsune established a distinctive artistic style characterised by expressive high-relief carving, elegant natural subjects, refined mixed-metal decoration and exceptional surface finishing.

The historical mounting that inspired this reconstruction is attributed to the Ishiguro School and is believed to have been created around 1840–1850, representing the mature artistic achievements of late Edo-period Japanese metalwork.

Artistic Features

The central artistic theme of this koshirae is Kujaku Myōō (孔雀明王).

In Japanese Buddhist tradition, Kujaku Myōō—known in Sanskrit as Mahāmāyūrī—is the Peacock Wisdom King, revered as a guardian who dispels evil, prevents calamity and protects against misfortune.

Rather than depicting peacocks merely as decorative birds, the original artist transformed them into a symbolic religious composition. Gracefully sculpted peacocks extend across the mounting, while the gold lacquer saya is richly decorated with multicoloured peacock feather motifs, creating an exceptional dialogue between lacquer craftsmanship and metal sculpture.

The extensive use of solid silver together with carefully composed mixed-metal decoration reflects the extraordinary level of craftsmanship associated with the Ishiguro School.

The Original Historical Mounting

The historical mounting that inspired this reconstruction was originally assembled with a signed blade by Fujiwara Sukesada, a swordsmith active during the Kanbun era (1661–1672).

Nearly two centuries later, the blade was remounted in an elaborate late Edo-period aikuchi koshirae attributed to the Ishiguro School. The resulting combination brought together an earlier Shintō blade with an exceptionally refined nineteenth-century mounting, illustrating the long Japanese tradition of preserving treasured swords through successive generations of craftsmanship.

This reconstruction focuses on faithfully interpreting the artistic character of that remarkable koshirae through historical research and traditional craftsmanship.

Reconstruction Philosophy

Every historical reconstruction begins with research rather than reproduction.

Our objective is not to create an indistinguishable copy of a historical object, but to respectfully study, interpret and reconstruct its artistic language through digital technology and traditional handcrafted techniques.

Historical references are often incomplete, making informed interpretation an essential part of every reconstruction. Each finished work therefore represents an independent contemporary reconstruction inspired by history rather than an exact replica.

Reconstruction Process

Historical Research

Historical photographs, published references and available documentation were carefully examined to understand the original composition, construction and artistic characteristics.

Digital Reconstruction

Each individual component was recreated through CAD modelling and digital sculpting, allowing proportions, relief depth and assembly relationships to be accurately studied before production.

Traditional Metalworking

The reconstructed components were produced using traditional lost-wax investment casting before being individually refined through hand chasing, engraving, carving, filing and polishing.

Surface Finishing

Traditional finishing techniques were applied to recreate the visual richness of late Edo decorative metalwork while preserving the identity of the work as a contemporary historical reconstruction.

Historical Significance

The original koshirae exemplifies the remarkable artistic development of Japanese sword furniture during the nineteenth century.

Its harmonious combination of sculptural metalwork, luxurious lacquer decoration and Buddhist symbolism demonstrates how sword mountings had become objects of artistic expression as much as functional components of the sword.

This project represents an opportunity not only to preserve an exceptional historical design but also to celebrate the craftsmanship and cultural heritage of one of Japan's most influential metalworking traditions.

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 or rights holder.

As with all handcrafted historical reconstructions, minor variations in carving, dimensions, surface texture and finishing are a natural result of traditional craftsmanship.
