INTRODUCTION
The Strength of the House series is a novel.
It is a works of fiction developed with access to materials held by the Iwamoto Archive and prepared with the assistance of the Iwamoto Archival Process Group. These materials include internal documents, correspondence and working papers created by members of the Iwamoto house across multiple generations.
The author was granted full and unrestricted access to these materials for the purposes of research. The Iwamoto Corporation did not exercise editorial control over the narrative, nor did it seek to influence the interpretation, structure or conclusions drawn within this work.
While the story is fictional, it is informed by archival sources that reflect how the Iwamoto house understood itself, its responsibilities and its continuity across periods of profound social, political and economic change. Where interpretation has been required, it has been undertaken by the author.
This publication represents the first occasion on which elements of what has come to be known internally as Iwamoto ki have been shared beyond the house. After due consideration, the Corporation determined that the time and context made this disclosure acceptable.
That determination should not be read as a change in policy. At the time of publication, no further access to the Iwamoto Archive is contemplated. Iwamoto ki endures not because its records are known, but because they are lived.

EDITORIAL ADDENDUM NOTE
The included addendum materials are drawn from a contemporary internal archival programme established during the preparation of this volume.
In 2024, Iwamoto Corporation initiated a formal review and digitisation of surviving internal papers held across private holdings, subsidiary records and legacy corporate archives. The programme was commissioned to support public-facing historical clarity, institutional continuity and long-term records preservation.
The work is administered by the Public Affairs and Media Division and conducted under the direct authority of Ema Iwamoto, Chief Executive Officer, Public Affairs and Media. The archival programme operates as a discrete internal unit and reports directly to her office.
AUTHOR'S NOTE
I would like to thank Ema Iwamoto, the Iwamoto Corporation and the members of the Iwamoto Archival Process Team for the access and trust extended during the research and preparation of this work.
The materials held by the Iwamoto Archive are extensive and exacting. They were made available without restriction or condition. No editorial guidance was offered, nor was any sought. Responsibility for interpretation, selection and narrative construction rested entirely with me.
The addenda included on this site were prepared by the Archival Process Team as contextual reference. They are not part of the narrative itself.
Readers wishing to better understand the structures, assumptions and continuity that inform the story may find it useful to read them before beginning the novel. The addenda reproduced here were selected by me and represent only a small fraction of the material consulted.
Over time, the story ceased to feel assembled and began to assert itself. Its characters became recognised rather than invented. It objected when I strayed and pressed forward when restrained. My role gradually shifted from author to custodian.
With all this said, the story that follows is a work of fiction. Any errors of judgement or emphasis are my own.
