In 1906, Japan sent more earthquake relief to a burning San Francisco than any other nation on earth: $244,960.10 — over half of all the foreign aid the city received, more than the next two largest donor nations combined.

In 1923, when an earthquake devastated Tokyo, America repaid the debt in full: one of the largest disaster relief efforts in its history.

A year later, Congress passed a law that closed America's door to Japanese immigration for good.

In 1941, whatever remained of the friendship between the two nations ended at Pearl Harbor.

Between those dates lies a century most people think they already know — and almost entirely don't.

A Japanese immigrant taught jujitsu to a sitting American president, inside the White House itself. Japanese farmers built the flower markets of California. American diplomats admired Japan as a rising civilization — even as American law declared its people unfit for citizenship.

An Uncertain Friendship is the story of how two nations that had genuine reason to like each other ended up at war — told through the immigrants, the diplomats, and the ordinary acts of memory, gratitude, and forgetting that neither side has fully reckoned with, even now.

On the surface, it looks like a simple story: a debt repaid in full, and a year later, a door shut for good. In reality, it was never that simple — this is not a story where one side was right, and the century from Perry's arrival to Pearl Harbor is the reason why.

“Grave reflections. Ominous of change. Undoubted beginning of end. Query — if for real good of Japan?”
— Townsend Harris, first American consul general to Japan, journal entry for September 4, 1856, written the evening he raised the first American flag ever seen in the empire, over the temple of Gyokusen-ji in Shimoda

About the Book

In the century before Pearl Harbor, the relationship between the United States and Japan was never one thing. It was diplomacy conducted by statesmen who genuinely admired one another. It was Japanese immigrants who built irrigation systems in California and revolutionized West Coast fishing. It was Japanese aesthetics and martial arts reshaping American art, architecture, and the temperament of a sitting president.

And running alongside all of it was a campaign, concentrated on the American West Coast but never confined to it, to exclude Japanese immigrants from American life by force of law. This book argues that campaign — not any single treaty or battle — was the central fact that determined how the other three relationships would ultimately fail.

“Understanding the relationship between America and Japan is also a way of understanding America itself — and understanding America is one of the clearest vantage points from which to see the rest of the world.”

From the Introduction

It is a remarkable sentence for the man who did the deed to have written. Harris was not a bystander lamenting a change forced on Japan by someone else; he was the American official who had just forced it himself, and he knew it. Even at that moment of American triumph — three years after Commodore Perry's warships had first appeared in Edo Bay, and with the treaty system that would define the relationship for the next half-century now underway — the man responsible could not escape the question of whether what he was doing was actually good for the country on the receiving end of it.

That question — whether the encounter between the United States and Japan was, on balance, a good thing, for whom, and at what cost — runs through the entire century that followed, and it is the question this book tries to answer with more care than it usually receives. What followed Harris's flag-raising is, on its surface, a familiar story: an isolated nation forced open by superior force, a rapid and remarkable modernization, a rise to great-power status, a slide into rivalry, and finally, catastrophic war. It is a story most readers, American and Japanese alike, believe they already know.

They do not know it, or at least not all of it. This book is an attempt to fill in what has been left out.

About the Author

John Suzuki

John Suzuki is a writer and independent researcher whose life and work have moved mainly between the United States and Japan. His interest in the history of U.S.–Japan relations grew out of his own family background: his father was born in Kumamoto Prefecture, a region that sent many of its people to Hawai'i during the emigration wave of the late nineteenth and early twentieth centuries, and he has relatives who are, generations later, American citizens because of choices made in that era.

Suzuki has spent much of his career working at the intersection of finance and international affairs, an experience that shaped his interest in how nations misjudge and misremember one another over time. An Uncertain Friendship is his first book — an attempt to place his own family's history within the fuller, often uncomfortable context of the century that preceded the Pacific War.

He is currently at work on further studies of American history, structure, and character, approached from other angles than the one this book takes.
