CLOSE-UP: Kotaro Horiuchi

A life spent in uncharted waters of boat design

As a boy, Kotaro Horiuchi was obsessed with planes, but he moved on to create and pilot with a passion all manner of waterborne vessels

Considering the current state of Japan's economy, it's remarkable to recall that 60 years ago there were hundreds of companies both old and new jockeying restlessly to fill the vacuum left after almost all the nation's cities were heavily bombed in World War II — jockeying, that is, with the kind of entrepreneurial verve now associated with China or India.

And yet, in the memories of many now elderly Japanese that bygone spirit of experimentation, creative product development and aggressive marketing lives on. Kotaro Horiuchi is a case in point.

Horiuchi, who is currently in his 85th year, is a boat designer whose career almost perfectly coincided with the postwar decades in which Japan rose from ruin to become the first country dubbed an "Asian tiger."

In 1950, Horiuchi joined a boat-making company called Yokohama Yacht, where he was soon designing vessels for clients as varied as local ferry operators and the U.S. Navy. Later, he moved to Yamaha Corp., then still known as Nippon Gakki Company (Japan Musical Instrument Manufacturing Company), which was at the time just starting to expand from being an instrument manufacturer into producing sporting goods, motorbikes, outboard engines and motorboats.

At Yamaha, Horiuchi designed or led design teams working on dozens of marine craft. With some products, such as private pleasure cruisers, the company created not only boats but also new markets, as its boats attracted more and more people to leisure possibilities afloat.

With other products, such as professional fishing vessels, Horiuchi and his colleagues didn't create a market, but instead revolutionized the existing one by introducing new, super-strong but lightweight materials such as fiber-reinforced plastic.

But not all Horiuchi's creations became hit products. His fascination for hydrofoils, for example, has always been one step ahead of that of the marketplace, where buyers both private and commercial have been slow to see the appeal of these boats with "wings" (foils) attached to the end of struts protruding into the water from the hull. As they move through the water, the foils generate lift just as airplane wings do, so the boat rises up above the water as its speed is increased.

"If the hull isn't touching the water, then resistance is reduced, speed is increased and fuel efficiency also increases," Horiuchi enthuses.

Since making his first hydrofoil in 1952, copying a design from a U.S. magazine, Horiuchi has made dozens of experimental versions, from single-rider motorbike-style ones to sail- and even pedal-powered boats.

Horiuchi's other passion is rowing. Just last year he won the men's over-80 single-scull division at the World Rowing Masters Regatta in Ontario, Canada, beating competitors from Brazil, the United States and elsewhere. That passion he inherited from his father, who was a physics professor at Hokkaido University and the well-to-do son of a construction company magnate. "He drummed into me a love of rowing from an early age," Horiuchi reminisces.

Horiuchi had three children of his own. One passed away two years ago, and another now lives with her family in a house adjacent his in the seaside suburb of Kamakura, Kanagawa Prefecture. His own wife passed away three years ago.

The Japan Times recently spent a morning with Horiuchi at his home. Flicking through dozens of photographs, boat sketches and plans, he enthusiastically recalled a career spent both literally and figuratively riding the crest of Japan's wave of postwar economic development. Horiuchi was also keen to offer some thoughts on the performance of Japan's current corporate leaders — but only after explaining the merits of yet another new-style boat he continues to work on to this day.

Your career was spent designing boats, but when did you first take to the water yourself?

That would have been around 1935, when I was 9. My father had just returned from four years of research in Europe, where he had acquired a German faltboot, which was a foldable kayak.

Then he became a professor at Hokkaido University and so the whole family moved from Tokyo to Sapporo, where there were lots of lakes suitable for rowing. He used to take us out every Sunday.

Did you enjoy it?

No, I hated it. The faltboot had its own little trolley and you had to pull it apart and put it on the trolley and then squeeze it on a packed bus, take it off, take it to the lake and then reassemble it — and it weighed around 70 kg.

He also taught me how to row sculls (light, narrow rowboats for racing). Gradually I came to like it. Or at least, I became brainwashed to think I liked it!

Was rowing popular in Japan back then?

It had been when my father was a student, in the 1920s. There weren't really any other sports you could do, and baseball didn't become popular until the '30s.

Did you think at that time that you'd end up designing boats?

Not at all. As a child I was mad about planes. I spent so much time making planes with the boy next door that my father had to ban them in the house.

What kind of planes?

We made gliders and rubber-band planes. In Sapporo there were lots of great places for flying gliders. If you used a rubber band you could get them up hundreds of meters in the air, and they would just keep on going forever.

Why didn't you become a plane designer?

I wanted to do that, but when I went to Tokyo Imperial University (today's University of Tokyo), the war had just ended and the construction of planes was prohibited (under the terms of the Allied Occupation). So there was no aeronautical engineering department, but the professors were still there, of course — in the department of applied mathematics. So that's where I went.

Were you at school during the war?

After I graduated from junior high school I went to the Second Higher School, in Sendai, Miyagi Prefecture. ("Higher school" was for older students than today's high schools, and included what are now the first two years of university. There were only eight of these exclusive institutions in Japan, with the "First Higher School" being in Tokyo.)

I spent three years there and, in my second year, the war ended. Then I went to university.

I graduated in 1950 and ended up at Yokohama Yacht (absorbed into JFE Engineering Corp. in 2002), which had made torpedo boats during the war and was then making passenger ferries, Coast Guard patrol boats and the like. It was run by one of my seniors at a rowing club, Shiro Chiba.

What did you do there?

Well, the first thing he got me doing was to build a new "knuckle four," a deep-hulled rowing boat crewed by four rowers and a cox.

Was that part of your work?

No, I had to do it after hours.


Except without pay! I just did what he said. I got a carpenter to help me a bit at the end, but we made a nice boat.

Then he said he wanted me to enter the Kokutai (National Sports Festival) with that boat. I rounded up the well-built guys at the company to crew it with me and we started training every morning.

Where was this?

The company was at the mouth of the Tsurumi River, in Kanagawa Prefecture.

We practiced for about a month and a half, and then went to the festival, which was in Nagoya that year. And we won!

At that time, during work hours, I presume you were working on other boats. I believe you even made a spy boat.

Yes, we received an order for a spy boat from the U.S. military. The Korean War (1950-53) had started, and they needed a fast boat that looked like a regular Chinese fishing junk.

How do you make a speedboat out of a junk?
