Today they have evolved, and continue to inspire garden design at a time when many people are trying to forge a closer connection between indoor and outdoor spaces.

“One reason that gardens are so successful in Japan is that the house-garden relationship is set up to be so integrated. There are large views of the garden, and more unobstructed views. Gardens are enclosed and surround the house, so it’s as if your living space extends out much further,” says Asher Browne of Oakland, New Jersey, who trained in Kyoto, Japan, and now creates Japanese-inspired gardens for clients in the U.S.

“That aesthetic is definitely catching on.”

Japanese garden design in this country has moved well beyond stereotypical features like lanterns and imported Japanese cherries and maples, says Sadafumi Uchiyama, chief curator of the Portland, Oregon, Japanese Garden and director of the International Japanese Garden Training Center there. Uchiyama is a third-generation Japanese gardener from southern Japan.

The surrounding planting is manipulated to provide enclosure in a "distilled" style that celebrates the natural landscape of Minnesota, particularly the north shore of Lake Superior and the spectacular Boundary Waters.

At first, he says, Japanese gardens in the U.S. “copied the stone lanterns, water basins and stepping stones. But gradually, they started to design more original and authentic gardens. We are now getting a much closer look at quality,” with more widely available books and expertise.

There are over 200 Japanese-style public gardens in the U.S., according to the North American Japanese Garden Association, which features a North American Japanese Garden Finder on its website. Leading ones include the Portland Japanese Garden; the Shofuso Japanese House and Garden in Philadelphia; the Anderson Japanese Gardens in Rockford, Illinois; and the Japanese Friendship Garden in San Diego.

Browne says that in the Japanese aesthetic, garden spaces are linked with interior spaces so that each view from a home is a perfectly composed, almost painterly, view of the garden around it.

“In Japan at least, it seems that there is one core idea that has come down over centuries, and that is the idea of bringing the beauty of nature into daily lives,” he says.

Other aesthetic concepts he says are widely appreciated now are asymmetrical balance, and the beauty and importance of rocks, stones and boulders as the “bones” of a composition, which can then be filled in in a supportive way with plantings.

John Powell, a garden builder and pruning specialist from Weatherford, Texas, who trained in Japan, says he was attracted to Japanese gardens by “the seamless connection between interior and exterior space, which is evocative of the larger natural world, sometimes in a very compressed space.”

“That is a big change from the U.S., where the landscaping was traditionally there to dress the exterior of the house, but was very disconnected from interior space. I think especially today, that idea of connecting the indoors and the outdoors is an aesthetic that a lot of people strive for,” he explains.

The Japanese garden aesthetic “is very simple sounding, but it’s the most difficult thing I ever thought of in my life,” explains Powell.

As for sustainability, there’s been a major shift in thinking about Japanese-style gardens away from specimen gardens, which tend to feel a bit like a botanical garden, and toward greater use of plants adapted to local environments.

“It’s very possible to create a wonderful Japanese garden using all native plants,” says Browne.
