Around 1831, print shops in Edo — modern Tokyo — began selling a new landscape sheet for roughly the price of a double helping of soba noodles. It showed an enormous wave rearing over three open boats, its crest breaking into claw-like fingers of foam, while far off in the trough, reduced to a snow-capped wavelet, sat Mount Fuji. Under the Wave off Kanagawa — universally known as the Great Wave — was cheap, popular and printed by the thousand. Nearly two centuries later it is plausibly the most recognised, most reproduced work of art on the planet: on museum walls, phone cases, a national banknote and the wave emoji in your pocket.
Its creator was a man in his early seventies who had already lived several artistic lives. Katsushika Hokusai — one of some thirty names he adopted and discarded over a career that began in his teens — signed the print as "Iitsu, formerly Hokusai", and was by then a legend of restless eccentricity: he is said to have moved house around 93 times, and called himself Gakyō Rōjin, "the old man mad about painting". Nor was the Wave the serene product of a comfortable old age. Hokusai had recently weathered a stroke, the death of his wife and crushing debts, some run up by a wayward grandson; the Thirty-Six Views of Mount Fuji series, of which the Wave is the most famous sheet, was among other things a septuagenarian's scramble for income. The series proved so popular that its publisher, Nishimuraya Yohachi, extended it to 46 prints, the "thirty-six" of the title notwithstanding. Hokusai was already beloved for his Manga — fifteen volumes of teeming sketchbooks of people, animals and demons — and in his final years he worked alongside his daughter Ōi, a formidable painter in her own right whom connoisseurs have been rediscovering ever since.
Blue from abroad, perspective from abroad
The Wave's drama owes much to a novel ingredient: Prussian blue, the synthetic European pigment known in Japan as bero-ai — "Berlin indigo" — which had recently become cheaply available through Dutch and Chinese traders. Unlike Japan's fugitive vegetable blues, it was deep, stable and vivid, and the early prints of the Fuji series were marketed partly on the sensational new colour. The composition, too, is a hybrid: Hokusai had studied the Western single-point perspective that filtered in through Dutch engravings at Nagasaki, Japan's one open port, and the Wave's low horizon and receding depth are as much European as Japanese. The scene itself is frequently misread: this is not a tsunami but a monstrous open-sea breaker, and the three vessels beneath it are oshiokuri-bune, fast boats hurrying fresh fish to the Edo markets, their oarsmen flattened in dread or determination.
As a woodblock print, the Wave was never a single object. Impressions were pulled until the cherry-wood blocks wore soft — plausibly several thousand in the first campaigns — and of these perhaps a few hundred survive, their condition and early printing determining values that have climbed into the millions at auction. The trap for quizzers is the plural: museums from the British Museum to the Met each own a Great Wave, and none of them owns the Great Wave, because no unique original exists. Scientists have joined the admirers, noting how accurately the crest's self-similar, fractal-like fingers capture the physics of a breaking wave that no camera of the age could freeze.
The wave goes west
When Japan was forced open in the 1850s, its prints flooded into Europe as exotic ephemera — famously turning up as packing paper — and helped ignite the craze called Japonisme. Monet amassed Japanese prints at Giverny; Van Gogh, a devotee, marvelled in a letter at the Wave's terrifying grip; Debussy kept an image of it as he composed La Mer, and the 1905 first edition of the score carried a redrawn Great Wave on its cover. The image has since become Japan's visual ambassador: in 2024 it was engraved on the new 1,000-yen banknote. Hokusai worked almost to his death in 1849, aged 88, reportedly lamenting that with just five or ten more years he might finally have become a true painter. The old man mad about painting need not have worried: his cheap blue sea-print has outlasted empires, and its wave has still not broken.
Quiz nuggets
- Under the Wave off Kanagawa (c. 1830–31) is the most famous sheet of Hokusai's Thirty-Six Views of Mount Fuji, a series extended to 46 prints.
- Hokusai was in his early seventies and used the newly affordable imported pigment Prussian blue (bero-ai).
- The wave is an open-sea breaker, not a tsunami; the boats are oshiokuri-bune fish-delivery boats.
- Thousands of impressions were printed and no unique original exists; surviving early impressions fetch millions.
- Debussy's La Mer (1905) carried the Wave on its first-edition cover, and Japan put it on the 1,000-yen note in 2024.
