When Tokuso Hamai saw a colorized version of a black-and-white photo of a picnic under blossoming cherry trees before World War II, memories of family members, most of whom died in the atomic bombing of Hiroshima in 1945, came pouring out.
“In colorized photos, people come to life,” said Hamai, now 86. “I often played near [the picnic site] and sometimes I would do some naughty things and get scolded by my father.”
The power of a colorized photo to reignite lost memories was eye-opening for Anju Niwata, a student who gave Hamai the colorized photo as a present three years ago.

The 75th anniversary of the end of World War II is today, and Niwata, now 18, said she hopes it would bring attention to her project with a Tokyo University professor to painstakingly colorize photos using artificial intelligence and their own research to spark lost memories for the rapidly aging generation who experienced the war.
“Seeing Niwata share the colorized pictures with Hamai, and then watching him recall his old memories one after another, made it feel like the ice around his frozen memories was melting away,” said Hidenori Watanave, the professor who taught Niwata how to colorize monochrome pictures using AI.
Niwata and Watanave call their colorization project “Rebooting Memories,” and they published a book last month of the colorized versions of about 350 monochrome photographs that were taken before, during and after the war.
Watanave and Niwata use three different types of AI photo coloring software. The AI is useful in identifying the accurate colors of natural things, such as the sea, the sky and human skin, but it cannot accurately colorize human-made objects like roofs and clothes, Watanave said.
So Niwata and Watanave painstakingly finish the AI-colorized photos by hand to get more accurate colors based on the photo owners’ memories and advice from experts.
They also look through historical documents and archives that show what the colors should look like.
Some photos take a few months to finish.
For Watanave, Twitter has become a powerful platform to pursue the colorization project.
When he posted a picture of the Hiroshima atomic bomb mushroom cloud that the AI software had colorized as white, a film director suggested that it should be more orange.
Watanave checked the testimonies of those who saw the mushroom cloud and also researched the components of the atomic bomb to see if it could actually make an orangish color. After confirming that it could, he added orange to the picture.
While the accuracy of the color is important, Niwata and Watanave said that the most vital thing is that the colorized photos match the memories of their owners.
However, time is running out: The average age of the atomic bomb survivors is about 83.
Niwata said that publishing the colorization book during the COVID-19 pandemic has made her think about analogies to the war.
“Our everyday lives have been stolen away by the coronavirus in a flash, which I think resembles what happened in the war. That’s why I feel like now is an opportunity for people to imagine [wartime life] as their own experience,” she said.
Watanave said that using new technology would hopefully help younger Japanese feel more of an attachment to those who lived through the war.
“People are forgetting wartime memories. We need to revitalize those old memories by using the latest method of expression and delivering it to the hearts of many people,” he said. “By the time we mark the 80th or 85th anniversary, we need to come up with a new way of expressing” wartime memories.
ECONOMIC WORRIES: The ruling PAP faces voters amid concerns that the city-state faces the possibility of a recession and job losses amid Washington’s tariffs Singapore yesterday finalized contestants for its general election on Saturday next week, with the ruling People’s Action Party (PAP) fielding 32 new candidates in the biggest refresh of the party that has ruled the city-state since independence in 1965. The move follows a pledge by Singaporean Prime Minister Lawrence Wong (黃循財), who took office last year and assumed the PAP leadership, to “bring in new blood, new ideas and new energy” to steer the country of 6 million people.

Archeologists in Peru on Thursday said they found the 5,000-year-old remains of a noblewoman at the sacred city of Caral, revealing the important role played by women in the oldest center of civilization in the Americas. “What has been discovered corresponds to a woman who apparently had elevated status, an elite woman,” archeologist David Palomino said. The mummy was found in Aspero, a sacred site within the city of Caral that was a garbage dump for more than 30 years until becoming an archeological site in the 1990s. Palomino said the carefully preserved remains, dating to 3,000BC, contained skin, part of the
Russian hackers last year targeted a Dutch public facility in the first such an attack on the lowlands country’s infrastructure, its military intelligence services said on Monday. The Netherlands remained an “interesting target country” for Moscow due to its ongoing support for Ukraine, its Hague-based international organizations, high-tech industries and harbors such as Rotterdam, the Dutch Military Intelligence and Security Service (MIVD) said in its yearly report. Last year, the MIVD “saw a Russian hacker group carry out a cyberattack against the digital control system of a public facility in the Netherlands,” MIVD Director Vice Admiral Peter Reesink said in the 52-page
‘WATER WARFARE’: A Pakistani official called India’s suspension of a 65-year-old treaty on the sharing of waters from the Indus River ‘a cowardly, illegal move’ Pakistan yesterday canceled visas for Indian nationals, closed its airspace for all Indian-owned or operated airlines, and suspended all trade with India, including to and from any third country. The retaliatory measures follow India’s decision to suspend visas for Pakistani nationals in the aftermath of a deadly attack by shooters in Kashmir that killed 26 people, mostly tourists. The rare attack on civilians shocked and outraged India and prompted calls for action against their country’s archenemy, Pakistan. New Delhi did not publicly produce evidence connecting the attack to its neighbor, but said it had “cross-border” links to Pakistan. Pakistan denied any connection to
