Tokyo (CNN Business) A robot that can find the laundry even if you've moved it could give Japan's startup scene a much-needed shot in the arm.

Preferred Networks co-founder Daisuke Okanohara says his company's artificial intelligence software enables the Human Support Robot to react to changes in its environment in unique ways.

Thetechnology is a source of pride for the Tokyo-based firm, which is worth roughly $2 billion, according to CB Insights. That kind of valuation is rare for a Japanese startup. While the United States and China have seen the rise of hundreds of unicorns — private tech companies worth at least $1 billion — Japan has just three.

Falling behind

It wasn't always this way. The third biggest economy globally was once a leader when it came to disruptive, innovative technology. After all, this was the country that gave the world pocket calculators, the Sony Walkman and LED lights. But Japan has since fallen far behind in the innovation race.

Pokemon was created by Satoshi Tajiri in 1995 and is one of the best-selling video game franchises of all time. It's a world in which humans catch and train fictional creatures, Pokémon, to battle each other. It grew to include trading card games, movies, comic books and toys. The spin-off animated TV show is perhaps the best-known example of Animé, a Japanese-style of animation. The newest incarnation of the franchise was "Pokemon Go," an augmented reality game for smartphones that took the world by storm in 2016.

Food in Japan can look too good to be true, and often it is. Japan is the fake food capital of the world. In the early 20th century a businessman, Takizo Iwasaki, supposedly saw candle drippings on a table and became inspired to create lifelike food out of wax. Iwasaki sold his waxwork food models to restaurants which used them to advertise their meals. Fake food is now made from plastic and can be seen all over Japan, and beyond.

While Ramen is known globally as a Japanese dish it actually has its origins in China, when Chinese tradesmen brought over the soup in the 19th century. It soon became a staple food of the working class. But it was in 1958 that the first packaged modern Ramen, or "instant noodles" reached supermarket shelves. The soupy dish isn't just a national delicacy, it's also a culture. There are Ramen celebrities, museums and video games.

Karaoke has become a globally popular way for people to embarrass themselves in front of friends, strangers and work colleagues -- but the Japanese were doing it before anyone else. The first karaoke machine was invented in Japan in 1971, by a drummer called Daisuke Inoue, who plugged a tape player into an amplifier. It came about after a businessman asked Inoue to record on tape his favorite songs so that he could sing to them.

Japan is a nation of inventors. But it hasn't just given us robots, laptops and reliable cars -- it also has a huge influence over popular culture. Here are just some of the Japanese inventions that have changed the way we live. The Oxford Dictionaries named "selfie" as word of the year in 2013, but the selfie stick has in fact been around much longer. The date and place of the first selfie stick is a contentious issue, but the first patented selfie stick, originally called the "extender stick," was created in Japan by Hiroshi Ueda and Yujiro Mima in the 1980s.

Japanese companies were known in the 1980s and 1990s for making consumer tech products lighter and thinner, said Kenji Nonaka, senior partner with McKinsey. But then the market changed. "Super engineered" products were less in demand. Consumer-driven tech, with an emphasis on software, became more important, according to Nonaka.

"To be successful for that innovation, you have to be close to the customer, you have to have a sense of those customers' needs. And Japan is very far from the United States and far, culturally, from China," he said.

Google GOOGL Netflix NFLX Facebook FB Amazon AMZN Moreover, startups likeand— all American — have been responsible for the most exciting innovations in tech over the last 20 years, he added.

"In Japan, there is a very limited startup community," Nonaka said. "Everyone wants to go to large enterprise[s]."

Experts also blame the innovation decline on Japan's homogenous work culture, combined with a risk-averse financing system that has stifled creativity and innovation.

Japan's government directs tech investment . The salary-man work culture discourages employees from leaving their jobs. And companies rely heavily on banks, rather than debt markets, to raise money.

The different approach to investment is particularly significant. Angel investors are plentiful in the United States and China, for example, where there's more of a willingness to bet on people and companies that are taking big risks and are likely to fail.

"When you're going for new product innovation, the money and personnel that can be attracted in a short amount of time is amazing in the United States," said Seijiro Takeshita, dean and professor at the University of Shizuoka's School of Management and Information. But Japan is home to "a culture that frowns on failure," he added. "At Japanese corporations, it's more important not to fail than to succeed."

Some signs of progress

Japan excels at taking an existing tech product and making significant improvements on it so that it can be more easily mass produced. Sony That's not to say Japan doesn't innovate at all. Takeshita said there are stilla lot of ideas in the country, but they just aren't as splashy as what's coming out of Silicon Valley or Shenzhen. Japan excels at taking an existing tech product and making significant improvements on it so that it can be more easily mass produced. Sony debuted the Walkman in 1979 , for example, but magnetic cassette technology had been around for more than a decade by then.

Japan is still a world leader in technological innovation based on another metric. It filed more intellectual property patents per capita than any other country in 2018, according to a report released last month by the World Intellectual Property Organization. (China and the United States still rank higher in total number of patents filed.)

"the political environment, education, infrastructure and business sophistication" needed to drive innovation, the group said. The country ranked 15th in the World Intellectual Property Organization's Even then, Japan has fallen far behind when it comes to"the political environment, education, infrastructure and business sophistication" needed to drive innovation, the group said. The country ranked 15th in the World Intellectual Property Organization's annual global innovation list earlier this year, falling two places. It lagged far behind countries such as the United States, the United Kingdom and Israel. Switzerland came first.

Daisuke Okanohara, co-founder of Japan's biggest tech unicorn Preferred Networks, says the country needs more creative diversity for new ideas to flourish.

Okanohara, the Preferred Networks co-founder, pointed to diversity as one solution. His company employs roughly 270 people, and about 10% are foreigners, representing more than 30 countries. The company recommends using English around the office and on Slack, and employs translators to help with communication. By comparison, foreign-born individuals make up roughly 57% of Silicon Valley's technology workforce, according to a 2017 report published by the Silicon Valley Leadership Group, an advocacy organization, and the Silicon Valley Community Foundation.

"We need more diversity to think or adapt more new, radical ideas," Okanohara said, adding that Preferred Networks wants to create an environment where "new ideas [can be] easily adopted and tried."

Nonaka, of McKinsey, said Japanese startups also need to have global ambitions.

"Many startups have been very comfortable with succeeding in Japan. Japan's not a small market, but it's small compared to the US and China. They need to think of their growth in the US and China when they start their business," he said.

"Compared to places like China there aren't many opportunities," he added.

Toyota. TM But his company did pique the interest of another big Japanese company:The carmaker first began working with Preferred Networks on joint research and development in 2014. Toyota has invested more than 11 billion yen ($101 million) in the startup since 2015, fueling work on projects such as artificial intelligence, robotics and driverless technology.

That kind of investment has enabled some important breakthroughs for the company — like its AI software. After all, the robot that Preferred Networks is powering with its technology was made by Toyota.
