Japan is famous for its travel and dining.
While the country is known for its beaches, it is also home to the world’s largest population of backpackers.
But it also has some of the worst air pollution in the world, with the country ranking second worst in terms of PM10 levels, the amount of toxic particles found in the air.
Read more about air pollution: Japan has strict rules that limit the amount and type of cars people can bring in and out of the country.
There are also restrictions on what type of food they can eat and the number of people they can bring with them.
But as a rule of thumb, most people will be fine with just one or two people on a trip, according to the Japanese Tourism Agency (JTA).
This has led to some of Japan’s best-known attractions, like Kyoto, taking on a new look and new people, such as a few hundred backpackers on their way to Tokyo.
“We think the new Tokyo skyline is a real landmark for the Japanese people,” said Akiko Yamaguchi, director of the Japan tourism agency, in an interview with Al Jazeera.
“It’s one of the reasons why Japan has become so popular in the last couple of years.”
