Before traveling to Japan, it’s crucial to familiarize yourself with the many customs and traditions the people follow. For example, taking your shoes off is customary before entering a home, temple, shrine, traditional inn, and even certain schools.

Removing your shoes signifies respect and is deeply integrated into Japanese culture. 

3. Japan is famous for its bullet trains or Shinkansen

Among the many interesting facts about Japan are its bullet trains, or Shinkansen, which represent the country’s technological advancement in travel. The trains run at up to 200 mph and achieve these high speeds through electric propulsion, a sleek aerodynamic design, and magnetic levitation. 

The arrival of the bullet trains and the country’s hosting of the Tokyo Olympics in 1964 signaled the beginning of a more modern Japan after the country’s defeat in World War II.

4. It’s polite to slurp your noodles and eat noisily in Japan

While eating noisily in public can be considered rude in Western countries, in Japan, it’s considered polite to make noise while you eat certain foods!

However, this only goes as far as eating Japanese noodles, like soba, udon, ramen, and somen, and drinking tea. So don’t feel you have to slurp over your sushi! 

Considering the various cultural norms in Japan, it’s important to rehearse what to do and what not to do before you travel. 

5. Japan has over 100 castles

One of the best things to do in Japan is to visit its most famous castle, Himeji Castle, a national treasure and UNESCO World Heritage Site.

6. Bowing is essential in Japan — even the deer do it

In Japan, bowing, or ojigi, is a form of greeting, showing respect, and expressing gratitude. This gesture is an important etiquette learned from a young age and taught in households and schools. It’s so integrated into Japanese culture that even the deer do it! 

Feed the deer in Nara Park, one of the best places to visit in Japan, to experience this first-hand. Buy special biscuits for the deer, and give a bow before you hand over the treat. The deer will bow back!

7. Japan is one of the safest countries in the world

With an incredibly low crime rate, Japan is considered one of the safest countries in the world. It seems there are more police officers than petty crime incidents. Strict laws, a strong sense of community, and respect for all make this possible.

In fact, many Japanese people would instead leave a wallet on the ground or turn it in rather than steal the cash.

Tipping is not only unnecessary, but it’s also considered disrespectful in Japan. It’s one of the most interesting facts about Japan because it represents the wider acceptance that excellent service and respect are a part of the job.

Workers take pride in providing professionalism without expecting extra compensation. If you do happen to leave a tip, this may cause confusion, and many will politely refuse it.

With over 120 free-roaming cats and around 20 humans, Aoshima Island has exploded with tourism. However, a daily visitor cap prevents the elderly residents – both human and feline – from becoming overwhelmed.

An interesting fact about Japan is that KFC is not just a fast-food delight but also a Christmas tradition. Although Christmas isn’t a national holiday in Japan, many families celebrate by enjoying a crispy meal. 

This tradition dates back to a marketing campaign called “Kentucky for Christmas” in the 1970s, and it has now become an annual custom. 

If you’re traveling for the holidays, make sure you’re prepared by researching what to pack for Japan, including comfortable walking shoes, long-sleeved T-shirts, and thermal underwear. While Japan doesn’t get snow during Christmas, the weather is cold, but you’ll still get to enjoy the sun during the daytime. Remember to get a KFC sweater to enjoy Christmas like the locals do!

In Japan, it’s considered bad etiquette to douse sushi in soy sauce. The traditional Japanese way only allows a light touch, as soy sauce can overpower the intricate flavors of the fish and rice. 

In certain restaurants, the sushi chef will go as far as to brush on the perfect amount of soy sauce for you so you don’t get carried away.
