Iga and Koka: Japan’s Famous Ninja

During the Warring States period (the late 15th to the late 16th century), the ninja supported warlords as specialists in numerous intelligence-gathering and combat operations. In modern terms, they were spies and left behind no traces, so much of what they did is still shrouded in mystery. Though the ninja are shrouded in a veil of mystery, there are many locations to explore and experience ninja culture in the Chubu area. The area is home to the Iga and Koka ninja, the most famous of all ninja schools. Before you make your trip to Chubu, brush up on some basic information about the ninja schools and learn about the places you can visit.

The Public Face of Ninja

Most people think of ninja as warriors with black costumes and formidable skills, but most were merchants and farmers. Fighting was the last resort for ninja. In most cases, their primary role was intelligence gathering to gain a picture of enemy movements and to manipulate information to obstruct enemy operations. So, it is no wonder tradespeople at teahouses, where many people pass through, and at inns where influential people would stay, were actually working as ninja.

The most common occupation at the time was farming. It was easier to blend in with crowds when you knew the land well, and carrying a sickle, was usual for farmers and wouldn't look like a ninja weapon in their hands. Ninja clothing is also known to be easy to move in and inconspicuous for farm work.

Ninjutsu (Art of the Ninja)

The ninja used a breathing technique called Futaeibuki (double breath) to increase their endurance.

A ninja's role was conducting espionage, and it was essential to stay alive and return with information quickly and reliably. To this end, the ninja excelled at hiding and escaping from their enemies. The ninja arts are referred to as Ninjutsu, with techniques in psychology and pharmacology.

Typical techniques included: the art of disguise, where the ninja disguised themselves as monks or street performers, the art of the water spider, allowing them to cross water like a spider and the art of fire, to distract opponents with pyrotechnics, typical moves in any spy movie.

Koka and Iga: The Representatives of the Ninja

Ninja organizations are said to have existed throughout Japan (some say there were more than 70). The most famous of these organizations are the Iga and Koka ninja. The regions they operated in were only 20 km apart, in a straight line, and regularly interacted with each other.

Iga Ninja: Contracted Professionals

The Iga Ninja lived in the northwestern part of present-day Mie Prefecture. They were known for their skill in combat, and their specialties were pyromancy, using gunpowder, conjuring for self-defense, and warding off evil spirits. Interestingly, their relationship with their employers was through cash contracts. They were a group of professionals who protected their employers but did not have more than a professional relationship with them.

Step Into the World of Iga Ninja

Lots of photo spots!

Koka Ninja: Loyal Warriors

The Koka ninja lived in and around the city of Koka in what is now southern Shiga Prefecture. The Koka ninja were noted for their knowledge of medicinal herbs and medicine and excelled at magic tricks using poisons and medicine. Even today, many pharmaceutical companies operate in Koka. The biggest difference between the Koka and the Iga ninja was their loyalty to their lord. Koka ninja were known as Koka bushi because they swore absolute loyalty to their lord and risked their lives to protect them. Additionally, when problems occurred, representatives from each house would gather to make decisions, suggesting a high sense of unity and solidarity.

Legendary Ninja Hattori Hanzo

Fukawa-ya

Hattori Hanzo is the most well-known ninja, and the Hattori family are the original ninja retainers of the Tokugawa shogunate, serving for many generations and commanding both the Iga and Koka schools of ninja. The name Hattori Hanzo is hereditary, and it is believed that there were about 12 Hattori Hanzos, and their descendants run Fukawa-ya, a long-established confectionery shop in Sekijuku, in business for roughly 380 years.

Aki Hattori

Aki Hattori's family is in the 14th generation of the family, counted from written records, and possibly the 19th generation, if one considers the legends. Aki Hattori's family inherited books passed down through generations, including oral traditions. One of the most memorable episodes, characteristic of descendants of ninja, is how his grandparents taught him to walk into people's hearts from when he was a child. He says this lesson is about not trying to be liked but opening the hearts of others, and it is a valuable lesson in his current business.

Seki no To

Seki no To is a confection made in the image of white snow piled up on Mount Suzuka. A few years ago, a scientific study of Seki no To revealed that it remains preserved for as long as two years. Hattori says that the ninja had a wealth of knowledge in pharmacology and medicine, which may have contributed to the creation of Seki no To, a long-lasting and tasty food. Seki no To is available in Sekijuku and department stores nationwide.
