Mochizuki Chiyome is a name deeply connected to Japanese legends and folklore. She is often described as a 16th-century noblewoman and a talented poet. In many popular stories, she is also known as a leader of female spies. These female ninjas are called kunoichi. These tales suggest she served the powerful Takeda clan during the Sengoku period.

While her name is famous, historians debate whether she was a real person or a character created by later writers.

The most detailed stories about Chiyome come from a writer named Shisei Inagaki. In his 1971 book, *Investigation of Japanese History*, Inagaki provided a specific version of her life. He claimed that Chiyome was married to a man named Moritoki Mochizuki. According to Inagaki, Moritoki died during the Fourth Battle of Kawanakajima. He also claimed that a leader named Shingen issued a written permission to Chiyome. This document supposedly allowed for the creation of a "miko village."

In this version of history, the miko, or shrine maidens, functioned as spies for the clan. This process turned a religious group into a network of kunoichi.

Modern historians have raised significant doubts about these specific claims. Katsuya Yoshimaru, an associate professor at Mie University, has studied these accounts closely. He argues that Chiyome may not have existed at all. Yoshimaru points out several errors in Inagaki's historical research. First, there are no historical documents that describe the details of the battle Inagaki mentioned. Second, records do not show that Moritoki died in that specific battle. Third, the written permission from Shingen that Inagaki describes cannot be found.

Yoshimaru notes that many such historical permissions are actually forgeries.

The connection between miko and ninjas is also questioned by experts. Yoshimaru states that the idea of miko acting as spies is groundless. He believes this idea was simply a guess made by Inagaki. Furthermore, Inagaki cited a 1930 book titled *History of Japanese Miko* by Taro Nakayama. However, that book makes no mention of ninjas or spies. The link between these two roles only appears in Inagaki's own writing. This suggests the legend grew from a single source rather than ancient records.

Despite these historical doubts, Chiyome's popularity grew rapidly in the late 20th century. Her name became widely known after a 1991 article in the magazine *History Reader*. This special issue focused on the "definitive types of ninja." The article labeled Chiyome as an "upper ninja," or *jonin*. Yoshimaru points out that there was no such rank in the actual historical ninja hierarchy.

Even with these inaccuracies, the article helped cement her status as a legendary figure in the public imagination.

Today, Mochizuki Chiyome is a frequent character in modern popular culture. She appears in many different video games, ranging from strategy games to role-playing games. In the *Samurai Warriors* series, she is a trainer for the kunoichi character. She also appears in *Samurai Warriors 2* as the mistress of Shingen. Other games like *Puzzle & Dragons* and *Toukiden: The Age of Demons* include her.

In *Pokémon Conquest*, she is a non-playable character who uses Ground and Dark type Pokémon. She even appears in the *Fate/Grand Order* series as an Assassin-class Servant.

Her presence extends beyond games and into books and films as well. The film *Sanada Yukimura no Bōryaku* features actress Yatsuko Tanami playing her role. She is also a major character in the young-adult historical novel *Risuko* by David Kudler. In the game *Shadow Tactics: Blades of the Shogun*, a character named Aiko belongs to a kunoichi clan run by a "Lady Chiyo."
