Did you know that the names of the Otsutsuki clan members introduced in the Naruto and Boruto series carry special meanings? The significance of these names and their importance is derived from Japanese folklore and history, which is quite renowned in this country.
1. Kaguya Otsutsuki – The Story of Princess Kaguya

Kaguya Otsutsuki is inspired by the story of Princess Kaguya, known in Japan as Kaguya-hime no Monogatari.
Not only does the name hold significance, but many elements associated with Kaguya Otsutsuki are also derived from this folktale. The Otsutsuki clan itself can be understood as a tall bamboo tree, which is one of the important points in this Japanese folktale.
Additionally, Hagoromo means a flowing cloak and is used as the name for Kaguya Otsutsuki’s eldest son. The significance of the flowing cloak is also closely related to this folktale.
2. Momoshiki Otsutsuki – Momotaro

Momoshiki, Kinshiki, and Urashiki have similar narrative backgrounds. In the case of Momoshiki, he is portrayed as the hero Momotaro.
Aside from the name, there are not many points from Momotaro that are reflected in the character of Momoshiki. If you consider the chakra fruit that Momoshiki consumes, it relates to the story of Momotaro who emerged from a giant peach.
3. Kinshiki Otsutsuki – Kintaro

Next is Kinshiki, inspired by the tale of Kintaro. Besides the name, Kintaro’s characteristics in the Kinshiki character include strength and bravery. Similar to the story of Kintaro, he possesses a strong physique and wields a giant axe.
4. Urashiki Otsutsuki – Urashima Taro

In Japanese folklore, the name Taro is often associated with characters like Urashiki and Urashima Taro. Urashima Taro is a tale about a fisherman who helps a turtle and is taken to Ryugu-jo under the sea, where he meets Otohime and faces a time-related curse that traps him for 100 years (in real time).
Urashima Taro opens a tamatebako, a treasure box containing beautiful items given to him by Otohime. Besides the tale where Urashiki uses a turtle for time travel, there are other unique elements as well. The technique that Urashiki uses to time travel can be likened to the tamatebako, named Ryugujo.
Furthermore, Urashiki also employs a turtle named Karasuki to navigate through time. The story of Urashima Taro is indeed connected to the concept of time, making it fitting with this narrative.
5. Isshiki Otsutsuki – Issun Boshi

Jigen, also known as Isshiki Otsutsuki, is inspired by the Japanese folklore character Issun Boshi.
Issun Boshi is known as a diminutive hero, only one inch tall but very strong.
This tiny stature relates to Isshiki Otsutsuki as his strength can be magnified or diminished based on his physical form or the objects he possesses. Thus, Isshiki’s powerful abilities can manifest at unexpected moments, causing significant destruction to his foes.
