Mori Ranmaru — Who He Was and What He Is Known For

Mori Ranmaru was a page and close attendant of Oda Nobunaga who died beside him during the Honnō-ji incident in 1582. His real name was Mori Naritoshi (森成利); "Ranmaru" was a childhood name that stuck in later texts and culture. Two younger brothers, also Nobunaga's pages, died with him. Documents about him are extremely scarce — almost his entire image was built after his death.

Mori Ranmaru — Who He Was and What He Is Known For

Catastrophically little is known about the real Mori Ranmaru — even though everyone recognizes the face of his era. A few lines about his service to Nobunaga and one night in the burning Honnō-ji temple, where he died together with his two younger brothers. The image of the loyal page and the appearance that artists have been embellishing for centuries took shape after his death. Below is what is confirmed and what has been added.

Who Mori Ranmaru Really Was

Mori Ranmaru was a page (小姓, koshō) at the court of Oda Nobunaga, whose real name was Mori Naritoshi (森成利, 1565–1582); "Ranmaru" was a childhood name that displaced the official one in culture. The third son of Nobunaga's vassal Mori Yoshinari, who died in 1570, he entered the court early and by the age of sixteen was managing his lord's personal and administrative affairs, including the right to certify documents with his own signature. Ranmaru and his younger brothers Bōmaru and Rikimaru defended Nobunaga on the night of Akechi Mitsuhide's rebellion at Honnō-ji on June 21, 1582; all three died on the same day as their lord.

How Far His Lord's Trust Went

By the age of sixteen, Ranmaru had earned the right to certify Nobunaga's documents with his own signature — a far higher level of trust than mere personal service. In 1582, after the destruction of the Takeda clan, Nobunaga granted him Iwamura Castle in Mino, but Ranmaru never had time to govern the land: he remained with his lord until Honnō-ji.

Name and Kanji: 森蘭丸

森蘭丸 is read もりらんまる, but this is not the name by which his contemporaries knew him — according to documents, he was Mori Naritoshi (森成利). 蘭丸 is a childhood name (幼名, yōmyō): 蘭 means "orchid," 丸 is a typical suffix for boys' childhood names, as in "Ushiwakamaru" for the young Minamoto no Yoshitsune. The adult name 成利 uses the characters for "become" and "profit," but it was the childhood name that stuck in culture — Ranmaru died at seventeen, never having had time to grow up in the eyes of posterity.

森 — значение: forest, thicket — онъёми: シン — кунъёми: もり — 12 штрих(ов). 森 — "forest": 12 strokes, an N5-level character, composed of three repetitions of the character 木 ("tree"). This is Ranmaru's family name and one of the most common Japanese surnames today.

Why He Is Confused with the Mōri Clan

Ranmaru's surname is often confused with the equally famous Mōri clan (毛利) from western Japan, to which belonged, for example, Mōri Terumoto, the formal commander of the Western Army at Sekigahara. The characters are different — 森 ("forest") and 毛利 ("wool" + "profit") — but in romanization both clans turn into the same "Mori."

What Culture Added Beyond the Sources

Popular culture often portrays the relationship between Ranmaru and Nobunaga as wakashudō (若衆道) — a relationship between an older samurai and a young page, common in samurai circles of the time. The version is not documented: no source from the era describes their personal relationship directly, and the whole construct is a later interpretation of the scant facts about his exceptional closeness to his lord. A separate thread is his appearance: he is almost always drawn as a feminine beauty, although no contemporary descriptions of his appearance survive at all.

In games, Ranmaru is almost always beside Nobunaga: in Sengoku Basara he is a boy subordinate to Nobunaga, not a warrior on equal terms. In Samurai Warriors he is playable with weapons the historical page never had — paired chakrams — and with a deliberately androgynous appearance.

  • True: his real name was Mori Naritoshi, he served as a page from a young age, had the right to certify Nobunaga's documents, and died together with his brothers Bōmaru and Rikimaru at Honnō-ji.
  • True: in the games Sengoku Basara and Samurai Warriors he is a playable or significant character — these are confirmed titles.
  • Not confirmed by documents: a relationship with Nobunaga in the spirit of wakashudō — an interpretation, not a fact recorded in sources.
  • Fiction: his feminine appearance — a visual image invented by culture with no basis in contemporary depictions.
