Ranjatai: The “Ruler’s Incense” Preserved in the Shosoin
There is a popular story about Ranjatai:
“Only those recognized as the rulers of Japan were permitted to cut off a piece of it and enjoy its fragrance.”
According to this image, receiving permission from the Imperial Court to open the Shosoin Repository, cut a small piece from the famous aromatic wood stored inside, and burn it as incense was almost a declaration that one had been acknowledged as the ruler of the country.
And when you look at some of the names associated with Ranjatai, the story sounds quite convincing.
Ashikaga Yoshimitsu, Ashikaga Yoshinori, Ashikaga Yoshimasa, Oda Nobunaga, and Emperor Meiji.
The most famous case is probably Oda Nobunaga.
In 1574, Nobunaga requested permission from the Imperial Court to open the Shosoin and have pieces cut from Ranjatai. Even today, a paper label attached to the wood marks the place traditionally associated with Nobunaga’s cutting.
But what exactly is Ranjatai?
Ranjatai is an enormous piece of aromatic wood still preserved in the Shosoin in Nara. Its official name is Ojukuko, while the name “Ranjatai” is written with characters that cleverly contain the characters for To-dai-ji — Todaiji Temple — hidden within them.
The Shosoin itself is an extraordinary historical institution.
Its origins are closely connected with the death of Emperor Shomu in the eighth century, when Empress Komyo dedicated many of his personal belongings to Todaiji. Over time, numerous objects connected with the Imperial Court and the temple were preserved there.
Its collection includes textiles, musical instruments, vessels, furniture, documents, and works of art showing connections not only with Tang China and the Korean Peninsula, but also with cultures further west along the Silk Road.
In that sense, the Shosoin is much more than an ancient warehouse.
It is something like a gigantic historical time capsule, preserving objects that allow us to look directly into the material culture of Nara-period Japan and its connections with the wider Eurasian world.
So the idea of being allowed to cut into an object that had been protected inside such a repository for centuries certainly sounds like an extraordinary privilege.
However, the historical record makes the situation more complicated.
Not everyone who obtained Ranjatai could reasonably be described as the ruler of Japan.
One particularly interesting example is Hatakeyama Yoshifusa, the shugo lord of Noto Province in the early sixteenth century.
Yoshifusa was an important regional lord, but he was neither shogun nor ruler of the country.
Nevertheless, court records indicate that he received Ranjatai from the Imperial Court, apparently on more than one occasion.
Yoshifusa maintained close relations with the court and repeatedly sent money and regional products from Noto as gifts. After receiving Ranjatai, he also sent money in return.
This suggests that Ranjatai was not simply a certificate proclaiming:
“This man is the ruler of Japan.”
What mattered was not only military control over the country.
A person also needed the social standing to maintain relations with the Imperial Court, the ability to participate in the courtly world of ritual and gift exchange, and enough wealth to sustain those relationships.
Receiving Ranjatai could therefore serve as a visible symbol of political access, status, wealth, and connections with the Imperial Court.
The physical condition of Ranjatai itself makes the story even more interesting.
Today, labels identify cutting sites associated with Ashikaga Yoshimasa, Oda Nobunaga, and Emperor Meiji. But examinations of the wood have found many more cutting marks than those three alone.
In other words, the few famous historical figures whose names are attached to the wood were clearly not the only people to receive portions of it.
So the simple formula —
“If you could cut Ranjatai, you were recognized as the ruler of Japan”
— is probably closer to a later popular legend than to the full historical reality.
Of course, when someone as powerful as Oda Nobunaga obtained permission to open the Shosoin and cut Ranjatai, the act carried obvious political significance.
But Ranjatai was never exclusively reserved for men who ruled the whole country.
It may be more accurate to see it as an exceptionally prestigious object that demonstrated something slightly different:
How close could you get to the Imperial Court?
Did your family possess enough status to participate in that world?
And did you have enough political and financial power to maintain that relationship?
Seen from that perspective, Ranjatai is much more than an old piece of fragrant wood.
Who requested it, who received it, who cut it, and what they offered to the court in return all tell us something about the relationship between Japan’s warriors and the Imperial Court over many centuries.
The cutting marks left on a single piece of wood have become a record of political relationships themselves.
It is, in a sense, a piece of political history that still carries a fragrance.
And one final note:
Ranjatai is now an irreplaceable historical artifact. So no, unfortunately, cutting off a piece without permission and declaring yourself the new ruler of Japan is no longer a viable political performance.
