Also known as oud, agar- or aloes-wood, Jinkō is more valuable by weight than gold, its rich, captivating fragrance treasured by many cultures and religions throughout history. This dark, mystical, aromatic resin forms in the heartwood of aquilaria trees native to southeast Asia, which are pale, light and odourless – until they become damaged and infected by a certain fungus. The resinous wood has a high density and sinks in water, hence jinkō is written in kanji as “sinking incense”. According to folklore, agarwood first appeared in Japan when it drifted ashore onto Awaji island in the 6th century, where the locals picked up on its heady scent when burned. Kyara, found in the highlands of Vietnam, is the most prized type of jinkō – so precious in fact that among Japan’s National Treasures is a priceless piece of kyara named Ranjatai, which is over a thousand years old.
