A Treasured Creation - Season 4 / Year 2022

Hara Masaaki makes white charcoal called Kishu Binchotan in the deep forests of Wakayama Prefecture. He thinks of himself as a guardian of the ancient woods. His charcoal provides the country's top chefs with a stable, high heat source with no odor and little smoke -- an essential fuel for grilling. But now, some kilns lie abandoned. All that remains is the metallic sound of Binchotan reverberating from oak trees. Through the haze of smoke, we look at the memories of those families who've passed down their craft in the mountains.

Three generations of the Tomi family have been producing a unique kind of handmade washi paper that is blackish-brown instead of the customary white. This is achieved by something that otherwise had just gone to waste. Tomi Kazuyuki states, "My grandpa felt bad watching cedar bark being thrown out at timber mills so he devised a new method to utilize it." The family tradition incorporating all of the wilderness into their papercraft lives on in the Noto Peninsula. We take a look at this source of creation.

One of Japan's most prized textiles comes from a subtropical island where the makers still hew to the methods of 1,300 years ago. Using indigenous plants and ponds of iron-rich mud, the artisans of Amami-Oshima create luxurious silk pongee, threading the island's long history of poverty and oppression into their craft.

The Chin kiln of Kagoshima has been turning out intricate pottery for more than 400 years. The signature openwork and fine detailing was a sensation at the Paris Exposition of 1900. Now the current, 15th-generation head of the family is on a mission to develop new clay from local volcanic earth to bring out an ultimate whiteness in their Satsuma ware.

Rows of black ceramic pots sit in the sun as rice and koji malt ferment inside. For more than a year, the enzymes will turn the mash into prized amber vinegar with only the gentlest interventions from the brewers. "Every pot turns out different faces," says vinegar artisan Sakamoto Hiroaki. "We try to listen to what the magical fungi are saying." We explore the centuries-old methods behind the making of Kurozu vinegar.
