Thirteen Generations and Not One Review
The kiln fires the iron flecked stone its Arita neighbours throw away. What that porcelain is like to live with, nobody has written.
Did not pass
We already trust this designer. Oji Masanori’s work appears on SleekNova three times through Futagami, the 127-year-old brass foundry he collaborates with.
When we found that Masanori also designed the porcelain collection for a 350-year-old kiln in Arita, we expected the research to be straightforward.
It was not.
The Kiln
JICON is a porcelain brand born from the Touetsugama kiln, founded 350 years ago in Sasebo City, Nagasaki Prefecture, later relocated to Arita in Saga Prefecture.
Imamura Hajime, the 13th-generation heir, became independent in 2014 as IMAMURA Porcelain and launched JICON in collaboration with Masanori. His wife, Maki Imamura, works alongside him. Together they make each piece by hand in their studio adjacent to a showroom in Arita.
His father’s work sits in the Kyushu Ceramic Museum.
The brand name combines the characters for “porcelain” and “now.” In Buddhist words, it means “seize the day.”
The Porcelain
What makes JICON distinctive is a deliberate material choice. Traditional Arita craftsmen discard porcelain stones that contain natural iron pigments, prizing only the purest white material.
JICON uses those rejected stones. They fire them at higher temperatures than conventional methods, producing porcelain that is stronger and heavier than standard Arita ware.
The glaze, naturally derived from straw ashes, is not thoroughly stirred before application, allowing brown iron spots and coarse particles to emerge at the surface.
The result is an unbleached whiteness with a half-matte texture. Not the sleek, glamorous blue-white of traditional Arita porcelain, but something warmer and more tactile.
According to the maker, the texture slowly changes with use, a process they call “cherishing.”
When Nalata Nalata co-founder Stevenson Aung visited the studio in Arita, Imamura showed him a bucket in the workshop labeled “Oji Masanori’s Special Glaze.”
Masanori developed the glaze formula, designed the logo, and shaped every piece in the collection. The Heishi vase stands 7.5 inches tall on a 2.5-inch base, tapered and clean, designed to make a single stem look intentional.
What We Found
The heritage verification was among the strongest we have recorded. Six independent sources, from Spoon and Tamago to IPPINPROJECT to Studio Saum, corroborate the same founding story with no contradictions.
Spoon and Tamago’s editor described JICON as “truly a well-designed product” after seeing the collection in Tokyo.
Eight premium retailers stock the brand across New York, Brooklyn, Amsterdam, Minneapolis, and Melbourne. At the time of our research, Misc Store Amsterdam had sold out of every JICON product in their collection.
What we did not find: a single customer review. Anywhere.
JICON is not sold on Amazon. It is not sold on Etsy. Nalata Nalata’s product pages carry no review widget. Neither does IPPINPROJECT, Studio Saum, nor any of the other stockists.
We searched Google, Reddit, and every platform in our protocol. The result was the same each time. Zero.
The Score
The Heishi vase earned an 8 for visual appeal, an 8 for discovery factor, and an 8 for gift-scene potential. Those are strong scores.
The confidence score, which measures the verifiability of trust signals, came in at 55 out of 100, producing a trust score of 5.5.
That trust score brought the final SleekNova score to 7.63, which falls below our 8.0 threshold.
The product passed every individual gate. No score fell below its rejection floor. The heritage is museum-grade. The designer is already validated in our pipeline. The demand is real.
But our system requires verifiable customer evidence, and for JICON, that evidence does not yet exist in any public forum.
What Would Change
Verified customer reviews across any established platform would shift the confidence score. The heritage and stockist signals are strong enough that even a modest review base would likely clear the threshold.
The product itself is not the problem. The verification gap is.
At $55, this is a porcelain vase from a 350-year-old kiln, designed by a maker whose brass work we already recommend. We wanted to feature it. The math said not yet.
