DENZEN Co., Ltd.

DENZEN Co., Ltd. (株式会社伝然) is a Japanese company based in Higashiosaka, Osaka, founded on 17 December 2018 and led by representative director and CEO Yuichi Oga. Its name is a play on words meaning "to pass on nature" (自然を伝える), and its stated mission is to popularize household food-waste processors so that society shifts from a culture of discarding food scraps to one of processing them at home, thereby helping pass on a rich natural environment to future generations. The company describes its vision as creating value that leads to "living with a rich heart" and realizing a society that can pass nature on to posterity, with a philosophy of "creating a world overflowing with smiles, together, with a heart of compassion." DENZEN's core business is the planning and sale of the household food-waste processor NAXLU (ナクスル). NAXLU is marketed as a hybrid machine that combines drying and bio (microbial) methods: food scraps are broken down by enzymes and microorganisms, and the unit is designed to address the common complaints about earlier food-waste processors — odor, effort, noise, and electricity cost. The company claims a one-second disposal action (simply open the lid and drop scraps in), removal of 99.84% of malodorous components through a three-layer hybrid deodorizing system, low power consumption of 60W with automatic energy-saving, and operating noise below 30 dB. The flagship model listed on the official site is the FD-015M, with a suggested retail price of 139,700 yen (tax included) and a promotional price of 127,600 yen (tax included) with free shipping. Beyond the core NAXLU line, DENZEN has introduced OneNyaNAXLU, an evolved version of NAXLU designed to also process pet feces, reflecting the machine's strong deodorizing capability. The company sells through its own website and, according to its news section, has expanded into national Bic Camera Group stores. It also recruits sales agents and operates social media accounts on Instagram, Twitter, and Facebook. DENZEN positions itself as aiming to be "the best in the world" and No. 1 in the food-waste processor industry, and it frames its products as part of a broader cultural change in clothing, food, and housing needed for a sustainable society.

DENZEN Co., Ltd. was established on 17 December 2018 in Higashiosaka, Osaka, Japan, with Yuichi Oga as representative director and CEO. The company was founded around a single core product concept: a household food-waste processor that would eliminate the long-standing drawbacks of existing machines. Its corporate name, 伝然 (DENZEN), is explained by the company as meaning "to pass on nature" (自然を伝える), tying the business directly to an environmental mission. From the outset, DENZEN's business has been the planning and sale of the household food-waste processor NAXLU. The company describes NAXLU as a hybrid system that combines drying and bio (microbial) decomposition, and it markets the machine against four common complaints about earlier food-waste processors: the effort of use, odor during and after processing, electricity cost, and noisy operation. According to the official product page, NAXLU addresses these with a one-second disposal action, a hybrid deodorizing system that removes 99.84% of malodorous components, a 60W energy-saving design with automatic power saving, and operating noise below 30 dB. The flagship model is the FD-015M, listed at a suggested retail price of 139,700 yen (tax included) and a promotional price of 127,600 yen (tax included) with free shipping. The company has since expanded the NAXLU family. It introduced OneNyaNAXLU, described as a significantly evolved version of NAXLU that can also process pet feces, leveraging the machine's deodorizing capability. DENZEN also sells consumables such as UV lamps and bio material, and it provides support content including FAQs, usage and specifications, information on subsidies, and guidance on what can be put into the machine. In distribution, DENZEN sells directly through its own website and has announced sales through the Bic Camera Group nationwide, marking a step from direct-to-consumer sales into physical retail. The company also recruits sales agents and maintains social media accounts on Instagram, Twitter, and Facebook. In its corporate messaging, DENZEN states that it aims to be the best in the world and No. 1 in the food-waste processor industry, and it frames its mission as contributing to a sustainable society by changing the culture of clothing, food, and housing and by providing experiences that nurture a love of nature in the next generation. The company has also issued consumer-protection notices, including a warning about counterfeit and non-genuine UV lamps for food-waste processors.
