Inspired by the gentle power of nature, this eco-friendly humidifier requires no electricity—only water and time. Crafted from locally sourced Japanese Cypress (Hinoki), it uses natural evaporation to add refreshing moisture to your space. Compared to a simple glass of water, its evaporation speed is up to eight times faster, filling the air with comfortable humidity and a subtle Hinoki aroma.
Shaped like the sail of a yacht, the humidifier’s form is as striking as it is functional. The sail is made from ultra-thin sheets of shaved Hinoki wood, so delicate that sunlight passes through, creating a soft, glowing beauty. Place it on your desk, by the window, or beside your coffee table, and let its calming presence accompany your daily rituals—whether reading, working, or enjoying a quiet cup of tea.
Choose between two sizes depending on your lifestyle and environment. Both offer the same elegant design and natural humidification, with different capacities to match your needs.
For best performance, we recommend rinsing the sail gently before first use to prevent breakage and improve water absorption. Because the Hinoki is uncoated natural wood, the immersed section may darken or collect dust over time. Lightly rubbing with your fingertips during cleaning will help maintain performance, though we suggest replacing the sail after one season. Replacement sails are available separately.

In a workshop where the scent of fresh Hinoki lingers in the air, skilled artisans cut, wedge, and assemble each Masu Mug with unwavering precision. Every joint is a reflection of centuries of accumulated knowledge; every surface is polished to reveal the wood’s natural warmth. Here, in Ogaki, the Masu craft is not merely a profession—it is a heritage carried forward, a dialogue between past and present, wood and hand, tradition and everyday life.

For over 1300 years, the Masu has played an important role in Japanese tradition. Originally a measuring cup for foods such as rice and soy sauce, the Masu was used to measure rice when it was common as a form of currency. For the Japanese people, the Masu was as valuable and important as the rice it contained, and this tradition remains an essential part of the lives of people today.
More recently, the Masu has become widely acknowledged as a vessel for serving Sake, as well as a symbol of good luck.
The term “Masu” translates to “growth” in Japanese, and is thus an icon of prosperity and great happiness. Masu is also used in sacred rituals, and holy offerings are often presented to the spirits in the Masu box. On the day before the official start of spring, it is customary for farmers to offer beans in a Masu box to pray for a rich harvest.Masu is unique because it is put together wedging together precisely cut pieces of wood and applying a very small amount of adhesives, without the use of any nails.
Because of its use in exquisite architecture, the Japanese Cypress, better known as Hinoki, is regarded as a great luxury in Japan. Famous for its crisp fragrance as well as its versatility as building material, Hinoki is a favorite choice for hot spring baths. The Japanese Cypress has been the wood of choice for the construction of ancient works of architecture such as the Horyuji Temple, the oldest wooden structure known to date.
The fresh fragrance of the Japanese Cypress has been scientifically proven to have a relaxing and refreshing effect. The scent particles also give this special wood an antibacterial quality, making it an ideal choice for use as kitchenware and bath items.
No trees are cut specifically for the purpose of making a Masu box. Masu boxes are made by effectively recycling wood that did not meet building material standards because of its shape or size.
80% of all Masu boxes produced in Japan are made here in Ogaki city. Ogaki is a known producer of Japanese Cypress lumber, and the Masu industry has grown hand in hand with the Cypress trade. In its prime, about 2,000,000 Masu boxes were produced and distributed annually from Ogaki city alone.
