Aomori Hiba, beloved as the prefectural tree of Aomori Prefecture, is resistant to rot and is strong, so it is used as building material for shrines and temples, and its scraps and sawdust are widely used in daily necessities, etc. Because the amount of wood that can be harvested is limited, Aomori Hiba itself is not as well known as Hinoki, and the amazing deodorizing and insect repellent effects it exhibits due to the large amount of rare hinokitiol it contains are not yet widely known.

Prior to the founding of tappi.lab Inc., a researcher who had his eye on Aomori hiba, which has excellent deodorizing, anti-fungal, and antibacterial properties, purchased Aomori hiba essential oil and, after repeated research and development, succeeded in emulsifying Aomori hiba essential oil and water without using alcohol or glycerin. To confirm the deodorizing effect, the researcher consulted with Otsukemono Kei, a company he frequently used at the time, and they agreed to conduct deodorizing experiments on delivery vehicles and rental fixtures at event venues. After repeated experiments over a period of approximately four years, the current "Nitori MASH" was completed. When the researcher was considering selling "Nitori MASH" after its completion, the people at Otsukemono Kei provided support, including introductions to related parties, and the decision was made to found tappi.lab Inc.
