Ventilation Material Brand 'MIKATA' Celebrates 1st Anniversary - Surpasses 26,000 Units in Annual Shipments

Nihon Jukankyo Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Yutaka Hayashi) celebrates the first anniversary of its ventilation brand 'MIKATA', launched in May 2025.

In this first year, shipments have reached the equivalent of 26,000 housing units, and the lineup has been expanded to seven items that combine performance, ease of installation, and aesthetics. Marking this one-year milestone, we report on the progress made so far and future developments.

[Roof Ventilation Series 'R-series' & Eave/Flashing Ventilation Series 'E-series']

Background and Awareness of Issues Since the enactment of the Housing Quality Assurance Act in 2000, ventilation methods have become an essential technology for ensuring the durability of wooden housing in Japan. However, the existing market for ventilation materials has faced long-standing issues such as "insufficient aesthetic appeal despite good functionality" and "variations in precision depending on the installer."

To solve these problems, Nihon Jukankyo launched the 'MIKATA' brand in May 2025. The name 'MIKATA' incorporates our desire to offer new perspectives (Mikata) from various angles, remain an ally (Mikata) to diverse housing construction projects, and build 'three-way good' (Sanpo-yoshi) relationships among construction companies, craftsmen, and homeowners.

Our brand philosophy is based on three pillars: 'combination of honeycomb and different materials,' 'high installation ease suitable for any installer,' and 'product design that enhances the home exterior.' We have pursued product development that meets the trust of the site.

Major Achievements in the First Year The cumulative results for the first year since launch are as follows: - Annual shipment volume: Equivalent to 26,000 units - Current lineup: 7 items - Adoption area: Nationwide (excluding Okinawa)

With annual shipments reaching 26,000 units, our products have been adopted by construction shops, builders, and contractors nationwide, earning high praise in the residential ventilation market.

Expansion of Lineup Starting with 6 items at launch, we have now added the 'REV-15Model2' for wide fascia boards (Hirokamai) to the 'R-series,' creating a 7-item system: the 'R-series' (3 items) for roof ventilation and the 'E-series' (4 items) for eave and flashing ventilation.

- R-series: RFP-18, REV-15, REV-15Model2 - E-series: SEV-15, SEV-15FD, SEV-18, FVC-12

The newly added 'REV-15Model2' is adapted for roofs with wide fascia boards, which were difficult to handle with the popular 'REV-15,' thereby expanding our coverage area.

Future Direction In FY2026 (the second year of the brand), we will promote the following key measures: - Expansion of lineup: We will continue developing new products to solve more diverse on-site challenges and further expand our product lineup. - Strengthening brand communication: To deepen awareness and understanding of 'MIKATA,' we will create points of contact with customers and promote the brand's value and appeal from various perspectives.

Comment from the Brand Manager (Kobayashi, General Planning Department Manager) "The fact that our products have been adopted in so many homes in just one year confirms that designers and contractors were waiting for products that address their potential challenges. In the second year, we will focus on cultivating the brand so that more people will know about it and become fans."
