Boasting an impressive height of up to 60 meters, this structure spans a total length of 1.2 kilometers and a width of 12.5 meters, harmoniously blending with the surrounding landscape designated as a nature reserve. In addition to the "Saale Valley Bridge," various civil engineering projects, photos, and articles related to civil engineering are also featured, so we hope you will take a look.

The fragrance that spreads the moment you step inside enhances the company's brand image, making it more refined.

Would you like to design a first impression with fragrance and enhance your company's appeal? Majesta Fragrance is currently accepting requests for free trial installations. If you are interested in creating a fragrant atmosphere, please feel free to contact us.

  • NEW
  • PRODUCT

We have introduced the Majesta Fragrance commercial diffuser to a fitness gym located in the city. Gyms and sports clubs tend to trap sweat and humidity, making them spaces where odor issues can easily arise. That’s why "scent design (branding)" that dramatically changes the overall impression of the space is highly effective. - The diffuser being used is the [MF-01]. It is a stylish tower-type diffuser available for a monthly fee of 8,800 yen (tax included). This model is space-saving and blends well with any interior. - The scent being diffused is [Forest Green]. It is a refreshing fragrance that blends the crispness of bergamot with the natural scent of green, creating a clean and pleasant atmosphere. It enhances concentration during exercise while providing a refreshing and comfortable space. A free trial installation is available. "I don’t know what scent would suit my gym." "I want to try out the different scents available." For such stores, Majesta Fragrance offers a free trial installation. If you are considering space branding or odor control, please feel free to contact us.
