Our company endorses April Dream, which aims to make April 1st a day to share dreams. This press release represents the dream of "Marubishi Manufacturing Co., Ltd."
## ■ The Challenge of "Becoming a Manufacturer," My Father's Dream
Marubishi Manufacturing Co., Ltd. (Headquarters: Kasugai City, Aichi Prefecture, Representative Director: Seizo Tomatsu) has until now operated as a supplier to major manufacturers.
Amidst this, the previous generation had a dream.
That dream was:
**"Not to end as a supplier, but to become a manufacturer that can determine its own value."**
And,
"To deliver our own products to the world."
My father is still alive, and his dream is not yet dead.
I will inherit that dream as my own.
## ■ The Challenge of TOMA-TOP
Since 2000, Marubishi Manufacturing has been developing and selling its own brand product, "Toma Awning" (overseas name: TOMA-TOP).
This product is a rooftop installed on luxury pleasure boats equipped with a flybridge (upper helm station).
Its biggest feature is a **unique mechanism where the windshield opens and closes**, for which a patent has been obtained.
The name "TOMA" was chosen because the family name "TOMATSU" is difficult to pronounce overseas, indicating that the product was envisioned for global expansion from the outset.
## ■ The "Third Option" That Didn't Exist in the World
Until now, the choices for flybridge roofs were mainly:
Folding simple tents "Bimini tops"
Enclosures made of vinyl sheets "Enclosures"
These two were mainstream, not only in Japan but globally.
TOMA-TOP was developed as a new, unprecedented option that combines:
Streamlined, sporty design
Structural strength
Openable windshield
As a result, it has received a great response in Japan,
and as of 2026, it is adopted as an official option for cruisers from major domestic marine manufacturers such as Yanmar, Yamaha, and Toyota.
## ■ Second Challenge to the American Market
Once, when my father was in his 50s, he traveled overseas to spread this product worldwide.
However, at that time, he could not establish a local sales and installation system, and despite the positive response, it did not become established in the market.
After that, we focused on the domestic market,
but the time has come to challenge the world again.
