MF Services

MF, as a manufacture specializing in Yojo material, always try to fulfill the services that cannot be made available by any other.

We design and develop products by ourselves.

We design and develop products by ourselves.

Just after MF started its business, the protection materials available in construction sites was few sheets.

It was general for the workers to protect some spots by adapting packaging materials and veneer board.


In selling Yojo sheet, we found unreasonableness and inefficiency in construction sites and have developed materials specializing in Yojo to improve the situation.

MF is a manufacture that has been always facing customers and offering what is necessary for them.

That is the reason MF has a lot of original products ,such as "Dankichi", "Wakuzo", and "Toranosuke", as main Yojo materials.
As you may have noticed, a lot of our products have unique names, such as "Dankichi","Yukanosuke",and "Wakuzo".

We do not name a product in meetings: it is the staff who develops the product who gives it a name.

The staff who has the deepest attachment to the product gives a name, which leads to a strong wish to expect the name to be remembered. "52AD","Yuwaku no Tenshi","Shonan Board": once you hear these names, you shall never forget them.

What we can do as a manufacture specializing in Yojo material

What we can do as a manufacture specializing in Yojo material

A lot of products of MF have spread in construction sites: we developed Yojo cover and Yojo paper for columns and set them out into the world.

We consider it our strong point that all the staff can cooperate and work together intensively focusing on Yojo material.

Though limited in the field of Yojo material, we have larger number of products than any other company."

A company specializing only in Yojo material might be really rare, but we think it the reason that we can meet the detailed demands that other companies cannot.

We deliver our products directly where they will be used, pursuing the convenience for customers.

MF never fails to give careful consideration in the delivery of products.
Measures suited to each occasion are necessary in the building industry, so we are willing to deal with any problem concerning the delivery, suzh as sudden orders, additional orders, and specified dates. To reduce the delivery time and cost, MF delivers the products directly to the place where they will be used.

*About direct delivery: please give us some information, such as address, map, and name of building, with an order form."
We can check delivery dates and tracking numbers any time during our business hours (9:00 - 17:00).

*Only in Japanese Service.

Our commitment to safety and environment

It is not only buildings but also environment that we "protect." MF thinks so.

Eco-guard・Shonan Board・Yukanosuke・Dankichi

Yojo materials basically have the purpose to "prevent dirt and scratches", but in the development of products, the consideration for the environment is also important and indispensable. We have to "prevent pollution and scratches" when we dispose them.
Yojo materials are used temporarily, that is, they are necessarily removed when the work is completed.
Therefore, the materials that cannot be reused must be disposed of.
In the consideration for the environment, MF manufactures single use products from only one material as much as possible.
The products such as "Eco-guard", "Shonan Board", "Yukanosuke", and "Dankichi" are made only of regenerated pulp. It saves the trouble of segregating, and this attempt is necessary in order to make work efficient.

Easy Recycling

We put these easily-recyclable single material products into our original category called "Easy Recycling". A product labelled as "Easy Recycling" is manufactured from single material, and it is easy to collect as recyclable material.
