"Sugi Layer Board" is a new type of laminated wood made from Echigo cedar. Compared to single boards, it has less warping and maintains the same strength as solid wood. Additionally, when multiple pieces are joined together, it creates wide boards that are difficult to achieve with a single piece, and stacking them counteracts the warping force on both sides, stabilizing the material. 【Features】 ■ The unique white and red colors of cedar can be combined in a balanced manner. ■ Less warping compared to single boards, making it easier to process. ■ A warm, natural finish characteristic of cedar. ■ The adhesive used is F☆☆☆☆, free from formaldehyde and organic solvents, ensuring safety and peace of mind. ■ Maintains the same strength as solid wood. *For more details, please refer to the PDF materials or feel free to contact us.

"PW Guard III" is a wooden fall prevention fence that is thoroughly committed to using locally sourced cedar wood. It complies with the installation standards for pedestrian and bicycle fences (Type P). The wood undergoes anti-corrosion and anti-termite treatment (JIS A 9002) as a basic specification, and by ensuring proper drying and quality control, the anti-corrosion effect is achieved. 【Features】 ■ Uses locally sourced cedar wood ■ Consideration for the safety of passersby ■ Capable of matching the aesthetic image of the surroundings ■ Complies with pedestrian and bicycle fence (Type P) standards ■ Anti-corrosion and anti-termite treatment (JIS A 9002) specification *For more details, please refer to the PDF document or feel free to contact us.

The "Wooden Monotone Bench" is a solid wood bench with a seat that skillfully combines the color differences between the sapwood (white) and heartwood (red) of cedar. Unlike industrial products, it offers a gentle texture, comfortable seating, a pleasant feel, lightness, and sturdiness. We have supplied this bench to schools and public facilities, receiving high praise. 【Features】 ■ Made from locally sourced cedar wood ■ Allows you to experience the warmth, texture, and quality of nature ■ Made from safe materials that are gentle on people ■ Finished with wood protection paint (natural paint type) to maintain texture ■ No metal fittings used *For more details, please refer to the PDF document or feel free to contact us.

"Wooden camber (wedge)" is commonly used for adjusting gaps in steel supports during underground construction of buildings, bridge abutments, and tunnel work. We offer three shapes: Type 1, Type 2, and Type 3. We can also manufacture special dimensions other than standard sizes, so please feel free to contact us. [Features] ■ For adjusting gaps in steel supports ■ Special dimensions other than standard sizes can also be manufactured *For more details, please refer to the PDF document or feel free to contact us.

The 'Hanjibashi' is a prestressed wooden deck bridge made of solid cedar, designed exclusively for agricultural vehicles and spanning over fields. The assembly and tensioning of the deck beams are all conducted on-site, allowing for a wide range of installation conditions. It is lightweight relative to its strength, which reduces the need for heavy substructures, and it can also accommodate emergency temporary structures and areas requiring short-term restoration. 【Features】 ■ All assembly and tensioning of the deck beams are done on-site ■ Capable of accommodating a wide range of installation scenarios ■ Lightweight relative to strength, reducing the need for heavy substructures ■ Can also accommodate areas requiring short-term restoration, such as emergency temporary structures ■ Achieves low carbon society with lightweight, short construction periods, and low construction costs *For more details, please refer to the PDF materials or feel free to contact us.

The "Ladder Beam Construction Method" is a technique used for foundation reinforcement when the ground supporting the main structure is weak, or when the geology and superimposed loads are uneven. Since it is buried underground, it is resistant to decay, and there is no need for preservative treatment for the foundation wood, cross beams, or foundation work. 【Features】 ■ Foundation wood and cross beams are arranged in a ladder shape ■ The basic processing of the wood is a drum drop ■ Since it is processed in advance at the factory and then delivered to the site, assembly management is easy ■ Prevents uneven settlement of the facility ■ Resistant to decay *For more details, please refer to the PDF document or feel free to contact us.

The "Kankyo Bridge" is a wooden bridge that utilizes cedar logs in their natural state. It does not require piers and can accommodate a maximum bridge length of 12 meters. It is lighter than concrete or steel bridges, reducing the load on the substructure. Additionally, it can be widely adapted from pedestrian bridges to forest road bridges through girder adjustments, and durability can be improved through anti-corrosion treatment. 【Features】 ■ Girders are sourced from locally harvested thinning materials ■ Accommodates a maximum bridge length of 12 meters ■ Easy assembly of girders on-site ■ Lightweight girders allow for installation with a small crane ■ Reduces the load on the substructure *For more details, please refer to the PDF document or feel free to contact us.

The "Wooden Drain Cover" is a lightweight and durable wooden drain cover made by Murooka Forestry Co., Ltd., which is well-versed in local cedar wood. It solves problems such as "the steel plate covers are very noisy with clanging sounds," "I got injured when putting back the heavy cover," and "there are no covers that fit the dimensions of the drain." With appropriate anti-corrosion treatment, it can be used for 10 to 15 years. Experience the warmth and texture of natural materials. Your awareness of the environment will also change. 【Features】 ■ Lightweight ■ Durable ■ Custom sizes ■ Anti-corrosion treatment ■ Long lifespan *For more details, please refer to the catalog or feel free to contact us.

The "Log-based Ground Reinforcement Method" is a ground reinforcement technique that supports structures by smoothly transmitting loads to the ground through log piles, and it is expected to further utilize local materials. The embedded log piles are recognized for their soundness and high reliability, and they can be machined to have beveled heads, which helps reduce head damage. Consuming log piles for ground reinforcement contributes to the formation of a "forest underground," which is linked to vibrant local forestry. 【Features】 ■ Measures against weak ground ■ Liquefaction prevention measures ■ High reliability ■ Beveled head processing ■ Improved construction efficiency For more details, please refer to the catalog or feel free to contact us.

Until now, our mission has been to protect the safety of pedestrians and workers at construction sites. We have been carefully and solidly crafting wooden products, and we have been making efforts to utilize our accumulated experience in our products. New demands that exceed our imagination are rising in public facilities such as stores, ski resorts, crowded gathering places, museums, libraries, aquariums, and spaces like parking lots and bicycle parking areas where separation from pedestrians is necessary. Our cedar thinning wood barricade has evolved (2.0) from a protective barricade to a visible barricade. 【Features】 ○ Foldable and compact storage ○ Opening stop processing ○ Paint colors can be selected ● For other functions and details, please download the catalog.

This is a cedar tree over 60 years old, grown in a region known for its heavy snowfall unique to snow country. Its base is bent due to the glide of the snow, and each shape has its own characteristics. However, it has been left behind as a building material where efficiency is prioritized. Therefore, we have breathed new life into this simple and difficult-to-express material by creating the "Snow-Bent Bench." Once you sit on it, you can feel the refined texture and gentle touch that the snow-bent cedar inherently possesses.
