Japanese Plastic Shikiita Brands: A Buyer's Guide to Resin Ground Mats

The resin shikiita brands Japanese sites specify most often — Super Ju-Lite, Repi Board, W-Board, Koujiban and Tough Mat — what each is known for, and where a factory-direct HDPE mat fits alongside them.

A market with its own vocabulary

Japan buys plastic ground mats under names that do not translate directly. The product is a shikiita (敷板) — literally a laying board — and the plastic version is often shortened on site to purashiki (プラシキ). Panels are specified in traditional shaku sizes rather than metric round numbers, so a 3×6 board means 910×1820 mm and a 4×8 board means 1219×2438 mm. That vocabulary matters when comparing suppliers, because a Japanese rental catalogue and an overseas manufacturer's spec sheet can describe the same panel in numbers that look nothing alike — the shikiita sizes and prices guide works through the conversions.

Super Ju-Lite

Super Ju-Lite, from Keiyo Kogyo, is one of the names that comes up first in Japanese resin shikiita procurement. It is generally specified as a lightweight resin board for site access and temporary roadways, sold in the standard 3×6 and 4×8 footprints with variants aimed at different traffic weights. Its position in the market is largely built on being a familiar, widely-handled product that rental yards and contractors already know how to quote.

Repi Board and W-Board

Repi Board, associated with Hoshin, is another resin board specified for repeated site use, and is typically found in the same size range as other domestic panels. W-Board, from Wood Plastic Technology, sits slightly apart: it is a wood-plastic composite rather than a straight resin moulding, which gives it a different weight and stiffness profile from a purely plastic board. Buyers comparing the two usually end up weighing handling weight against rigidity under a concentrated load, which is the same trade-off that decides between plastic and timber matting anywhere else.

Koujiban and Tough Mat

Koujiban (こうじばん) is used both as a product name and, loosely, as a category term for reinforced plastic site boards, so it is worth confirming exactly which panel a quotation refers to. Tough Mat is likewise specified for heavier-traffic site access. Across all of these, the published information tends to describe intended use and panel format rather than a standardised bearing figure, so like-for-like comparison usually means going back to thickness, material, and the load actually crossing the panel rather than trusting a product name to imply a capacity.

Where a factory-direct HDPE mat fits

Domestic brands are the straightforward choice when a site needs a handful of boards next week — the stock is local, the rental channel is established, and there is no import lead time to plan around. Factory-direct import becomes worth pricing at a different scale: when a contractor or rental fleet is buying panels by the container rather than by the pallet, when a specific thickness, colour, or moulded logo is wanted, or when the same specification will be reordered over several years. Our standard HDPE ground protection mats ship in the 4×8 ft format that maps onto the Japanese 4×8 board, with heavier sections available for plant traffic. The honest trade-off is lead time and minimum order quantity against unit cost, and it only favours import above a certain volume — tell us the panel size and annual quantity and the comparison is easy to run before committing.
