How millions of tatami mats are made from grass in Japan - Amazing Japanese mat making techniques

How does ordinary green grass become one of the most expensive, best-smelling floors in the world? It takes a strict one-to-hour transformation involving ovens, clay, mud, baths, and insane human precision. Let's look inside the hidden factories of Japan to see how tatami mats are perfected. Next, when November arrives, a mechanical transplanter drives smoothly through the watery, muddy fields to plant the green seedlings. This heavy machinery operates with incredible precision, aligning every single plant into perfectly straight rows that look like a living green grid. Stick around to see how this incredibly messy mud field eventually transforms into a luxury premium floor later. Since no machine is perfect, farmers wade through the thick mud to manually fill in any empty spaces left behind. This human backup crew ensures that no patch of soil is left lonely. When spring arrives in April, the warm weather makes the grass grow super tall and lanky. Workers roll in with a specialized machine to give the entire field a perfectly flat haircut, ensuring every single strand grows at the exact same pace. But why build a giant grid of strings and nets over the crop? This clever structural network acts like a protective cage, supporting the heavy plants and keeping them from falling over or turning into a tangled mess during windy storms. Then, during harvest time in late June, a specialized harvester smoothly cuts down the massive waves of green grass, bundling them up to be transported by a handy forklift. Right after that, the freshly cut grass bundles undergo a thorough wash under a multi-nozzle sprinkler system. This high-pressure shower removes all dirt and field debris in seconds. Keep watching because a bizarre mud treatment is coming up next. Next, workers submerge the grass bins into a specialized clay mud bath. This weird muddy step looks like a disaster, but it naturally shields the fibers and traps the iconic aroma inside. Following that, the mud-dyed grass travels into giant curing ovens to dry completely. Removing all hidden moisture turns the fragile straws into tough professional crafting materials. Once the grass is fully dry, workers sort through the straw to brush away dust and slice off any uneven tips. Only the finest, highly qualified fibers are chosen to graduate to the weaving stage. Don't skip because the industrial magic in the next step is highly satisfying. A massive automatic weaving machine locks the premium grass fibers into a tight uniform pattern. This heavy industrial loom quickly manufactures a smooth and beautiful mat surface. An experienced craftsman uses sharp tools to trim the excess edges of the newly woven mat. This meticulous inspection ensures that every single centimeter is perfectly uniform. Think weaving the surface is hard. Wait until you see the hidden layer coming up next. To start the core, workers stack organic, pesticide-free rice straw alternately by hand. This careful stacking process naturally creates a perfectly flat and structurally balanced base. Now we are entering the final assembly phase. Watch how it all comes together perfectly. The craftsman guides the layered mat through a specialized sewing machine to attach the grass cover. Strong mechanical needles bind the green surface securely to the heavy straw core. Right after that, an automated system wraps and sews traditional decorative fabric borders along the edges. This engineering precision creates beautiful clean lines on both sides. To finish the look, workers flip the mat to secure the corners and attach borders on the remaining sides. A quick industrial clean removes any loose fibers before stacking. Finally, the expert installer fits the heavy tatami mats into the room like giant puzzle pieces. A final traditional sweep leaves the custom floor spotless and ready for everyday comfort.
