How to Order

The standard Kyō-ma tatami size is:

• Length: 191 cm
• Width: 95.5 cm
• Thickness: 5.5 cm

Our pricing is based on this standard size.
(Please note that this does not apply to modular tatami or certain custom and specialty products.)

Yes.

• Smaller than the standard size:
  Custom sizing is available at no additional cost.

• Larger than the standard size:
  Pricing starts at 1.5 times the standard price, depending on the dimensions.

Please note that due to manufacturing constraints, the width cannot exceed 95.5 cm.
However, the length (191 cm) can be extended to your desired measurement.

After receiving advance payment, production typically takes approximately 1–2 months.
The exact timeframe depends on the tatami grade, quantity, and size.

Yes. About 60% of my business is re-covering tatami.

Offcouse, re-covering a tatami mat is cheaper than buying a new one, but a re-cover tatami looks like a new one.

You can choose.

〈Straw : Strong Points〉・natural ・traditional ・highly moisture absorption

〈Straw : Week Points〉・heavy @35kg ・mold problem

——————————————————————————————————-

〈Kenzai : Strong Points〉・light @14kg ・durable

〈Kenzai : Week Points〉・not traditional ・slightly harder than straw

It’s possible to choose the material and color of heri.

As for material, cotton (no additional fee) and hemp (addtional fee @ *8,000 per tatami.)

If you prefer a patterned one, it is basically made of polyester.

More about Heri

The short side of the tatami is called the “kamachi.

Simply wrapping the toko around the tatami causes the corners of the tatami to become damaged or bulged.

In the past, “kamachi boards” were sewn onto the wood, but today, thanks to advances in technology,

these boards can be sewn by machine. Traditional hand-sewn wooden kamachi are superior in appearance and quality.

You can choose material from timber, plastic. timber is available @ *40,000, plastic is free of charge.

Basically, the difference is whether we sew the edges (Heri) by hand or by machine.

There is no difference in durability or surface color (omote).

When hand made, the underside of the edge is also made of straw.

If it is machine made, it will be something like white cloth tape.

Although handmade and machinemade don’t look much different.

The difference in the materials used in these small details and in the fact that the craftsman sews each stitch according to the stitches on the omote.

Handmade is our tradition of kyoto tatami.

Even if it is machinemade, the quality of the omote remains the same.

By machine : about 40 minutes.
By hand : about 4 hours.

Japanese people started using tatami about 13 hundred years ago.

The main reason is construction costs. Wooden floors are cheaper than tatami floors. But many people feel wooden floors are cold in winter, so special tatami that cover wooden floors are popular. Traditionally, Japanese people sit on the floor at home – not on chairs – tatami are much more comfortable than hard wooden floors.

Yes, we do.
