Nature drying

Air drying

The lumber that’s used for manufacturing masu cups undergoes a process of natural drying either indoors for a maximum of 4 months or outdoors for maximum of 1 month depending on both the quality, condition of the hinoki wood and the weather of the actual season as well. The goal of the drying the hinoki is to decrease the moisture content of the wood to a level that is appropriate for the manufacturing process. The gist of the process is to create a stack of the lumber on raised foundations and dry it gradually with a continuous flow of air. The loss of moisture inevitably causes the shrinkage of the hinoki wood, so it needs to be controlled with care as too rapid drying may lead to damaging the wood. If the lumber is considered dried, then it’s ready for manufacturing.

Cutting1 Cutting2

Cutting3 Cutting4

In this step, the lumber is cut into pieces of uniform size and shape by a machine that also shaves both sides of the lumber thoroughly. Each and every piece is checked for any faults like wood knots, deformations etc. and these faulty pieces are removed before sending them to the next manufacturing phase. Hinoki (Japanese Cypress) is a relatively expensive wood. Throughout the whole cutting process craftsman aim to leave as low waste as possible since they would like to offer their products on a low price and they would like to be ecologically conscious too.

Flutings1 Flutings2

After cutting the parts of the masu cups into the right sizes and shaving them nicely, the joinery work starts, finger tenons are cut into all of them for joining together all four sides of the masu cups. The cutting edge of the tenon cutter machine is polished every day for keeping it as sharp as possible, since this helps to make the quality of the masu cups especially good.

The adhesion2 The adhesion2

Frame assembly
The tenons of the sides of the masu cups are first glued with an adhesive that’s harmless to the human body after dried, and then these side pieces are placed into the frame assembly machine that presses all 4 sides together. Next the frame is checked again visually for any kinds of faults like the assembled frame being too frail, wood knots etc. and these defected pieces are removed from the production. Checking is a vital part of every production step. Concerning the safety of the adhesive used in the production, we have 2 safety certifications: one is issued by JFRL “Japan Food Research Laboratories” and the other one is issued by JCII “Japan Chemical Innovation and Inspection Institute” both documents are in Japanese. Please contact us if you would like to acquire the English versions of any of these documents.

Adjustment Adjustment2

All the surfaces of the assembled frames are leveled using a so-called “planer disk”, the machine displayed above.
In this step, Japanese craftsmen don’t need to take a look at the masu frames; they know exactly when the surfaces of the frames are perfect by the slight change in the sound of the planing. After the frames are planed, the bottom of the cups is glued to the frames to make the masu cups complete. Besides paying attention for the surfaces, the craftsmen take care to produce masu cups of uniform size. Moreover, after this process every masu cup is checked again for defects like cracks etc. and defected products are removed from the process.

Finish Finish2

Finishing touches
In this step the masu cups are briefly put into water so that the joints get a little swollen which makes the gluing hold even better and it gives the masu cups a little gloss as well. Then all four sides of the masu cups are planed once again equally to make them completely smooth using an even finer "planer disk".

Corner collecting1 Corner collecting2

Edge shaping
The goal of this process is to make the touch of the masu cups even better so anyone who uses these cups can feel good when taking them in hand. 10 pieces of masu cups are processed at once in this step; it’s yet again a good example for the expertise of the craftsmen manufacturing them. Since this is the final manufacturing process, the masu cups undergo a final, very throughout check before they are declared completely finished.

Stock Stock2

The finished wooden masu cups are stored in a cool dry place until they are shipped.

Packing Packing2 Packing3 Packing4

Right before shipping, every 5 piece of masu cups is wrapped in thin brown kraft wrapping paper and they are placed in a cardboard box. For worldwide shipments the cardboard box is then placed into an even bigger cardboard box with some cushioning materials to protect the masu cups on their way to your country.

We sincerely hope that we can deliver the warmth of traditional Japanese wooden masu cups to as many customers around the globe as possible. They don’t come empty; they are filled to the rim with the spirit of all the people who deliver them to you. Please enjoy the unique experience of MASU!
