Introducing convenient Mahjong tools from China, the birthplace of Mahjong.
This product is for fully automatic Mahjong tables and utilizes the rattling noise during shuffling to automatically clean the tiles, making tile washing easy.
Shuffling, cleaning, and stacking are automated, allowing you to enjoy a stress-free game up to a half-jo.

Made from fluffy material similar to cotton.
The yellow ball is the cleaning ball.
The white ball is a ball that absorbs and wipes off dirt floated by the yellow ball.
Depending on usage frequency, the effect lasts about one month per set.
Our company offers two types of products: one for one month and one for two months.
We also provide a standard set and a thorough cleaning set, allowing you to choose from four different products.

By placing the product inside the fully automatic table and mixing it with the rattling noise during shuffling, friction causes the yellow ball to lift dirt from the tiles, and the white ball wipes off the floating dirt simultaneously.

Using this product provides three major effects.
Tile cleaning, sterilization and disinfection, and reduction of noise during automatic shuffling, including lowering the unpleasant metallic sound.


The significant cultural difference between China and Japan in Mahjong usage led to difficulty in using the product, but choosing the smallest size alleviated this issue.


A major problem when introducing this product to Japan was the difference in tile sizes.
This is due to cultural differences in Mahjong.
The most common difference is in tile size.
This product was developed mainly for cleaning larger tiles common in China, so the size of the balls is also large, making it difficult to use with standard 26mm Japanese fully automatic Mahjong tables.


We adopted the smallest size, choosing a diameter of 6mm.
Although the size may still cause issues, you can cut the balls with scissors to make them smaller or pinch and trim them to your liking.
The material is easy to modify, which is one of the advantages of this product.


We paid particular attention to the ratio of cleaning balls, with more white balls to ensure dirt lifted by floating is not missed, along with the cleaning (yellow) and adsorption (white) balls.
The standard type (9 balls) has 3 yellow and 6 white balls; the thorough type (12 balls) has 4 yellow and 8 white balls.
Verification revealed that the white balls, which absorb and wipe off dirt lifted from the tiles, were insufficient in number.
All our products use a higher ratio of adsorption balls at 1:2.
They clean thoroughly in a short time.
*From early October 2020, the product will be gradually upgraded to an improved version.
Please be aware of this.


To enable safer play... For Mahjong enthusiasts who love the game, and also for commercial use in Mahjong parlors, rooms, and shops, please make use of this product.

[Caution] We are not responsible for any accidents or damages caused by using this product.
Please understand in advance.
Instruction manuals and warranty cards are not included.
This product is intended solely for cleaning tiles during intense games like East Wind or Half-Jo, to reduce dirt during play without interrupting the game, so we ask for your understanding.
Please continue to perform daily maintenance and cleaning of the table and tiles as usual.

Because of these times, we want to enjoy Mahjong hygienically and safely.
In response to your expectations, we introduce a cleaning ball exclusively for fully automatic Mahjong tables.
Yellow and white balls.
The yellow ball lifts dirt such as fingerprints, sebum, and grease, which is then caught by the white ball.
The secret is simply placing the balls inside the automatic table.
Using the rotation of the rattling during shuffling, the yellow ball spins with the tiles to lift grease, dirt, and fingerprints, while the white ball catches and stacks the dirt in a clean state on the table.
It also helps reduce mechanical noise during shuffling.
During the rotation of the rattling, it contributes to cleaning the tiles, cleaning inside the machine, and lowering operational noise.

The effect lasts approximately 1 to 2 months per set.
When the entire ball turns black and becomes stiff and dirty, it is time to replace it.
Since they cannot be washed and reused, remove all balls from the table and dispose of them as combustible waste.

For those familiar with the manga, try the famous Gun Tiles and Gun Attachment.
While many cheating methods exist in Mahjong, such as intentionally marking certain tiles with fingerprints for identification, these can be cleaned during shuffling, so they may also help prevent cheating with Gun Tiles.
Please do not misunderstand; daily maintenance and cleaning of the table and tiles should be performed as usual before each game.
This product is designed to clean tiles during intense games like East Wind or Half-Jo, to reduce dirt without interrupting play, so we ask for your understanding.

Set contents: cleaning balls (yellow) x3, adsorption balls (white) x6, as one set, approximately two months' supply. Size (approx.): 6cm (if too large, you may cut with scissors to make it smaller).
We welcome Mahjong parlors and shops as customers.

＊Please do not exchange the balls during shuffling, as it is dangerous.
Partial replacement of only specific dirty balls reduces effectiveness; when replacing, replace all balls at once.
Please periodically check that the table is functioning properly.
Specifications and designs may vary slightly depending on the time of arrival and lot.
Please understand in advance.
Due to display and environment, there may be slight differences in color and appearance from the images.
Thank you for your understanding.
