Improving Quality in Pursuit of User Friendliness
Three years after he founded his business, Kuroda decided to take on the task of manufacturing the entire wachÅ. However, as a latecomer to an industry that was already filled with existing wachÅ makers, Kuroda's company needed to fight the odds to compete. What is more, no matter how hard he tried, his prices continued to hover at a slightly higher rate than his competitors'. He conducted a thorough survey of his competitors' products and found out that the reason for this had to do with the difference in the type of paper being used for the inner pages. In order to give the wachÅ the appearance of thickness, most companies were using coarsely made, low-quality paper with a rough surface. This was a time when the main writing tool was quickly changing over from the brush to the pen, and this type of rough paper was proving to be difficult to write on with a pen, as its nib would get caught in the fibers. To deal with this issue, Kuroda pleaded with and convinced a paper company to make a completey separate batch of firmer, heavier weight paper that had a smoother surface texture.

Originality and Wholeheartedness
Another common flaw of the wachÅ was the inconvenient tendency for its last few pages to start rolling back at the corners after some use. To remedy this issue, Kuroda attached sturdy pieces of handmade support paper on both sides of the inner pages. Also, while other wachÅ pads claimed to contain 100 pages but were often actually a few pages short, Kuroda insisted that each of his company's pads contain exactly 100 pages, and added an inscription of "shÅ hyaku mai" (meaning "exactly 100 sheets") on the cover. These factors, it was found, were what caused the price of Kuroda's wachÅ pads to be slightly higher than his competitors'. But Kuroda, who had incorporated these innovations to offer more ease of use to the customers, insisted on moving forward with these products as they were, for the last thing he wanted to do was to provide anything of inconvenience to his customers.
