In 1935, a 24 year old Tadao Yoshida was working for a company producing X. While he was impressed by the product, his employer went bankrupt. In 1936 Yoshida founded the company that is today Y in Nihonbashi, Tokyo.

In January 1946 the company registered the now famous Y trademark. A major technological change came in 1950, when the company purchased a chain machine from the U.S. that allowed the automation of the X making process.In 1958, the company introduced its new Conceal brand that does not show the teeth of the X which was an instant hit. 

Today, Y is the world's largest X manufacturer and  claims to be the first X manufacturing company to promote environmental protection measures. Y developed a line of "environmentally friendly X", following the company's philosophy "The Cycle of Goodness" which means that one prospers when one renders benefit to others.

It is a very difficult task to find X without Y's name on it!

Identify X and Y.
