Toyo-Sasaki, the top glass manufacturer in Japan, created the Hard Strong (HS) glass-strengthening technology in 1967. Applied to the top portion of each glass, this technology toughens and tempers the glass for durability and safety.
At the Toyo-Sasaki factory in Chiba, Japan, each glass is meticulously examined by many sets of human eyes. This helps to ensure that the glasses remain sturdy and maintains its clarity for years to come.
Testimony by an Umami Mart customer:
"I dropped a Hard Strong glass on my granite counter top, then it bounced into my steel sink and nothing happened! I saw it with my own eyes in slow motion, sure it was going to shatter during the tumble. These are truly Hard Strong!"

*This testimonial was given in March 2014, in regards to the Fluted Old Fashioned glass, which has the HS Platinum grade protection. Glassware breakage is inevitable but the extra HS coating (plus good care and a little luck) helps to prevent it when possible. Read more about the Hard Strong technology here.
