What do "Toyo" and "Sasaki" in the name "Toyo Sasaki" refer to?

Although it is now a single name, it began as two different companies^[1]. There are three facts at the roots of this brand: TOYO in Japan, founded in 1878; SASAKI, founded in 1902; and the merger of these two competitors achieved in 2002^[2][3].

The two companies joined forces in 2002^[4]. Although they were competitors facing each other in the glass market for a long time, through the merger, neither side's name was erased; instead, they were joined side by side to give birth to today's TOYO SASAKI Toyo Sasaki^[5][6]. The history of a 130-year tradition also stems from here^[7]. As the histories of the two manufacturers, who had built up long experience and technical prowess, fully merged, it carried on as a glassware brand with a deep history^[8].
