The Japanese eyewear industry is on the verge of a significant shake-up, with a transition towards a "big three" oligopoly system looming. Recent consolidations and strategic alliances within the sector suggest the emergence of three dominant companies, a move primarily aimed at market sustainability. While it is unclear when this shift will take full effect, these changes herald a potential reshaping of Japan's competitive glasses market.

In Japan, the glasses industry plays a significant role in the lifestyle of its populace due to the nation’s high prevalence of myopia. The expected restructuring is likely to impact consumer choice and possibly prices. Japan's business culture respects healthy competition; hence, this shift will be observed closely for its implications on market diversity and consumer satisfaction.

In contrast, the U.S. or E.U. eyewear markets are already dominated by a few major players. Market consolidation and dominance by big brands isn't as much a newformation as in Japan, rather a continuing trend.
