As others have mentioned, I also remember when 'made in Japan' meant poor quality, but of course in the '80s that began to really change. Although back in 1977, I bought a Japanese-made lockback that resembled a slimmer Buck 110 that was very good quality...it was my first lockback knife. Back in the '70s, I also owned some cheap American-made pocketknives that were junk, and would fall apart with light use. Manufacturers in every country are capable of good and poor quality.
But funny enough, 'made in Taiwan' is a much more recent stigma that only began to turn around starting in the late '90s or so. Now, of course, we can see there can be and is excellence in Taiwan manufacturing. There are some people who even continue to confuse China and Taiwan (and sometimes even including Japan!) as some monolithic manufacturing entity when they are all unique and different.
As for 'made in China', I own only about 3 Chinese-made knives...a Henckels Santoku, a Byrd hawkbill, and a Messermeister picnic knife. They work great, but I prefer Swiss, Japanese, U.S., and Taiwan-made knives. Not for any political reasons, but just because I do.
