China, Taiwan, Japan and Korea had very similar growth trajectories in GDP per capita from around $1000 to $11000
Japan went from 1058 in 1966 to 11584 in 1985 (19 years)
Taiwan went from 1158 in 1976 to 11242 in 1993 (17 years)
South Korea went from 1055 in 1977 to 11561 in 2001 (24 years, a little slower due to 1997 crash)
China went from 1053 in 2001 to 11819 in 2021 (20 years)
What's incredible is the fact that China is like 5 times larger than the rest of them combined
This is not an apples to applies comparison
- inflation rates were much higher between 1970-1990
- each economy achieved >$10000 USD per capita in different years when the USD had very different values. Specifically, $100 US dollars in 1985 in the case of Japan was worth more than $100 US dollars in 2021 in the case of China.

Adjusted Figures for Inflation >> (assuming your per capita figures are correct)
Japan: 11584 / 3.4173071162 =
$3389.80 >> increased from $1058 USD$ (1965) to $3389.80 USD$ (1985)
Taiwan: 11242 / 2.68467113758 =
$4187.48 >> increased from $1158 USD$ (1975) to $4187.48 USD$ (1993)
S.Korea: 11561 / 3.11255487677 =
$3714.31 >> increased from $1055 USD$ (1976) to $3714.31 USD$ (2001)
China: 11819 / 1.55560179362 =
$7597.70 >> increased from $1053 USD$ (2000) to $7597.70 USD$ (2021)
When you adjust for the depreciation of the US dollar over the time periods you used, China's growth from >$1050 US dollars to >$11000 US dollars wiped the floor against Japan, Taiwan and S.Korea. It's not even remotely close. However, even though this comparison is less flawed, it's STILL flawed. A baseline year using constant US dollars that all 4 economies could be compared against needs to be used. In this comparison, it would need to use 1965 constant US dollars since Japan has the earliest baseline year where we measured growth at 1966. Even then, this ignores fluctuating currency rates which can be overvalued or undervalued despite whatever the market value moved that currency or whether economies enforced currency pegs like what was going on with all of these economies at some time.
The best way to measure and compare these economies is to use constant US dollars of 1965 using PPP, not nominal rates. Despite it looking like China comes out the clear winner here after adjusting for inflation, aka. US dollar depreciation, it is a fact that the S.Korean Won was very overvalued in 1975 at around 500 to 1 USD$ whereas it stands at around 1175 today. I don't have stats for PPP since this wasn't used until 20 odd years ago. However, we do know the discrepancy today between the nominal GDP per capita in S.Korea is somewhere between 1.25-1.35 and for China somewhere between 1.7-1.9. If we apply these ratios of PPP to nominal GDP, then China marginally beats S.Korea with Taiwan following and finally Japan. This is a fun exercise but we should keep in mind that Japan, S.Korea and Taiwan were propped up with favorable policies by the US for decades and those policies continue to this day for S.Korea and Taiwan. Japan was doing gangbusters until they became too big for their britches in the late 1980s and we all know about the lost decades since then.
- differing currency exchange rates between the time periods you used for each economy skew the comparison
