According to the latest stats released but the Welfare Ministry, the number of centenarians in Japan has increased to a record 92,139, led by women, who account for 88.5 per cent of the total with the world's longest life expectancy.




 
I think the more children the women have, the longer they live. Not sure what will happen with today's child bearing women though.
 
This is really interesting, and it also points to an inevitable demographic cliff that Japan is teetering over.

Just a thought, but the people over 100 years old now were in their 20's at the end of World War 2, which means they likely survived through some seriously dire conditions. It's a bit of survivorship bias, but for these folks at least, perhaps the harsh times helped forge them into more resilient individuals. I was just listening to an interview with someone down in Okinawa who has been researching their longevity down there (I'm not sure how much Okinawa comprises the list of centenarians, but I believe they have the highest concentration in Japan), and one of the biggest factors she was talking about beyond lifestyle and diet was social connections.
 
I'm not sure how much Okinawa comprises the list of centenarians, but I believe they have the highest concentration in Japan.

According to NHK, the Top 3 are:
  1. Shimane
  2. Kochi
  3. Tottori

The bottom of the league (least on top):
  • Saitama
  • Aichi
  • Chiba

 
Wow, I hear so much about longevity in the "Blue Zone" that it's become part of Okinawa's brand.

I couldn't find a full on list to compare populations and ratios by age, but this article says okinawa is at 68 per 100k (with a total population of about 1.4m residents), which is far below Shimane's 155/100k, who has only 650k residents and a population density of 97 per square kilometer.

 
To add to Japan's record number of centenarians, figures released by the Ministry of Internal Affairs showed that those aged 80 and older represent 10 per cent of the population for the first time.




Happy Respect for the Aged Day!
 
According to the nationwide life expectancy rankings published every five years since 1965, Okinawa's ranking has fallen sharply, especially for men, leaving it near the bottom. Central prefectures like Nagano and Shiga have moved into the top ranks, while Aomori in the northeast remains at the bottom:
  • National average life expectancy in 2020
    • Men: 81.49 years
    • Women: 87.60 years
  • Men (top prefectures, 2020)
    • Shiga: 82.73 years
    • Nagano: 82.68 years
    • Nara: 82.40 years
  • Women (top prefectures, 2020)
    • Okayama: 88.29 years
    • Shiga: 88.26 years
    • Kyoto: 88.25 years
  • Regional trends
    • Okinawa: no longer in the top 10 overall; men rank near the bottom nationally.
    • Aomori: the lowest-ranked prefecture for life expectancy.
    • Nagano and Shiga have consistently high rankings in recent years.
