As a domain expert in demography and social statistics, I have a keen interest in the study of population dynamics, including the number of centenarians in different countries. When it comes to Japan, it is well-known for having one of the highest life expectancies in the world, which naturally leads to a significant number of individuals reaching the age of 100 or more. Let's delve into the topic with a detailed analysis.

**Step 1: Understanding the Context and Data Sources**

The first step in addressing this question is to understand the context and identify reliable data sources. The information provided suggests that as of September 18, 2016, there were more than 65,000 people in Japan who have lived for 100 years or more. This figure is significant and reflects the country's advanced healthcare system, social welfare, and lifestyle choices that contribute to longevity.

It's important to note that population statistics are dynamic and change over time due to various factors such as birth rates, death rates, and migration. Therefore, the number of centenarians can fluctuate. The reference to the United States having roughly 10,000 more centenarians, despite having a larger population, is also a point of interest. This comparison underscores the fact that Japan has a higher proportion of centenarians relative to its total population.

**Step 2: Analyzing the Factors Contributing to Longevity in Japan**

Japan's high number of centenarians can be attributed to several factors. The country's healthcare system is one of the most advanced in the world, providing comprehensive care to its citizens. Additionally, the traditional Japanese diet, which is rich in fish, vegetables, and whole grains, is known for its health benefits and is linked to a lower risk of chronic diseases.

Social factors also play a role. The sense of community and intergenerational support in Japan can contribute to the well-being of the elderly. Moreover, the cultural emphasis on physical activity and mental stimulation can help maintain the health and cognitive function of older adults.

**Step 3: Considering the Impact of Demographic Trends**

Demographic trends are crucial when discussing the number of centenarians. Japan, like many developed countries, is experiencing an aging population. This demographic shift has implications for the country's economy, social services, and healthcare system. As the population ages, the number of centenarians is likely to increase, barring any significant changes in mortality rates.

Step 4: Current and Projected Numbers

While the figure provided is from 2016, it's essential to consider more current data to provide an accurate answer to the question. As of my last update, I do not have access to real-time databases or the ability to perform live searches. However, it is reasonable to assume that the number of centenarians in Japan has continued to rise, given the country's ongoing commitment to healthcare and the well-being of its elderly population.

Step 5: Conclusion

In conclusion, Japan's high number of centenarians is a testament to its healthcare system, diet, and social structures that promote longevity. While the exact current number may not be available without access to the latest databases, it is clear that Japan has a significant and growing population of individuals who have reached the age of 100 or more.
