About This Blog

🎯 Purpose

Kurashi Stat is an independent data blog that makes statistics about everyday life in Japan easier to understand. We organize and explain publicly available data on income, wages, household finances, population, and regional trends, with a particular focus on Tokyo and the surrounding Kanto region. Kurashi Stat is independently operated and is not affiliated with the Japanese government.

Rather than just listing numbers, we focus on how each data point actually relates to decisions people make about work and life.

For example, we look at questions like:

• "Which areas offer an income advantage?"
• "How do differences in population trends affect quality of life?"
• "Even within the Kanto region, how much do prefectures and cities really differ?"

We organize and compare these themes using official statistics as the foundation.

👤 About the Operator

This blog is written and managed by the operator of HDDH, a sole proprietorship based in Kanagawa, Japan. In our main line of work, we support small and medium-sized businesses with web development, social media operations, workflow automation tools, and AI adoption — helping clients clarify goals, form hypotheses, verify data, and propose improvements. We place importance on checking numbers and structure rather than relying on impressions alone when making decisions.

On this blog, we try to read publicly available primary-source data as accurately as possible and organize it into a form that's useful for real decisions about work and life. Where possible, the analysis note at the end of each article states the statistics used, the target year, the aggregation conditions, and a link to the original data.

💡 What We Value on This Blog

Kurashi Stat doesn't just present numbers — we aim to organize them in a way that's easy to compare and useful for decision-making. We focus especially on themes that directly affect daily life: income, wages, population, households, and cost of living.

We try to keep the following in mind when writing articles:

1. Base everything on primary-source data.
   The data we cover mainly comes from e-Stat (Japan's official statistics portal) and public statistics from ministries such as the Ministry of Internal Affairs and Communications and the Ministry of Health, Labour and Welfare. Where possible, we list the statistical table ID and a link to the original data at the end of each article.
2. Separate fact from interpretation as clearly as possible.
   We try not to blur the line between what a statistical table directly shows and our own interpretation based on regional context. Interpretive sections should be read as background reasoning, not as definitive claims.
3. Prioritize clarity.
   We avoid jargon where we can and use charts and comparisons so the content is approachable even for readers who aren't used to working with numbers.

📖 How to Read Our Articles

In addition to what the statistics directly show, our articles sometimes include supplementary interpretation based on regional industry structure, commuting patterns, population makeup, and living conditions. These interpretations are not facts that can be directly proven from the official statistics — they are our own reading, meant to aid understanding.

For that reason, if you're using this information for an important decision — a move, a job change, relocation, an investment, and so on — please also check the original data and information from the relevant public institutions.

📊 Main Data Sources

This blog mainly references the following official data sources:

• e-Stat (Portal Site of Official Statistics of Japan)
• Population Census
• National Survey of Family Income, Consumption and Wealth
• Family Income and Expenditure Survey
• Basic Survey on Wage Structure
• and others

🙋 Who This Blog Is For

This blog is written for:

• Readers who want to understand income and wage differences by region
• Readers who want to see regional characteristics through population and household data
• Readers who want statistics that go a bit deeper than the news, but without the difficulty of an academic paper

Official statistics are reliable, but the tables themselves are often too detailed and difficult for a general audience to use as-is. Kurashi Stat aims to be the bridge between the two.
