Walkability has been the focus of much attention in recent urban policy. In order to quantitatively verify the effects of walkability on local economies, residents' health, and other aspects of daily life, it is highly desirable to develop an objective walkability index covering a large geographical extent based on consistent criteria and release it in an easy-to-use format. We developed a walkability index (JPWI) of all postal code areas in Japan for public use, consisting of three neighborhood elements: population density, number of facility types, and road connectivity. The data table is available both in CSV and Microsoft Excel formats containing approximately 113,000 postcodes, coordinates of the representative point for each postcode boundary, and walkability values, with instructions for their use. For the user's convenience, the table file also includes the population density, intersection density, number of facility types within 1,000 meter buffers of the representative point. Using the postal code, a variety of social survey data in Japan can be easily combined with this objective walkability index for analysis. For more information on how to create the JPWI, see the article “Development of Japan Postcode-level Walkability Index and Examination of its Usefulness” (Quarterly Journal of Geography 75: 16-26).

Title (in Japanese)


Description (in Japanese)

近年の都市政策では,ウォーカビリティ(徒歩での生活しやすさ)が注目を集めている。それが地域経済や住民の健康など生活にもたらす効果を定量的に検証するには,一貫した基準による,広域的な,利用しやすい形式の指標の整備と公開が必要である。そこで,人口密度,施設種類数,道路接続性の3要素からなる,日本全国の郵便番号界ウォーカビリティ指標(JPWI)を,公開を前提に作成した。公開データは、約11.3万件の郵便番号、各郵便番号界の代表点座標とウォーカビリティ値を格納した、csv形式とMicrosoft Excel形式のテーブルファイルと、その使用説明書である。テーブルファイルには、利用者の利便のため、各郵便番号界の代表点から1000m圏内の人口密度、交差点密度、施設種類数も含まれている。このデータを使用すれば、日本におけるさまざまな社会調査データと、客観的なウォーカビリティ指標を組み合わせて分析できる。作成方法などの詳細については、次の論文を参考にされたい。谷本 涼・埴淵知哉・中谷友樹 2023. 全国郵便番号界ウォーカビリティ指標の整備と有用性の検討. 季刊地理学 75: 16-26.
