Nippon Pulse is built by one person, the Certified Public Accountant Atlas. What got done over the past month, and what is being built next — including how priorities are set — the development process is shared openly.
Pointers like "this metric is missing" or "this calculation method would be better" feed directly into the priorities below. Please send them through the request form.

The rough outline of what is to come
Since publishing v0.1 in May 2026, the commentary articles, metrics, and sourced integration of major development plans for all 47 prefectures lined up in roughly a month. That "a solo project gets this far" comes down to one thing: Atlas himself is the heaviest user. Every day I notice what is missing while using it, and fix it by the next morning.
All prefectures
9 categories
Sourced
CPA-reviewed
From the past month, we have selected the items that hold value from a user's point of view. Every past deploy can be traced down to the individual commit in the /changelog.
With password-free email-link authentication, you can now save the areas you are interested in.
Browse roughly 164 plans — urban redevelopment, new transit, industrial attraction, and large-scale events — with sources, sorted by confidence.
All nine categories — education, healthcare, housing, safety, leisure, environment, population, and more — now have multiple metrics in place.
From a CPA viewpoint, a long-form, sourced, restrained-tone article is prepared for every one of the 47 prefectures.
We can now review anonymized page views and error counts internally (we do not collect information that identifies an individual).
High-resolution views of each prefecture from verified Wikimedia Commons images, with a lightbox and loop navigation.
We imported the major facilities from the National Land Numerical Information, laying the groundwork for a future "distance to the nearest one" display.
Based on the JMA database, you can review M5+ earthquakes across all 47 prefectures, aggregated by year.
Drag-to-resize the boundary between the map and the live cameras, 44pt touch targets, and an auto-layout that resolves a lack of vertical space.
Officially published the per-prefecture dashboard. The basics — aggregated display on the map, metric switching, and live cameras — are in place.
The timing is only a target we are working towards. We rearrange the priorities as we go, by user requests and impact.
My Map plus composite metrics (overlaying and weighting several metrics), staged expansion to the municipal level, and integration of public live cameras (MLIT / JMA).
Starting from roughly 100 designated and core cities. We introduce original metrics whose calculation has been scrutinised from a CPA viewpoint (such as a Family-Friendly Index).
Expansion of the living-infrastructure, safety, and demographic categories to every municipality, plus My Base registration and travel-time calculation (Google Maps Distance Matrix).
Life-event-driven presets for marriage, childbirth, schooling, employment, caregiving, and retirement, plus full integration of J-SHIS expected-intensity, flooding, and liquefaction risk.
B2B provision for real-estate firms, home builders, municipalities, and financial institutions; API and CSV sales of cleansed data; and the World Pulse concept (overseas expansion).
I am building this site to choose my own next house. At the same time, if it helps someone who is choosing an area the same way, nothing would mean more. Failures and successes alike, I share each one on X as it happens.
To keep this running, browsing the 47 prefectures stays permanently free, while features that save you effort — saving, comparing, alerts, export — are separated into a paid plan. The breakdown, including the neutral external links, is disclosed on the pricing page.
