AI-enabled, source-backed database for Japan's long-tail municipalities.
Hidden Japan Cities builds structured, source-backed profiles of Japan's long-tail municipalities — towns and small cities over 10,000 people, plus selected sub-10,000 high-signal towns — from a Japanese master DB where each claim is tied to an official or semi-official source, not general knowledge. It covers what human-edited travel media rationally skips.
Tourism is one application layer, not the core: the same DB is built to power multilingual content, comparisons, and structured local intelligence. The town pages below are sample outputs, not the whole product. We are deliberately assembling the source-backed text base before securing any images.
Sample tourism outputs derived from the municipality database (minimum / deep pilot DBs) — one application layer, not the whole product. Ordered by entry strength for a first-time reader. Links point to the Japanese base draft and its English localization.
A warehouse town born from Edo’s fire defenses, walkable as one route — about 30 minutes by train from Tokyo.
Kura-zukuri storehouses, the Bell of Time and Candy Alley sit within walking distance. Snack on sweet-potato treats, stroll in a rented kimono. Where Mashiko is “see → buy → make,” Kawagoe is “walk → snack → dress up → photograph.”
The same Tone River water becomes spring rapids, summer river play, and hot springs.
Season and stamina decide your axis — onsen, whitewater, or mountain. A cluster of hot-spring areas along the Tone gorge, reachable from the Tokyo area. The trip begins with “which bath.”
A pottery town where “see → buy → make” fits into a walkable half-day along one street.
Mashiko ware was started by a potter trained in neighboring Kasama. Living National Treasure Shoji Hamada’s reference museum and climbing kiln remain. A direct bus runs from Akihabara. A minimum-DB pilot that still reached a strong prototype.
The town Hokusai visited near the age of 90, leaving a phoenix on the ceiling of Ganshoin.
A dense story in a small town: the painter’s late-life ceiling work, and chestnut sweets. Strong on narrative; its one detail — the phoenix — is photography-restricted, so hero imagery is the main hurdle.
Kasama ware — a source of the Mashiko lineage — and the Himatsuri, a town where pottery is bought from its maker.
A “working pottery town”: buy directly from around 200 makers at a fair that grew from 36 backyard kilns. Also known for chestnuts. The craft baseline of the first five.
Volatile details (event dates, fees, travel times) are re-checked at publication; several categories (lodging, local transport) remain open.
