Illustration of Hirasawa Kanga Ruins, Ibaraki — Illustration — not a photograph

Hirasawa Kanga Ruins has outlasted the version of Ibaraki it was originally built for, and it shows.

In the eighth century the province of Hitachi was administered through district offices, and the one for Tsukuba district stood on this terrace below the mountain. Excavation found the postholes of a compound of raised storehouses — the granaries where the rice tax was kept — and three of them have been reconstructed full size on their original footprints, in three different construction methods: a log-built azekura, a plastered earthen store, and a plank-built one.

The effect is unusual. There is no ruin to squint at and no scale model: three large eighth-century buildings stand in an open field with Mt. Tsukuba behind them, and you can walk between them. It is free, it is almost always empty, and it makes the administrative machinery of the Nara state suddenly physical.

Historical notes & tips

**Three buildings, three methods.** The log-stacked azekura, the earthen-walled store and the plank-built one sit side by side deliberately — the point is the comparison. Walk round all three rather than photographing the first. **Check access before you go.** The city publishes the current status. **Mt. Tsukuba is the backdrop.** The buildings are aligned with the mountain behind them, which is almost certainly not an accident and is what makes the site photograph well. Late afternoon light works best. **Combine with Mt. Tsukuba itself.** The shrine at the foot and the cable car are ten minutes away, so the granaries slot naturally into a Tsukuba day rather than standing alone.
