Mountain Climbing

In addition, there are mountain trails on the western side of Mount Tengu from Shibunoyu, 1,880 m (6,168 ft), in Oku-Tateshina Onsen Village and from Karasawa Kosen, and on the eastern side from Inakoyu via Honzawa Onsen.

A mountain hut, Kuroyuri Hutte, 2,400 m (7,874 ft), is located at Kuroyuridaira, just west of Nakayama Pass (中山峠, Nakayamatōge), where the mountain trail from Shibunoyu joins the main traverse route.

Editorial summary

Begin with the source’s own compact description: “Mount Tengu” is mountain in Nagano Prefecture, Japan. The dossier treats that line as a proposition to test through Mount, Tengu and mountain, not as a finished interpretation.

Editorial reviewA strong orientation record where physical form, institutional use and historical geography need to be read together. The current 231-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. For this dossier, Mount, Tengu and mountain is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “mountain in Nagano Prefecture, Japan” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated May 24, 2026. The linked authority identifier is Q6924077.

Critical limits

Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.
