Mount Kamuriki
mountain peak in Japan
Mount Kamurigi (冠着山, Kamuriki-san) is a 1,252 m (4,108 ft) mountain peak on the border of the city of Chikuma and the village of Chikuhoku in Nagano Prefecture in the Chūbu region of Japan. It is also called Ubasuteyama or Obasuteyama (姨捨山) after an old legend. the mountain is located within the borders of the Yatsugatake-Chūshin Kōgen Quasi-National Park.
Geography
Mount Kamuriki is southwest of the Nagano Basin and is a Quaternary intrusion into the central uplift zone and western sedimentary zone of northern Fossa Magna where the sandstone, conglomerate and tuff deposits of the Tertiary strata were deposited during the time the area was ocean floor. The summit is a bipyrite andesite eroded lava dome, and although no direct evidence of volcanic activity exists, columnar joints can be observed on the rock on the eastern slope of the summit. A large portion of the summit collapsed during the 1847 Nagano earthquake.
Ubasuteyama legend
The mountain is strongly associated with the Ubasuteyama legend, which is mentioned in the Kokin Wakashū poetry anthology of 905 AD, indicating that the legend itself was much older. Per Japanese folklore, the pre-modern Japanese practiced senicide, whereby an infirm or elderly relative who were a burden on the community were taken to a remote, desolate place, and left there to die. The identification of Mount Kamuriki as this location appears to be from legends in the Yamato Monogatari (951 AD), the Sarashina Nikki (1059 AD), and the Konjaku Monogatarishū, (c.1120 AD) among others. The mountain has a landform (the Bokodaki Iwa), which resembles a person carrying another person on his back up the mountain.

Why this record matters
The phrase “mountain peak in 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.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Aug 15, 2026. The linked authority identifier is Q17351659. Authority coordinates are 36.281, 138.062. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1847, 1059 and 1120.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
