Analyses

ya-o-i

ヤオイ ‘the thing that is widely attached to the shore’ proposed
  • ya ‘shore, land’
  • o ‘be there in quantity, be widely attached’
  • i ‘the thing that’

Proponent: 榊原正文

The reef off Yaoi-zaki is well developed and makes a landform of its own, which the reading takes as the referent.

Objections

  • A reef would call for kapar-sirar 'flat reef'; ya 'land' sits oddly here, and no other place name of this shape is known. — zenibako_trek zenibako_trek…
Confidence: low

The segmentation is straightforward, and the objection is that the vocabulary does not fit a reef and the pattern has no parallel.

ya-o-i

ヤオイ ‘place where the nets are’ proposed
  • ya ‘net’
  • o ‘be there’
  • i ‘place where’

Proponent: zenibako_trek(小樽銭函地名歴史研究会) (zenibako_trek (Otaru Zenibako Place-Name and History Society))

Taking ya as 'net' gives roughly 'fishing ground'. Fishing huts stood at Yaoi from long ago, and there was a landing place there.

Evidence

  • parallel place names

    Names of the type ya-us-i 'place where nets are' occur all over Hokkaidō.

    • ヤウシ ya-us-i
      • ya ‘net’
      • us ‘be attached at’
      • i ‘place where’
Confidence: low

Tamura carries ya both as a net and as land, so the reading turns on which of the two is meant; the choice rests on the parallel names and on what stood at the place.
