星置 ほしおき Hoshioki

Teine-ku, Sapporo, and Hoshino, Otaru, Ishikari and Shiribeshi regions, Hokkaidō

Ainu spellings: Soushipokke, So-us-pok-ke

Every reading proposed for the name turns on the same choice: a waterfall or a cliff as the thing the settlement lay below. Matsuura Takeshirō's report of a proper name Soushihoki meaning two waterfalls, and the Hoshibokke still written on a 1928 village map, are the two records that bear on it most directly.

Referents

  • settlement The Hoshioki district of Teine-ku, Sapporo. In the Meiji period the name covered a single settlement between Zenibako and Karukawa, later split for administrative purposes into Yamaguchi-Hoshioki, Shimoteine-Hoshioki and Zenibako-Hoshioki; the last was renamed Hoshino in 1943.
  • river The Hoshioki River, called Otarunai River in early Meiji maps. It has been the boundary between the Ishikari and Otarunai districts, and later between Sapporo and Otaru.
  • waterfall The falls on the upper Hoshioki River: Hoshioki-no-taki and Otome-no-taki. A third, Kanayama-no-taki, was found only recently.

Analyses

so-pok

ソーポク ‘below the waterfall’ received reading
  • so ‘waterfall’
  • pok ‘below, the foot of’

Proponent: 永田方正 (Nagata Hōsei)

The river sign on the Hoshioki River carries this reading beside the cliff reading. The author notes that Nagata, working in the Meiji period, cannot have read Matsuura's Saikō Ishikari nisshi, so the agreement with Matsuura's Soushihoki comes from a second line of transmission.

Confidence: low

so 'waterfall' and pok 'below' are both in the Saru dialect dictionary and the falls are on the river, so the reading is sound as far as it goes; it accounts for neither the medial -us- nor the final syllable of the local Hoshibokke.

pesh-poki

ペシポキ ‘below the cliff’ proposed
  • pesh ‘cliff’
  • poki ‘below it’

Proponent: 山田秀三 (Yamada Hidezō)

The river sign on the Hoshioki River gives this reading beside the waterfall reading. In the Saru dialect dictionary pes is the slope of the raised ground above the sand beach.

Confidence: low

The Saru dialect dictionary carries pes as a noun for the slope above the beach and poki as the possessed form of pok, and the shape is grammatical. The postpositional adverb pes 'downstream' is a separate entry. The reading passes over Matsuura's report that the name was Soushihoki and meant two waterfalls.

pes-pok-i

ペシポキ ‘the one below the cliff’ proposed
  • pes ‘cliff’
  • pok ‘below’
  • i ‘the one, the place’

Proponent: 榊原正文

The same cliff reading with a formal noun added.

Objections

  • The formal noun i 'place' attaches to verbs, not to nouns. pok 'below' is a noun, so pok-i 'the place below' cannot be formed. pok-ke gives the same sense with no grammatical difficulty. — zenibako_trek zenibako_trek…
Confidence: low

The grammatical objection to i after a noun applies here and the proponent has not answered it.

pon-so-poki

ポショポキ ‘below the small waterfall’ proposed
  • pon ‘be small’
  • so ‘waterfall’
  • poki ‘below it’

Proponent: 浜田隆史

The waterfall reading with pon 'small' prefixed.

Confidence: low

Every part is a dictionary word and Matsuura does call the two falls small. The reading has to lose a whole syllable of pon to reach the recorded Hoshihoki.

ooho-suwoppo-kes

ホォソォポケ ‘the foot of the deep box’ proposed

Proponent: 『銭函郷土史 第一巻』

Confidence: low

ooho, suwop and kes are all in the Saru dialect dictionary, and 'the foot of the deep box' names no feature of the place that the source identifies.

so-us-pok-ke

ソウシポッケ ‘the place below where the falls are’ proposed
  • so ‘waterfall’
  • us ‘be there in numbers, be habitually at’
  • pok ‘below’
  • ke ‘place’

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

Built on Matsuura's Soushihoki. Matsuura glossed hoki as 'to line up'; on this reading so is 'waterfall', us 'be there in numbers', pok 'below' and ke 'place'. The author had earlier written the form as so-us-pok-i and replaced the final formal noun i with ke, since i attaches to verbs and pok is a noun. The place name Hoshibokke recorded into the early Shōwa period supplies the final syllable, and Hoshioki is the worn-down form of it.

Evidence

  • documents

    The 1928 land map of Zenibako village writes 字ホシホッケ and 字ホシボーケ beside 字星置 for the same ground, so the ke was still in local use.

  • topography

    Two falls stand on the upper Hoshioki River, Hoshioki-no-taki and Otome-no-taki; the third, Kanayama-no-taki, was found recently and is unlikely to be among Matsuura's two. us 'be there in numbers' points to more than one fall in any case.

  • documents

    Nagata Hōsei's so-pok reaches nearly the same reading from an independent line of transmission.

Confidence: low

The segmentation is grammatical and the reading accounts for the local Hoshibokke, the two falls Matsuura reports and Nagata's independent so-pok. so 'waterfall' and pok 'below' are in the Saru dialect dictionary; ke is a bound relational, absent from the dictionary's headwords. The reading rests on Matsuura's Soushihoki being the older shape of a name otherwise recorded as Hoshihoki.
