Lake Shikotsu and Chitose, Ishikari region, Hokkaidō

支笏

しこつ Shikotsu

The received reading and the author's differ in one consonant and in what the name first denoted: the lowland around Chitose, or Lake Shikotsu in the mountains. Both parties read the second element as kot 'hollow'. The Edo-period informants tie the name to Shikotsu-yama, which the sightline reports identify as Mt. Fuppushi.

Ainu spellings: Sikot, Sikkot

Analyses

si-kot

シコッ

received reading

big hollow

  • si big
  • kot hollow, valley

Proponent: 山田秀三 (Yamada Hidezō)

Yamada writes in Hokkaidō no Kawa no Na that the ground above the town of Chitose forms a large hollow around the Chitose River, a valley in English, that it was a famous fishing place, and that it was therefore called Shi-kot and used as both a river name and a place name. Hokkaidō Ekimei no Kigen gives the same reading and takes the name to have covered the whole lowland between Sapporo and Tomakomai. Osatsu-numa and Maoi-numa, shallow and wide, lay in that lowland, and the watershed at the present airport stands only about 25 m above sea level.

Objections

  • The elders put the accent on the first syllable, シコツ, where si-kot would put it on ko. si carries the sense 'true' or 'main', which the gloss 'big' does not match. The Edo-period accounts collected from the Shikotsu Ainu also reverse the order of naming: the district takes its name from the mountain and the lake. — zenibako_trek zenibako_trek2024

Analysis details
Confidence: low

kot 'hollow' is a dictionary word in the sense used and the Ishikari lowland fits it; the accent and the first element carry the doubt.

sik-kot

シコッ

proposed

hollow filled with water

  • sik be full of water
  • kot hollow, valley

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

The name is taken to belong to Lake Shikotsu. kot names a valley or a hollow and is seldom used of a pond or a lake, which is what the author's sik 'be full of water' is meant to answer for. The reading matches the elders' accent on the first syllable.

Variants

  • sik-kot-toho ‘lake of the water-filled hollow’ — The shape the author gives for the lake, after the spelling シコツトホ; toho is the possessive form of to 'lake', and to serves as well.

Evidence

  • morphological pattern

    The elders pronounced the name with the accent on the first syllable. The article states that the difference of accent between the two readings of Shikotsu is noted in Tamura's dictionary.

  • documents

    Tōyama Kinshirō (1807), Tamamushi Sadayū (1857) and Matsuura Takeshirō (1846) all record that the river is called Shikotsu because it comes from Shikotsu-yama, and Matsuura adds Shikotsu-numa. Reports of sightlines from Koitoi, Shikiu, Izaributo, Naganuma, Tōbetsubuto and the upper Yūfutsu, and the statement that the ridge of Tarumae runs on into Shikotsu-yama, place Shikotsu-yama at Mt. Fuppushi, which juts far into the lake.

Analysis details
Confidence: low

Both parts are dictionary words in the senses used, and the reading agrees with the reported accent and with the Edo-period accounts that name the lake first. The support for sik over si comes from an accent report, since the two are said to sound almost alike and no spelling separates them.

Shikot-to

proposed

Rushes lake

  • Shik rush
  • ot plural marker
  • to lake

Proponent: John Batchelor

Ot determines the shik, a rush, to be of the plural number.

Confidence: low

Batchelor's reading and gloss as printed in 1905; the segmentation is his, and several of its elements answer to no dictionary headword.

    The Edo-period accounts collected from the Shikotsu Ainu put the naming the other way round from the received explanation: the district is called Shikotsu because the river comes from Shikotsu-yama and Shikotsu-numa.

Related names

  • シコテㇺコ・エアン・パラト — A name for the lake reported by Yamada Hidezō. The author reads it sik-kot-emko-e-an-para-to 'the wide lake in the middle course of the Shikotsu River' and adds that emko means 'middle', so whether a lake at the head of the river is meant is unclear, unless the Bifue River above the lake counted as the Shikotsu River too. zenibako_trek2024
  • オコタンペ — A name north-west of Lake Shikotsu, read o-kotan-un-pe 'place with a settlement at its mouth'. The author places the old Shikotsu settlement around the former Okotan campsite. zenibako_trek2024
  • 江別 えべつ — The author derives it from the Chitose stretch, ipe-ot-i 'place where there are many salmon', and observes that the name now sits at Ebetsubuto where the Ebetsu River meets the Ishikari, a shift toward the river mouth of the kind Sapporo also shows. zenibako_trek2024
