Source-derived summary

Chikashi Koizumi (古泉 千樫 Koizumi Chikashi; 1886–1927) was a Japanese tanka poet. After initially working as a primary school teacher in his native Chiba Prefecture, he moved to Tokyo and became a full-time poet. He published in several prestigious poetry magazines, even helping to found both Araragi and Nikkō, before setting up his own poetic society, the Aogaki-kai, and taking on disciples. He died before the society's organ could see print.

Editorial summary

This brief starts where responsible research should: with the source description of “Chikashi Koizumi” as japanese poet and writer. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA useful biographical orientation record, particularly for establishing names, roles and a first chronology. The current lead gives the account dated anchors—1886, 1927, 1908—that can be checked directly. The linked authority record independently contributes the date 1886-09-26. The account is most persuasive where Chikashi, Koizumi and Japanese can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the people & ideas register because the source frames it as japanese poet and writer. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Aug 23, 2026. The linked authority identifier is Q1281035. VIAF identifies the subject as 8771924. The Library of Congress control number is n83224380. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1886, 1927 and 1908.

Critical limits

Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. 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

Read biographical claims against dates, named institutions and the cited references. Distinguish a subject’s later reputation from evidence produced during their lifetime.
