October 27, 2026 research. Explicit elder brother of Haruji Matsue. Shared parentage is not inferred from sibling wording alone. Sources: https://jahis.law.nagoya-u.ac.jp/who/docs/who8-20515 Provisional—published historical directory transcription; original family register not inspected. Kanji retained where given-name pronunciation is unverified. This collateral Sugi–Tejima branch does not establish that the directory Ichiro Sugi was Rei’s grandfather.
