Other Works:

Kimura has apparently also written two boys’ comics, also from Akita Shoten, under the Shounen Champion Comics (少年チャンピオンコミックス) label.  (Since there is nearly a 20-year gap between these and Unlucky Sachiko, I’m not sure it’s the same author.)

• Benimaro* (べにまろ) 1-9
• Trouble Mask* (とらぶるマスク)

His most recent works are Nippon no Waka Oku-sama (ニッポンのワカ奥さま) 1 and O-kaa-san ga Issho (おかあさんがいっしょ) 1, published by Houbunsha (芳文社) under Manga Time Comics (まんがタイムコミックス).
