Read this in parallel with Shiki's haiku collection, but Ishikawa's tanka win the day by a huge margin for me. He is a master of portraying these tiniest/subtlest moments from everyday life that are full of wabi-sabi, leaving you a bit sad, a bit empty, and a bit more aware of life around you. The longer form of tanka compared to haiku—bigger canvas—might limit/define what each form can do, but I very much appreciate what Ishikawa's tanka do over Shiki's haiku informed by the literary naturalism of 18th century France. Definitely a fan.
