Yokohama Shopping Log is for me the best slice-of-life series out there. Ashinano is an incredible artist who excels at evoking melancholic feelings through his art. His use of shadows and light is my absolute favorite. I hope many will try this manga out, now that it's licensed.
Just from the chapters I read, the main character goes through such a great development, I really hope it can gain the same kind of traction as in Japan.
