“I have been try so hard to figure out what this cute, fuzzy little guy is called..but I can’t find anything. Found him in Yokohama-shi!”

I am reasonably certain that your fuzzy flat caterpillar is a type of 

Lappet Moth 

that are often found on pine trees in Japan. They’re known as 

カレハ蛾 “Kareha-ga" 

moths in Japanese.  I couldn’t find one with that particular coloration on the page of Lappet Moths, but the low carriage, wide stance, body shape, black tuft in front and large face all resemble that family as far as I can tell, so this is my best guess. Thanks again for your submission and have a great fall!
