Domo-Kun is one of my favorite characters. I was gifted a little stuffed Frankenstein Domo by my great-grandma on Christmas one year, and I fell in love with him. The next year Domo would have a massive collaboration with Target for Halloween, in which many stores would be completely overhauled to be decorated for the collaboration. This just furthered my love for the character, although I really had no idea who the character really was. After doing some research on my Nintendo DSi, I learned that Domo was a mascot for NHK, a Japanese broadcasting corporation. I discovered a website called DomoNation which was an official Domo fan website that hosted Domo-themed games, merchandise, and news, and allowed users to upload their own Domo images. Some users took photos of them with their Domo merchandise, some uploaded photoshopped images of Domo, and some uploaded some really offensive images that somehow stayed at the top of the site for multiple months with no moderation. Others uploaded images like this though, of a kid with a mascot costume of Domo-Kun and his roommate Mr. Usaji.
The reason the image is so small is that while a lot of the website was archived on the Wayback Machine, not every individual webpage was archived, and a lot of the webpages that were archived were unfortunately archived without the images or media that once existed on the page. Despite this, the main web pages that are archived do still have images, although many are smaller thumbnail photos. I haven't done
too much digging, but for now many of the original high-quality images from the site are lost media.
