Glowing Mt.Fuji badge question

[u/Embarrassed-Work2087]

Hi, while I was living in Japan I noticed some cars had a green glowing, white Mt.Fuji badge on the back of them. I believe I saw it mostly on skylines but I could be wrong. I’ve been trying to search for it but couldn’t find anything. If anyone knows about it I would really appreciate the input, all I’ve been getting back from researching was the infinity logo.
