I am ENL
@Truthseeker I'm sorry, my «Red» comment was a typo. I'm resistance and I corrected it in my next comment
This tesseration passcode was gosashikofun, but the gosashikofun “五社神古墳” that exists in Japan is also called Jingukogoryo “神功皇后陵”, and the portal name is Jingukogoryo.
Truthseekers told us Here is the clue to this Tessera's location. Find the name of the portal to retrieve this Tessera.
The question Isn't it a mistake in the question that the passcode is not the name of the portal?
As @10969 says, I think so.
I can't translate from 神功皇后陵 to Gosashikohun even using Google Translate.
You wrote, "Find the name of the portal to retrieve this Tessera."
If so, I think the answer should be the Romanized version of the Japanese reading, or the correct English translation.
I don't think that this point should affect the results, but I hope that it will be helpful when the Japanese portal becomes the answer in the future.
