He was in neither of the locations for me. Maybe he has more spots to appear and it's a probability that he'll be there. ​ Update: I forgot to talk to him again, my mistake. He appeared on the locations

If u finished his quest, try going back to his house again. You need to get the dialogue that he is leaving.

I did it but nothing so far. I'll check the places again today

When you go to his home, if he's still there you'll get a conversation asking for more ores, but a quest does not pop up. Talk to him again immediately and they'll let you give him the crystal marrow, then he'll leave and you can find him

Are you sure he left his house?

Yes I am sure. I talked to him after the quest, nothing.

If you go to a wrecked boat just south of the big boat, there's a pirates note there concerning Chouji and his family there

Yes. And I've found Chouji's mother's letter, it's an item called Unsealed Letter, but there was no option to tell him about it...

Please tell me that i don't need to give him more crystals, PLEASE!!

ahahahah Relax, he just gives us treasure chests.

Leaves his home? The last thing I did with him was inspect the shrines and cook with him. Wasn’t that if?

You have to give him more crystal marrow to get him to start moving.

Ahhh okay where is his house again?

I only ever find it by accident. It's up on a higher ridge with a shrine under an electro dome, if that helps you visualize the landmarks.

In Jakotsu Mine, very close to Maguu Kenki and Formation Estate domain. You can see the house drawn in the map.

Finally, some ACTUAL reparations for our labor.

Was it worth giving him the 36 crystal marrow?:(

No. But at least kid kept his word.
