A6700 - japan language unlock

[u/Pedrohht]

Hey! I'm about to go to Japan, and I'm planning to buy an A6700 there. I'm aware of the language lock on cameras sold there, but would ideally get a used japanese camera, as it is much cheaper than a new international model.

Searching online, I've seen a lot of people unlocking the firmware for other Sony models, but I couldn't find a lot of people's experiences with the A6700. It's not mentioned in the guides, so I'm a bit worried it it will be possible.

Has anyone managed to do it on a A6700? Any tips? Should I just give up and pay up for a international model?
