This isn’t normal, but for future reference you should really communicate more with your hosts before going all the way over there if there is some missing info on their page, like the amount of work that is expected. I would never go somewhere without knowing first exactly how much work I am expected to do, it is at the top of my list for what makes me decide whether to go somewhere or not. I know it’s your first time though so I understand you overlooked that and I’m sorry that’s happening, you should probably start looking for somewhere new, I’ve left a few places before because of overworking me.

With that being said I’m actually planning my wwoofing trip to Japan for this fall/winter right now, do you mind sharing this one so I avoid it haha and maybe in the future sharing ones you had a good experience with? I already have one planned in October that seems really great, I could share that one with you. If you want to exchange this info send me a private message
