I lived in Tohoku, Japan for five years. Traditional guidebooks have almost no English language information on Tohoku, so I hope Wikivoyage can fill the gap. If there is any information you'd like on an area I've lived or frequented, please ask. I'd love to add more information wherever it's desired.
