Not just an urban myth: You CAN rent pets and boyfriends at Odaiba
A short lull in the rainy season showers and a case of early morning insomnia gave me a chance to pop across the Sumida River on the new Harumi Doori bridge to Odaiba - as far as the Evergreen container docks at the far end past the Maritime Museum. By chance I drove past the ground level of the Venus Fort shopping mall and was happy to confirm that, yes, indeed they do offer rental puppies with all kinds of goodies, including frequent-buddy miles and cake for both pet and person after the walk. Check it out if you haven't yet had a chance.
