In 2004, one of our members visited Yahiko Jinja in Niigata, Japan. There was a sword museum next to the shrine which housed two of Japan's biggest swords.
There is however some conflicting information that needs to be cleared up:
These two links show an odachi called the Norimitsu Odachi, that's very similar in appearance to the Masayoshi Odachi. According to the links, the Norimitsu odachi, also claiming to be the longest sword in Japan, is displayed at the Kibitsu shrine in Okayama-ken.
Shida Odachi, 2.204m long blade, nakago 1.018m.
