Morse noticed the mound as he rode the train from [[Yokohama]] to [[Shinbashi]] in June 1877, and returned to the site shortly afterwards to excavate it. Pottery shards, stone tools, human and other bones, and shells found in the mound revealed much about prehistoric Japan. Morse's findings, published in [[1879]], were among the first modern scholarly work on prehistoric Japan to be published in either English or Japanese. | Morse noticed the mound as he rode the train from [[Yokohama]] to [[Shinbashi]] in June 1877, and returned to the site shortly afterwards to excavate it.
