Since spectroscopic observations require a large telescope and a spectrograph of
adequate resolution, Yerkes Observatory made a strong impression on Ichinohe, not
only for its instrumentation, but also in its free conception for observational projects.
Ichinohe thus became convinced that the future of astronomy in Japan should follow
the American style in instrumentation as well as in its operations.
Ichinohe was a talented writer. Before setting off for the Uunited States, he wrote
a book and produced a translation. Both were published during his stay in America.
The first one was Koto Tenmon Gaku (高等天文学, Advanced Astronomy), a
mathematical treatise on spherical astronomy and the structure of the Solar System.
The second one was Seishin Tenmon Gaku – Uchu Kenkyu (星辰天文学•宇宙研究,
The Stars: A Study of the Universe), which is a Japanese translation of Simon
