After the middle of the nineteenth centurythe native mathematics
of Japanyielded to a strong influx of Western mathematics. The
movement in Japanbecame a part of the great international advance.
In 1911there was started the Tôhoku Mathematical Journal, under
the editorship of T. Hayashi. It is devoted to advanced mathematics,
contains articles in many of our leading modern languages and is quite
international in character. ¹

Looking back we see that Japanproduced some able mathemati-
cians, but on account of her isolation, geographically and socially,
her scientific output did not affect or contribute to the progress of
mathematics in the West. The Babylonians, Hindus, Arabs, and to
some extent even the Chinese through their influence on the Hindus,
contributed to the onward march of mathematics in the West. But
the Japanese stand out in complete isolation.
