poem monument of yosano hirosh, hakodate

I passed by the poem monument of Yosano Hirosh and I recorded the English text next to the monument. Here's what it said:

In 1956 the 13th anniversary of Okada Kenzo's death was held. Okada Kenzo is known as the founder of Hakodate Municipal Library and he served as its first curator.

On this occasion, Toshorikai, an association of book-lovers was organized and was named after Okada's pen name. In 1957 this association erected a monument in honor of Okada Kenzo on which has been inscribed the poems composed by Yosano Hiroshi (a famous Japanese poet known by his pen name Yosano Tekkan) and Yosano Akiko who had come to Hakodate in 1931, with the support of the Bonimoriya company.

Okada Kenzo has been described in the poem of Yosano Akiko as Okada Sensei (great teacher). And in the poem by Yosano Hiroshi, Okada Kenzo's best friend, Miyazaki Ikuu, appears.
