The former Rafu Daiichi Gakuen was destroyed in a fire. This pictures shows the second location of the Rafu Daiichi Gakuen.

The poem below describes the event:
The Gakuen That Became The Parent Potato

Fastening her expectations upon
The success of her child,
The Parent Potato withers away.
Thus,it is written-by the hand of Destiny
Rafu Daiichi gakuen too;
Forfeiting lands and monies for seven long years,
Unflinching, unfailing,-nourished Eight Branches,
A gift to posterity.
And someday, she too may wither away,
Yet;
This great Contribution,
As the pioneers of old,
Can never be forgotten,
nor shall it be in vain.
