International political scientist Takeshi Wakaizumi, who was involved in secret negotiations with the American side over the reversion of Okinawa and took part in creating a secret agreement regarding the introduction of nuclear weapons, left a will two years before his death expressing his intention to take his own life out of a sense of guilt towards Okinawa. This will is set to be donated to Okinawa Prefecture this year, the 80th year since the end of the war.
