Poetry Kanto journal's origins can be traced back to the founding of the Kanto Poetry Center in 1968 by Professor Emeritus William I. Elliott, when he proposed a four-fold center to be housed at Kanto Gakuin University—the first of its kind and scope in Japan, to include a library of contemporary poetry, a poetry journal, regular poetry readings in the university, and an annual poetry conference. The Center, modeled after American counterparts, was originally directed by Kanto Gakuin's Prof. Naoyuki Yagyū and his colleagues, Kazuo Kawamura and William I. Elliott, and has over the years sought, in Elliott's words, "to promote the
2011 Tōhoku earthquake and tsunami and south. From the averaged coupling coefficient of 0.5–0.8 in the source area and the seismic moment, it was estimated that the slip deficit of this earthquake was accumulated over a period of 260–880 years, which is consistent with the recurrence interval of such great earthquakes estimated from the tsunami deposit data. The seismic moment of this earthquake accounts for about 93% of the estimated cumulative moment from 1926 to March 2011. Hence, earthquakes with magnitudes about 7 since 1926 in this area only had released part of the accumulated energy. In the area near the trench, the coupling coefficient
