<h2 id="proposal">Proposal</h2> <p>The plan calls for the building to be made of 90% <a href="/facts/Wood/z13NpHPl">wood</a> with the rest being <a href="/facts/Steel/aN6qWo4H">steel</a>. Steel braces will be used to enhance resistance to <a href="/facts/Wind/Nt0QIu5B">wind</a> and <a href="/facts/Earthquake/NGjIzagw">earthquakes</a>, as the area has high levels of <a href="/facts/Seismic_wave/1JTeLfac">seismic activity</a>. One advantage of wood is that timber-based structures have proven to be very resistant to earthquakes. The project requires 185,000 cubic meters of timber (or 6.5 million cubic feet<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a>), and plans to revitalize forestry and timber demand in Japan.<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a><a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a> The choice of wood, aside from aesthetic and seismic concerns, is part of a larger movement aiming to "change cities into forests".<a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a> Wooden structures are also easier to rebuild or replace than concrete structures if it collapses.<a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a> Two-thirds of Japan is covered by forest, making it the 2nd most tree-covered country of the OECD countries after Finland.
