title: Is there a b5paper japanese style in latex?
body: <p>My thesis is written in b5j documentclass style. </p>
  
  <pre><code>\documentclass[b5j,twoside,12pt]{report}
  </code></pre>
  
  <p>I have a paper that is appended at the end. However this is written in b5paper style as an article.</p>
  
  <pre><code>\documentclass[12pt,b5paper,twoside]{article}
  </code></pre>
