Nikkei - Japan another lost decade?

Is Japan headed for another lost decade. The failure to go above the multiple highs of wave B, raises the possibility that what Japan just finished is wave X of an ongoing Grand supercycle bear market. Wave Y down would unfold over another decade taking it back to 5000. The X wave would be an expanded flat from 2003-2015 and explains the wave formations for this period quite well. Time wise of Y=W it would end by 2024.
