Natto::MeCab can also iterate through a list of kanji and obtain their most probable readings, using the yomi option for output_format_type and specifying output of the 2 nbest candidate readings:

nm = Natto::MeCab.new('-Oyomi -N2')
=> #<Natto::MeCab:0x288f6d08 
     @tagger=#<FFI::Pointer address=0x28d3ab80>,  
     @libpath="/usr/local/lib/libmecab.so",        
     @options={:output_format_type=>"yomi", :nbest=>2},  
     @dicts=[#<Natto::DictionaryInfo:0x288f6ba0 
              @filepath="/usr/local/lib/mecab/dic/ipadic/sys.dic", 
              charset=utf-8,
              type=0>],  
     @version=0.996>
