As 710 can be pronounced as 'nanto,' meaning both 'how' and 'Nanto' in Japanese, there are some puns to describe the year of the transfer of the capital, such as 'how beautiful Heijo-kyo is,' 'how big Heijo-kyo is,' 'how nice Heijo-kyo is' and 'how lovely Heijo-kyo is.'
遷都の年号の語呂合わせは「710（南都）きれいな平城京」、もしくは「710（南都）大きな平城京」、「710（南都）素敵な平城京」、「710（南都）美しい平城京」など。
