Are you looking for an enka style or a national style?
Go and listen to Ji Shen’s poem, in the style of a famous clan, recommending the poems of the gods and transcending love.
Moto Chitose’s songs are more similar to enka, such as the 语り久ぐこと in "blood+".
The Shini Akenoha Yuki is also good
Moriyama Naotaro and Natsuki Nozomi are also very interesting
