Among the oiran, the tayu was considered the highest rank of courtesan and were considered suitable for the shogun. Only the wealthiest and highest ranking could hope to patronise them. To entertain their clients, similar to a geisha, the oiran practiced the arts of dance, music, poetry and calligraphy and an educated wit was considered essential to sophisticated conversation. The rise of the geisha ended the era of the oiran. Geisha practiced the common entertainments enjoyed by the people of that time, and were much more accessible to the casual visitor. Their popularity grew rapidly and eclipsed that of the oiran. Oiran Dochu is a kimono procession common at certain festivals that celebrate old Japan and Edo.
