After the Great Fire of Tenmei, the roji at Omotesenke changed completely. Fushin'an was separated from Zangetsutei and moved to the east. The roji which had previously faced from south to north now faced from west to east. The roji was positioned south of Zangetsutei so that it was possible to enter the Zangetsutei from the roji. A new seven mat practice room (shichijo) and Sodo (Founder's Hall) were built by Sottakusai. Finally in the time of Kyukosai a separate Sodo was built facing west to the south of the Zangetsutei tea garden.

So there was a complex arrangement of roji at Omotesenke, with the outer roji on the west side, the roji in front of the Zangetusutei, Fushin'an's inner roji on the east side and the roji in front of the Sodo. In Meiji 39 (1906) Omotesenke was destroyed by fire except for the Rikyudo (Founder's Hall), but it was restored almost unchanged and this is what survives today.

Fushin'an, which was rebuilt in Taisho 2 (1913), is said to have remained almost the same inside and outside since the time of Koshin. It is the tea room which symbolizes Omotesenke and stands in that part of the roji which is furthest from the entrance, facing south.
