With the support of the Saudi Arabian government, the headquarters was relocated in 1407H which corresponds to 1987G to the former building of the Saudi Embassy in the strategic Minato-Azabu district. This move contributed to its stability.

Rebuilding period (1996-1999):
The Custodian of the Holy Mosques, Allah safeguards him, decided to build a new headquarters for the Institute.
