ビンタン島
Batam is a roughly oval island with many bays, islets, and peninsulas, located west of Bintan Island, south of Singapore, north of Rempang and Galang, and east of Bulan Island. The Riau Strait separates Batam and Bintan. Batam Municipality covers 3,990 km², of which 1,040 km² is land, a figure which includes some land reclamation. However, "Barelang Island" (not actually one but three, see above) covers roughly 715 km² of that 1,040 km², and Batam island itself covers only about 410 km² out of the total. The bulk of the municipal population resides on Batam island.
