Amanresorts International Pte. is known for providing luxury accommodation far from the madding crowd, but its latest retreat overlooks Tokyo's financial district.

After accumulating 27 properties from French Polynesia to the Himalayas, Singapore-based Amanresorts will open its first urban hotel atop a tower block in the capital on Monday.

The move, which comes amid a spat between the resort operator's co-owners, Omar Amanat and Vladislav Doronin, is part of a plan to more than double its roster of hotels and boost occupancy rates as companies including luxury giant LVMH Moet Hennessy Louis Vuitton SA expand into hospitality.
