The Bay is defined by shoal Umi-no-nakamichi and tombolo Shika-no-shima (Shika Island) to the north, and Genkai-jima (Genkai Island ) to the northwest, and the Itoshima Peninsula to the west. Five wards of Fukuoka city border on the bay, which is sometimes labeled "Fukuoka Bay" on maps. Sometimes, the bay is divided into Hakata, Fukuoka, and Imazu Bays, though for simplicity's sake, the term "Hakata Bay" is commonly used as a catch-all to refer to all three.
The bay is roughly 10 km from north to south, and 20 km from east to west, covering an area of roughly 133 km². The coastline stretches 128 km. The mouth of the bay is only 7.7 km wide, shielding it to a great extent from the waves of the Strait. The bay is only 10 metres deep on average, 23 m at its deepest point, though the tides bring a two-metre change in the water level. Set routes are used, therefore, through the bay, to protect ships' drafts .
Some particular petrified trees in the area are said to have been the masts of ships used in Empress Jingū 's third century invasion of Korea. Veins of mica and pegmatite under the bay, part of a geologic fault , are under governmental protection.
Much of the area is included in the Genkai National Park, and efforts are made to maintain and preserve the natural features and environment both in the bay and on its islands. Though much of the shoreline is natural, some parts, particularly in and around the port itself, are artificial and developed upon; the bay's shoreline was, somewhat crudely, officially designated as natural wilderness and parkland.
A number of small islands are contained either within the bay or around it.

As the closest major bay and port to mainland Asia in Japan, Hakata has played a major role in diplomacy and trade with Korea and China throughout much of history. This also made it, however, a key point of attack for attempts to invade the Japanese islands. In the Toi Invasion of 1019, Jurchens seized several nearby islands, using them as bases from which to raid and attack Hakata.
