A titanosauriform dinosaur: Fukuititan nipponensis gen. et sp. nov. is erected based on the incomplete skeleton. It is characterized by elongated asymmetric tooth crown with a weak or absent labial groove and without lingual concavity; stalk‐like epipophysis of cervical vertebra; the transverse width of the proximal end of the humerus approximately 32% of the humerus length; metacarpal longer, approximately 48% of the radius and the distal end of the ischia slightly expanded. It represents the first relatively complete titanosauriform skeleton found from Japan. The discovery of Fukuititan indicates that the diversity and geographical distribution of Titanosauriformes are much higher than the previous thought.
