  Provided are an ink composition having a fastness at a high level and having an excellent grey balance in a range from a high-concentration region to a low-concentration region, an ink for inkjet recording using the ink composition, and an inkjet recording method using the ink for inkjet recording using the ink for inkjet recording. An ink composition containing at least two kinds of water-soluble long-wavelength dyes whose absorption spectrum in an aqueous solvent has a maximum wavelength of 550 nm to 700 nm, in which at least one kind of the water-soluble long-wavelength dyes is a first water-soluble long-wavelength dye of an azo compound represented by the following Formula (1), at least one kind of the water-soluble long-wavelength dyes is a second water-soluble long-wavelength dye that is different from the first water-soluble long-wavelength dye, and the second water-soluble long-wavelength dye is a compound having two to four azo groups conjugated with each other per molecule, an ink for inkjet recording using the ink composition, and an inkjet recording method using the ink for inkjet recording using the ink for inkjet recording. Formula (1): (In Formula (1), A represents a substituted or unsubstituted aryl group or a substituted or unsubstituted nitrogen-containing 5-membered heterocyclic group. G represents a nitrogen atom or -C(R2)=. R2 represents a hydrogen atom, a sulfo group, a carboxyl group, a substituted or unsubstituted carbamoyl group or a cyano group. Y2, Y3 and Y4 each independently represent a hydrogen atom or a monovalent substituent. Y2, Y3 and Y4 may be bound with each other to form a ring. All of Y2, Y3 and Y4 do not represent a hydrogen atom at the same time. M's each independently represent a hydrogen atom or a monovalent countercation.)
