We propose to obtain NIFS K-band spectra of 7 massive young stellar objects candidates with clear evidences of accretion process. They were selected from a sample of 70 MYSOS candidates, which is part of our Galactic survey for high mass stars in formation. IFU observations combined to PCA tomography can improve the instrumental spatial resolution and resolve the inner part of the accreting disks associated to our targets. This result will also be used to derive the dynamical mass of the central star and its disk.
