We report a faint non-axisymmetric structure in NGC\,1087 through the use ofJWST Near Infrared Camera { (NIRCam)}, with an associated kinematic counterpartobserved as an oval distortion in the stellar velocity map, \ha~andCO~$J=2\rightarrow1$ velocity fields. This structure is not evident in the MUSEoptical continuum images but only revealed in the near-IR with the F200W andF300M band filters at $2\mu$m and $3\mu$m respectively. Due to its elongation,this structure resembles a stellar bar although with remarkable differenceswith respect to conventional stellar bars. Most of the near-IR emission isconcentrated within $6\arcsec~\sim500$~pc with a maximum extension up to1.2~kpc. The spatial extension of the large-scale non-circular motions iscoincident with the bar, which undoubtedly confirms the presence of anon-axisymmetric perturbation in the potential of NGC\,1087. The ovaldistortion is enhanced in CO due to its dynamically cold nature rather than in\ha. We found that the kinematics in all phases including stellar, ionized andmolecular, can be described simultaneously by a model containing a bisymmetricperturbation; however, we find that an inflow model of gas along the bar majoraxis is also likely. Furthermore the molecular mass inflow rate associated canexplain the observed star formation rate in the bar.  This reinforces the idea that bars are mechanisms for transporting gas andtriggering star formation. This work contributes to our understanding ofnon-axisymmetry in galaxies using the most sophisticated data so far.
