Assuming you are referring to the Haniwa HCTR01, I note that the Haniwa phono stage that is recommended for use with it has an input impedance of only 4 ohms (!), undoubtedly as a consequence of the ultra-low resistance and ultra-low inductance of that cartridge. And it is indicated that tracking force can be significantly reduced when that loading is applied. So load resistors having values in that vicinity should presumably be among those you try.
As Ralph of Atma-Sphere has explained in various threads here, and as alluded to above by Artemus_5, the design of the specific phono stage that is being used, and how gracefully it is able to handle RF frequencies, is usually the major determinant of what loading value is optimal for an LOMC. But I suspect that the uniquely low values of inductance and resistance of this cartridge, together with the mechanical aspects of its design, are likely to result in it being an exception to that general rule.
Good luck. Regards,
