The generation of frequency dependent squeezing with ~100 scale filter cavities is a promising technique to obtain a broadband quantum noise mitigation in 2nd generation GW detectors and its implementation is planned in their near-term upgrade. At NAOJ, we are developing a 300 m filter cavity prototype in order to demonstrate squeezing angle rotation below 100 Hz, as required for an optimal noise reduction. The update on the experiment will be presented.
