RX J1713.7-3946 is a unique core-collapse SNR that emits bright TeVgamma-rays and synchrotron X-rays caused by cosmic rays, in addition tointeractions with interstellar gas clouds. We report here on results of ALMA$^{12}$CO($J$ = 1-0) observations toward the northwestern shell of the SNR. Wenewly found three molecular complexes consisting of dozens of shocked molecularcloudlets and filaments with typical radii of $\sim$0.03-0.05 pc and densitiesof $\sim$$10^4$ cm$^{-3}$. These cloudlets and filaments are located not onlyalong synchrotron X-ray filaments, but also in the vicinity of X-ray hotspotswith month or year-scale time variations. We argue that X-ray hotspots weregenerated by shock-cloudlet interactions through magnetic-field amplificationup to mG. The ISM density contrast of $\sim$$10^5$, coexistence of molecularcloudlets and low-density diffuse medium of $\sim$0.1 cm$^{-3}$, is consistentwith such a magnetic field amplification as well as a wind-bubble scenario. Thesmall-scale cloud structures also affect hadronic gamma-ray spectra consideringthe magnetic field amplification on surface and inside clouds.
