We have detected the second flux rise since 2023-2024 in the 6.668 GHz Class II methanol maser toward G11.497-1.485 (IRAS 18134-1942) (RA, DEC) = (18h16m22.13s, -19d41'27.100") using Hitachi 32-m radio telescope operated by Ibaraki University. The flux density before MJD = 61115 (16/Mar./2026) for the velocity components of VLSR = 16.8 km/s is ~20 Jy. The flux density increased to ~150 Jy at MJD = 61156 (26/Apr./2026).
