Ten years of Hinode operation have indicated the direction of the new challenges in solar physics. The task of the next solar observation missions is to determine the three-dimensional (3D) structure of magnetic fields that connect the photosphere and the corona by resolving the elementary magnetic structures in the solar atmosphere. SOLAR-C is the long-awaited next-generation international solar physics satellite that will observe the magnetic field of the chromosphere and the plasma dynamics from the photosphere to the corona with much higher spatial and temporal resolutions than Hinode. To this end, the Japanese solar physics community is promoting a sounding rocket experiment, the Chromospheric Lyman-Alpha SpectroPolarimeter, and a balloon experiment, SUNRISE-3, to pave the way for measuring the chromospheric magnetic fields with spectropolarimetry in the ultraviolet and infrared, respectively. Additionally the algorithm for determining the 3D magnetic field from spectropolarimetric data is investigated using a newly developed multi-wavelength spectropolarimeter at the Hida observatory. Solar telescopes with 4 m aperture are expected to begin operating in Hawaii and the Canary islands in the 2020s and introduce a new approach to uncovering fine-scale structures with the highest-ever spatial resolution. The continuous and high-precision observation by SOLAR-C, which has large spatial and temporal coverage, will contribute indispensable information for understanding the fundamental plasma process occurring in the Sun and in the Universe and for establishing the foundation for the next-generation space weather prediction.
