I visited the National Museum of Korea last time and was able to see Buddhas.
This is the Vairocana.
Vairocana (also Vairochana or Mahāvairocana, Sanskrit: वैरोचन) is a celestial buddha who is often interpreted, in texts like the Flower Garland Sutra, as the Dharma Body of the historical Buddha (Siddhartha Gautama).
In Chinese, Korean, and Japanese Buddhism, Vairocana is also seen as the embodiment of the Buddhist concept of Emptiness. In the conception of the Five Wisdom Buddhas of Mahayana and Vajrayana Buddhism, Vairocana is at the centre and is considered a Primordial Buddha.
