Building a temple of this scale was expensive. Takauji and Retired Emperor Kōgon donated estates to support the construction, but it still was not enough. So Takauji's brother Tadayoshi consulted Musō and came up with a bold plan: reopen trade with Yuan China, which had been cut off since the Mongol invasions, and use the profits to fund the building work. That is the origin of the Tenryū-ji ship, a trading vessel named after the temple. It is a wonderful reminder that a Zen temple, a place we now associate with stillness, was once tied to overseas commerce and politics. The temple's standing grew quickly. In 1346, Musō chose 10 spots in and around the grounds as places of special beauty, known as the Ten Views of Tenryū-ji, and wrote poems for them. They include the Sōgen Pond, the Togetsu Bridge, and the Ryūmon Pavilion. Then in 1386, under Ashikaga Yoshimitsu, the Five Mountains of Kyoto and of Kamakura were formally reorganized, and Tenryū Temple was placed first among the Kyoto Five.
