This page says No. 210 and No. 429 are "hymns with original Japanese words."
210. "Kiyoki tokoro o tsukureyo to" -- "Build a Holy Place for Me" (CROSBY) 492. "Kami no megumi wa ito takashi" -- "Like Mount Hermon's Lofty Peak"(CROSBY)
What do these English words mean? Titles of the original tunes? First lines? Google search has returned this page. Megumi Hara's book on hymns (Sanbika, 1980) doesn't say anything about these hymns. Incidentally, No. 210 is adopted by Sin-Seika (Kyobunkan, 2001, no. 498), successor to Seika (Nihon Fukuin Renmei, 1986). No Crosby hymns are contained in the new Sanbika 21 (1997).
