Subaru Telescope bụ telivishọn Ritchey-Chretien na-egosipụta. Enwere ike itinye ngwá ọrụ [2] Cassegrain focus n'okpuru enyo isi; na nke ọ bụla n'ime ebe abụọ Nasmith focus n'ime ogige dị n'akụkụ ugwu telivishọn, nke a pụrụ iji enyo nke atọ duzie ìhè; ma ọ bụ na isi ihe n'ọnọdụ enyo nke abụọ, ndokwa a na-adịghị ahụkebe na nnukwu telivishons, iji nye ohere dị ukwuu maka nyocha dị omimi.

N'afọ 1984, Mahadum Tokyo guzobere otu ọrụ injinia iji mepụta ma mụọ echiche telivishọn 7.5-meter (300 in). N'afọ 1985, kọmitii na-ahụ maka mbara igwe nke kansụl sayensị nke Japan nyere ihe kachasị mkpa maka mmepe nke "Japan National Large Telescope" (JNLT), na 1986, Mahadum Tokyo bịanyere aka na nkwekọrịta na Mahadum Hawaii iji wuo telivishọn na Hawaii. 'afọ 1988, e guzobere National Astronomical Observatory nke Japan site na nhazi nke Tokyo Astronomical observatory nke Mahadum ahụ, iji lekọta JNLT na nnukwu ọrụ ndị ọzọ nke mba.

Iwu nke telivishọn Subaru malitere n'ọnwa Eprel afọ 1991, ma ka e mesịrị n'afọ ahụ, asọmpi ọha na eze nyere telivishons aha ya, "Subaru Telescope". [3] wuchara ya n'afọ 1998, e wepụtakwara foto sayensị mbụ na Jenụwarị 1999. [4] Septemba 1999, Princess Sayako nke Japan raara onyokomita ahụ nye.
