The spelling of /t/ is <t> and we also see a silent letter combination <tw> in two. The /j/ sound is <y> or <ew> in ewe and occurs in the letter name U. All the pairs but one show the sounds contrasting initially in the word. I discarded reluctantly the pair Toto/yoyo. The two common pronunciations of your make pairs with tore and tour.
The contrast is between a voiceless plosive and a voiced semivowel, fairly close together in the mouth. It is not a problem for learners.
Interesting pairs include:
sorter sawyer toga yoga
