How to say "Open" in Japanese

When translating "open" into Japanese, you must choose carefully between 開ける and 打ち解ける. In Japanese, 開ける (あける (akeru)) is typically associated with "to open (something)" (Syllabus Level: N5) and represents Transitive verb. On the other hand, 打ち解ける (うちとける (uchitokeru)) maps to "to open one's heart, to become friendly, to relax" (Syllabus Level: N2) and represents To become less reserved, more relaxed and informal with someone, moving from a formal or tense state to a more comfortable and open one. Often used with the particle 「に」.. A literal translation of "open" can often sound unnatural to native Japanese speakers if mixed up!
