* No word needed: Often, the equivalent of "the" is simply omitted in Japanese. The context makes it clear what is being referred to.
* This/That/These/Those: Words like これ (kore - this), それ (sore - that), あれ (are - that over there), これら (korera - these), それら (sorera - those), あれら (arera - those over there) can function similarly to "the" when referring to something already established.
* Specific articles/nouns: Sometimes, the specific noun itself, combined with context, makes the "the" unnecessary.
* Possessive particles: Particles like の (no) can be used to show possession, which can sometimes act like "the" in phrases like "the president's house" (大統領の家 - daitōryō no ie).
Therefore, there's no single answer. You need to provide a sentence using "the" to get a proper translation.
