How to say "One" in Japanese

Both words can translate to "one", but which should you choose?

Japanese Option A

一因

いちいん (ichiin)
N2 / CEFR Syllabus
VS
Japanese Option B

逐次

ちくじ (chikuji)
N2 / CEFR Syllabus

Nuance Contrast & Translation Difference

When translating "one" into Japanese, you must choose carefully between 一因 and 逐次. In Japanese, 一因 (いちいん (ichiin)) is typically associated with "one cause; a contributing factor" (Syllabus Level: N2) and represents Used to indicate one of several causes or factors contributing to a situation, often a negative one.. On the other hand, 逐次 (ちくじ (chikuji)) maps to "one by one, successively, in order, sequentially" (Syllabus Level: N2) and represents Used to describe actions or events that happen in sequence, one after another, often in a formal or administrative context.. A literal translation of "one" can often sound unnatural to native Japanese speakers if mixed up!
