You're absolutely right -- though, while Mandarin’s SVO structure does align with English in basic sentences, what’s interesting is how flexible word order and grammar in general can become in practice, thanks to its reliance on context and particles rather than rigid syntax. For example:

Mandarin often moves the object to the front for emphasis, creating an OSV or SOV structure (e.g., 寿司你吃, "Sushi, you eat" or 你寿司吃了吗 "You sushi eaten?"). This isn’t true SOV grammar but highlights how meaning shifts through word order in ways English can’t replicate without rephrasing.

The nuance in Mandarin often comes from particles that take on very different meanings depending on how they are used (e.g. 了, 的) and contextual cues rather than conjugation. For instance, 吃 "eat" becomes past tense with 了 (吃了), future with 会 (会吃), or continuous with 在 (在吃)—no verb changes needed. But if you say 要吃了, it actually means future tense of "will eat soon"!

Meanwhile, Japanese relies heavily on verb conjugations (食べる→食べた) and postpositional particles (は, を) to mark grammatical roles, in a way making its structure more rigid and easier to interpret. Personally I found Tae Kim's interpretation of "Japanese isn't SOV, it's actually V!" to be useful.

Both languages share subject-drop tendencies (like omitting "I" or "you" when contextually clear), and compound-word formation in both languages from the use of Chinese characters (kanji) adds another layer of contextual interpretation.
