あと means after.
When it follows a verb, the verb usually shows the action that happened first.
So:
The past form 食べた is normal here. In Japanese, verb-past + あと is a common pattern for after doing X.
Compare:
So the tense before あと does not mean the whole sentence is “extra past”; it is just the standard grammar pattern.
Most likely, yes.
Japanese often leaves out subjects when they are understood from context. In this sentence, 祖父は appears in the main clause, so the natural interpretation is that the grandfather is also the person who ate the sashimi and tempura.
So the implied meaning is:
That said, Japanese does sometimes allow this kind of omission even when English would want a clearer subject. Context decides.
は marks the topic of the sentence.
So 祖父は means something like:
The sentence is telling us what happened with respect to the grandfather.
A learner might expect が, but は is very common when introducing what the sentence is about, especially in ordinary narration.
祖父 and おじいさん can both refer to a grandfather, but they are used differently.
In many contexts, when speaking about your own family member to someone else, Japanese prefers the plain family term like 祖父 rather than the more honorific-sounding おじいさん.
Because they are doing different jobs in the sentence.
In Japanese, the main verb usually determines the sentence’s politeness level. Subordinate parts like 〜たあと often stay in plain form even in polite sentences.
So this combination is completely normal:
温かい means warm and is commonly used for things that are warm to the touch or pleasant in temperature, including drinks like tea.
Japanese has both:
So for tea, 温かいお茶 is the natural choice.
Japanese usually follows Subject/Topic – Object – Verb, and time expressions often come before the main clause.
This sentence is structured like:
The verb normally comes at the end of the clause in Japanese. That is one of the biggest differences from English.
They are read:
A common point to notice is that 祖父 is そふ, not そぼ.
Yes. It can be written as 後.
So:
Both are correct. In everyday writing, many learners will see both versions. Using hiragana for あと is very common and often easier to read.
Because 食べたあと already forms a complete time expression: after eating.
It directly connects to the main clause, so you do not need another particle there.
The comma simply helps readability:
Without the comma, the sentence would still be grammatical, but the comma makes the pause clearer.
