Questions & Answers about kaisaisuru ka douka wa, tenki to kaijou no nittei de kimarimasu.

What does 〜かどうか mean here, and how is it different from just 〜か?

• 〜かどうか means “whether or not.” It attaches to the plain (dictionary) form: 開催するかどうか = “whether or not (we) hold it.”
• 〜か alone can mean “whether,” but for yes/no situations, Japanese usually prefers 〜かどうか. Using just 〜か often sounds incomplete unless:
  • you list both alternatives: 行くか行かないか (“whether to go or not”)
  • or the structure clearly licenses bare か (less common).
• Safe rule: for a yes/no “whether,” use 〜かどうか.

Why is there a は after 〜かどうか? Could I use が instead?

• は marks the whole clause 開催するかどうか as the topic: “As for whether it will be held…”
• が is also possible: 開催するかどうかが、天気と会場の日程で決まります。 Here, the clause is the grammatical subject. Nuance:
  • は: sets up a topic (background/contrast), very natural in expository statements.
  • が: marks it as the subject and can feel a bit more “new information” or focused.
• Both are correct; は is common for this kind of “As for whether X…” statement.

Why is it 開催する (plain) inside 〜かどうか and not 開催します?

• Inside embedded questions (and most subordinate clauses), Japanese uses the plain form. Politeness appears at the sentence end: …決まります.
• So you get 開催するかどうかは…決まります, not 開催しますかどうかは… (incorrect).

Would 開催されるかどうか be better than 開催するかどうか?
