Questions & Answers about kono toukyuu wa ii.

What does この mean here, and why is it used before 投球?

この means this, but it must be followed by a noun.

So:

• この投球 = this pitch / this throw
• この cannot stand by itself
• if you want to say this by itself, you would use これ

Compare:

• この投球はいい。 = This pitch is good.
• これはいい。 = This is good.

A very common beginner mistake is trying to use この alone. In Japanese, この / その / あの must directly modify a noun.

What does 投球 mean exactly?

投球 literally refers to a thrown ball, a pitch, or pitching, especially in a baseball context.

Depending on context, it can mean:

• a single pitch
• the act/style of pitching
• a thrown ball in sports discussion

So この投球はいい。 most naturally sounds like something said while evaluating a baseball pitch or a pitcher’s throw.

For everyday throwing in a non-sports context, Japanese might use other words depending on the situation. 投球 sounds fairly sports-related.
