How do you say "I think so too" in Japanese?

Quick use

Use わたしもそうおもいます (watashi mo sou omoimasu) when someone gives an opinion and you want to say you think the same thing.

Chunk or pattern

• This is a fixed agreement phrase.
• Learn the whole line first.
• It is useful when はい alone feels too short.

Core words

• わたし: I.
• そうおもいます: I think so.

Helper words and endings

• も: also / too.

Practical note

This agrees with an opinion or impression. For a simple factual yes/no question, plain はい may be more natural.
