"Kami membeli peralatan ini dari Jepang."

Translation: We bought this equipment from Japan.

[NudibranchsRcool]

"We buy this equipment from Japan." = not accepted. Reported.
There is no indication of past so not sure why "buy" couldn't be accepted.

[donny309620]

No indication of tense, so yes "buy" should be accepted

English translation not good. You buy something 'in' a country. I know membeli means buy but do they mean the equipment was 'brought' from japan?

[Chiliem]

Had the exact same thought. Although what could be meant is 'We buy/bought this 'equipment from japan' - as in 'made in japan'. Although in that case I would literally mention the made in Japan. Else I'd go for We buy/bought this equipment in Japan.
