Diary (Island of Japan)

I've come back to Japan.
Today, my friends and I went to the island by motorcycle.
We walked on the beach and went to the museum.
We ate olive Chinese noodles.
My friend ate soy sauce and soft ice cream, too.
It was very fun.

[Good work.  Sounds like a good time.  If you have very recently come back, you could say "I've just come back to Japan".  One question - did you come back FROM Japan or TO Japan.  If you are in Japan now, you came back TO Japan.]
