Two Companies

It was very warm yesterday until the evening,
but the wind became cold at night.
In addition the wind became strong last night.

By the way, the day before yesterday,
I visited two companies, and worked there about English.
These two companies are very famous and big,
so everybody definitely knows them.

After I left the first company, I took a picture above.
I worked in a company near the building above.
Could you guess which comapany I went first?

Then I moved to the other company in Akihabara,
and worked there about also English as usual.
