A day tirp to Tokyo

I took a day trip to Yokohama and Tokyo yesterday with a Cambodian.At first, I visited Yokohama to collect material for my study at afternoon.After that, I moved to Tokyo. I met a Korean and 3 Cambodian that live in Tokyo, and we ate dinner. Mr.Kim, Lim(a travel agency and the Cambodian Embassy in Japan?), ニェット(a planning office for construction)、ソーワン(he studied at TUT before.) They are good and I could enjoy talking while drinking beer. hahaha. And then, we returned to Toyohashi by a midnight bus at this morning.I felt it's a long day.
