I have finished reading "The Early Asimov" Book 1-3 in Japanese. The stories here was written from 1939 to 1948. Last story is " Mother Earth", which looks like prototype or model of " The Caves of the Steel" in 1954. I have read Asimov a lot in these 5 months. So I will take some rest for a while, start to study English again and read books about the United States, etc.
PS: Yesterday I had a dinner with my friend at a bar in Shinbashi, Tokyo. This is my favorite place to have a drink. Very small (counter only, full if 7-8 customers) and cozy bar where I can enjoy good beer, Japanese sake and Japanese shochu. Tomorrow I will attend the golf tournament which is arranged and organized by the owner of this bar.
