#21 (September 1973), pg. 2, The BGA Greet Mr. Takagawa
The Japan Air Lines sponsored and staged a most entertaining and educational Go session. This was held at the Hanover Grand Hotel Banqueting Rooms, Hanover Street, London, on Wednesday, August 1st.
Place of honour was given to the greatest of all modern Go players, Mr. Takagawa. Mr. Takagawa gave comments on a game between his fellow countryman, Mr. Nakaoka, a 7th Dan Professional, and the British Champion, John Diamond. (…)
There were approximately 100 people in attendance, representing 10 of the major Go Clubs in this country, and a couple of overseas visitors from Amsterdam.
Note that he is always referred to as Mr. Takagawa, never merely Takagawa. This was the style of the time.
