The date and location is uncertain. The Davis Septet toured Japan from January 22-February 8. This music circulates as from Kokura, February 3; but the itinerary has Davis at City Hall in Kokura on January 30 and at the Sunpu Hall in Shizuoka City on February 3:

January 22 (Wed): Tokyo Koseinenkinkaikan Hall (7:00 pm)
January 23 (Thu): Tokyo Koseinenkinkaikan Hall (7:00 pm)
January 24 (Fri): Nagoya Shiminkaikan (Nagoya civic auditorium) (6:30 pm)
January 25 (sat): Kyoto Kaikan Hall (No. 1) (6:30 pm)
January 27 (Mon): Sapporo Koseinenkinkaikan Hall (6:30 pm)
January 30 (Thu): Kokura Shiminkaikan (City Hall) (6:30 pm)
February 1 (Sat): Osaka Festival Hall (two concerts, 4:00 pm and 7:00 pm)
February 2 (Sun): Osaka Festival Hall (2:00 pm)
February 3 (Mon): Shizuoka City Sunpukaikan (6:30 pm)
February 4 (Tue): Miyagi Kenminkaikan (6:30 pm)
February 7 (Fri): Tokyo Koseinenkinkaikan Hall
February 8 (Sat): Tokyo Koseinenkinkaikan Hall (two concerts, 2:00 pm and 7:00 pm)

An erroneous date is easier to account for than a mistaken venue, so I'm guessing this is really from January 30.

Several of the concerts were recorded and broadcast on Japanese radio. Thanks to Eric Jooris for providing me with a copy of the concert program, and to Tom Yamaguchi for translating the schedule for me.
