The letter was found in the Russell Archives before they came to McMaster by the editors of Dear BR and reproduced there in facsimile on p. 36 of the first British edition (p. xxxvi of the first American) and on the rear of the U.S. dustjacket. The letter cannot be found in RA and is assumed not to have arrived.

The writers are all professors at Hosei University, Tokyo. They are impressed by BR's decision to go to prison rather than abandon plans to protest nuclear weapons.

For the reply, see document .051290, record 77843. Not indicated on the reproductions is the notation in the upper-left corner, "Ans / copy attached". This can be seen on the photocopy of the letter in the black bound printer's copy of Dear BR (document RA2 210.147507).
