Rolland,
Yes, unfortunately page 18 which would be the Air-Sea Rescue chart designating lifeguard stations along the bombers route is missing.
This was a two night incendiary strike on the Tokyo urban area. Here is a link to the Tactical Mission Report for Mission No. 181 flown the night before 23/24 May 1945. This report
does include the lifeguard chart

It is unknown to me how much assignments might have changed for the lifeguard station locations but it is suspected that they would have been very similar.
