Okuyo Maru standard speed was 11,5 knots. As far as I know her maximum speed was 14 knots.
450km is 242,98 nautical miles.
242,98/14 = 17.36 hours
242,98/ 11.5 = 21.13 hours
If she takes a route closer to the New Guinea coast her standard speed is likely not fast enough to arrive within 24 hours at Kayumerah.

Thanks for the comment. "Okuyo Maru standard speed was 11,5 knots." is good information. But I don't think "24 hours" is necessarily an absolute requirement. More important thing is "Departed on the 8th and Arrived on the 9th". When she departs early on the 8th and arrives late on the 9th, her voyage time can exceed 24 hours.

A 1941 Japanese map matches the location given by Akira Takizawa above.

The question I have is WHY? no obvious facilities on the island or nearby. just a good anchorage, hiding from allied aircraft, scouting for airbase sites?
Possibly カユメラ was a waypoint for reinforcements and supplies to the Mimika defense force.

Hakko Maru (1,132 tons) also made a trip to Kayumera and then went on to ケクフ. So here we go again - where is ケクフ
When? Cam you show the Kanji for Hakko Maru?

Fontessa. Hakko Maru arrived at Kayumera on Feb 15th 1943 and departed on Feb 16th for that unknown Kekufu...

her kanji was 八 紘 丸

I have 5 Hakko Maru's in my database with the same kanji. this one was the ex- Randi

18.01.25: dep Ambon - 02.15 arr Kayumera dep 02.16 - 02.20 arr Kekhu dep 02.23 - 02.28 arr Ambon
did not enter departing Ambon on 1/25 because the time span is too large. It couldn't have taken 21 days to go from Ambon to Kayumera so we are missing a gap here re her travels
But it does seem that the mystery Kekhu was about 4 - 5 days sail away from Ambon.

Around this time, the IJA was strengthening the Mimika defense system. As mentioned earlier, カユメラ was a waypoint, and ケクフ was also the same. So the final destination was Mimika.

I will upload the details later.

Fontessa,

Thank you for the research you did and for posting such detailed information on these movements!
It is way too late for me to even try to learn Japanese - I especially cannot read handwritten characters so I am always grateful for your contributions.

Following up I was just looking at Google maps at Mimika (Mimako) and see that there is a town just south of Mimika with a much better landing site -
Keakwa - this must obvioulsy be Ke Ku Wa

See the below Military Map. Uta is the reference point with Google Maps.
