Skyblazer, do you have a picture of the K-15?
I don't, unfortunately. Even my various Japanese resources do not have it, even in sketch form... :-\

Hi! MXJ1.
Very interesting!! And so there seems to have been a confusion between "7-Shi" and 17-Shi" here.
If Wakakusa was indeed a 7-Shi proposal, then the 17-Shi Nihon Kogata project was something else completely, and not called Wakakusa.
Of course, it could all be a mistake and there never was a 17-Shi Special Trainer Glider. The plot thickens... :-[

Thanks for the picture Skyblaser and clearing the confusion. There is a huge difference between the two gliders.

Actually it's blackkite who posted the picture, but thanks anyway! ;D

I'm beginning to wonder if the mistake did not stem from the Japanese Wikipedia. ???

They list the MXJ1 as 十七試初歩滑空練習機「若草」 . This translates roughly as "17-Shi Wakakusa (Tender Grass) training glider."

Unless there were two different Wakakusa gliders and/or two distinct MXJ1 designations (unlikely) the photo shown by blackkite clearly does NOT show a "17-Shi" (1942) glider, but definitely a "7-Shi" (1932) one!

But your picture says "7-Shi", doesn't it?!? So is this to say that Wikipedia is right and that your book made a mistake??
I have rarely seen a Japanese publication make a mistake about a national aircraft.

Sure. Here it is. And it does look like it could be a competitor to the MXJ1, indeed.

Actually MXZ1 was only the first type bearing the name Shinryu/Jinryu.

Mizuno later had this very different Shinryu (only a project) which is already discussed elsewhere on this forum (with great profile art by Justo Miranda):

Interesting snippet ! It looks, as if more woman were active in aviation in Japan,
than in the contemorary Germany ! Judging the dresses and look of those scenes,
it probably was a kind of flying club or official organisation ?

The tail reads 大阪 which means Osaka, I can't make out the last character since my Japanese is very poor, but I think it reads something like university. Here is what I found:


‘Japan Student Aviation League’ was established in 1930 fully sponsored by Asahi Newspaper Company. Members at that time were 8 colleges as Hosei, Waseda, Senshu, Keio, Jikei Medical, Meiji, kanto Gakuin, Yokohama. In 1935, glider training was included. After that, Added to the original members, Kansai, Tokai, Tohoku, Kyushu, and Hokkaido Branches are formed and became one of major nationwide students sporting organization. First ‘Student Gliding Competition’ was held at Kirigamine Highland in 1938.


All the activities were suspended due to WWII, and still wait for the restart until 1952 after 7 years of flight prohibition. 20 colleges gathered and organized in 1952 right after the prohibition the became Non-Profit Foundation for glider sports under Ministry of Education in order to promote aviation culture.

Looks like a great book. Too bad there is not an English version.

I will post some information from the book mentioned above.

Ku-11

The Ku-11 was designed by Nihon to compete with Kokusai for a glider capable of carrying 12-18 paratroopers. The project was prepared in 1943 and submitted to the command of the Air Force. In 1944 test flights were conducted on the Ku-11 which demonstrated good performance. However, it was realized that the Ku-11 did not have any real advantage over the Ku-8 by Nihon. This was also combined with the fact Japan was not conducting any landing operations during that time. Nonetheless, 11 units were ordered, perhaps in case the Ku-8 failed. It was never used in combat and only stayed within Japan.

Hi my dear hesham! It's a Mizuno Shinryu(神龍、しんりゅう)special attack glider.

Thanks Hesham. The D-1 was designed by Yoshio Yamazaki, as you say, but the sole D-1 sailplane was built by Itoh Hikoki. So, it is usually referred to as the Itoh D-1:
https://www.j2mcl-planeurs.net/dbj2mcl/planeurs-machines/planeur-fiche_0int.php?code=3454

Wikipedia also assigned the Itoh C-6 to 'Yamasaki Yoshio' (sic). I'm not sure about all the other Itoh glider designs:
http://www.secretprojects.co.uk/forum/index.php/topic,27551.msg285649.html#msg285649

Yoshio Yamazaki is a tough guy to track (in English, anyway). Flight has a 1931 photo of Yamazaki and one of his built sailplane designs:
https://www.flightglobal.com/FlightPDFArchive/1932/1932%20-%200053.PDF

That first Yamazaki glider was later registered J-BESD. There is a poor-quality image in Flugsport 1933:
http://www.atc-ansa.org/aviation-library/database/aviation-military-civil-and-sport-magazine/aviation-1933/index.htm

Yamazaki was also involved in some way with the Japanese version of the German DFS Olympia Meise meant for the 1940 XII Olympiad scheduled for Tokyo:

Ummm.....twin vertical tail stabilizer!! :eek:
According to Ryusuke's Great book"Special attack aircraft and flying bomb of the IJA and the IJN(日本陸海軍の特殊攻撃機と飛行爆弾), ISBN978-4-499-23048-3", Modified Jinryu had twin vertical tail stabilizer.
There is a correct three side view drawing and real side view photo(only No.1 prototype glider) of Jinryu No.1/2 prototype glider with no dihedral angle wing, single vertical tail stabilizer and three rocket boosters based on actual design drawing in Ryusuke's book.
Modified Jinryu's drawing in his book is only side view with no dihedral angle wing, twin vertical tail stabilizer and three rocket booster.


Jinryu replica video. Enjoy.
https://www.youtube.com/watch/?v=h_0AatGg5B4

Attached Jinryu three side view is almost same as actual design drawing, but wing aspect ratio is too large.
Justo-san's wing aspect ratio seems to be good. ;) But wing with dihedral angle is.......I think that high wing does not need dihedral.
