Hi!
Incompleted Mizuno type Isuzu glider.(美津濃式 五十鈴グライダー)
Isuzu is a military glider planned by the Imperial Japanese Navy.

In February 1942, Kugisho ordered Mitsuno Glider Manufacturing to design a parallel double seat unlimited aerobatic glider. Kimura Kanichi designed this glider and completed the basic design in June 1942. This glider was named Isuzu. However, the plan was canceled in August of the same year because Kimura engineer was called to the Army.

Hi!
Hikari-shiki type 6.2 glider.(The IJA name Ki-23). Developped from Hikari-shiki type 6.1 glider.

Ki 23 was a military glider prototyped by the Imperial Japanese Army.
Ki 23 was a parallel double-seat glider (soarer) in which the Japanese Imperial Army's Aviation Technology Research Institute placed a prototype order for Fukuda Light Aircraft. Fukuda Light Aircraft produced the internal name "Hikari Type 6.2" designed by Keisuke Ha, Kanichi Kimura, and Mitaka Fujiwara, and the prototype was completed on December 1, 1939. Ki 23 was delivered to the Japan Imperial Army Aviation Technology Research Institute, but was not adopted by the Imperial Japanese Army.
The aircraft of the ki 23 is feathered on a wooden flame, having a semi-embedded single wheel and nasal fistula and tail as a landing device. The towing aircraft used The R-38 prototype training aircraft of Ishikawajima aircraft.
Although Ki 23 was rejected, the light type 6.2 type of private specification was used for glide training at the Dainippon Flight Association. The price of the private type is 6,000 yen per machine. In 1942, the Navy also purchased the light 6.2 type of two aircraft manufactured by Mizuno Glider Manufacturing Co., Ltd. as a candidate for a training glider for the crew of a 16-shi special transport aircraft, and was examined at Kasumigaura Airfield, but it rejected as a cause of lack of speed and vibration of the main wing.

Specifications
Length: 7.6 m
Wingspan: 17.0 m
Wing area: 21.0 m2
Empty Weight: 276 kg
Gross Weight: 426 kg
Best glide speed: 70.3 km/h
Crew: 2

Hi!
Maeda-shiki type-5 Tamaya-go(玉屋号) soarer.
Completed in 1935. This glider was a development type of Kyutei type-5.
This was the firsr glider in Kyushu which towed by the aircraft, but no flight record.
Tamaya is the name of the department store in Fukuoka Kyushu. Tamaya was the sponcer(スポンサー) of this glider.

I am looking for any information about the Japanese military gliders Fukuda Ku-5 and Ku-12 (Hikari 6.3).

Hi!
The Ku-5 is a glider (military glider) prototyped by the Imperial Japanese Army.
During World War II, Maeda Koken Kogyo Co., Ltd. developed the Ku-5 as a gliding aircraft used by the Army for practice training. The aircraft had a shape similar to that of a light aircraft at the time, except that it did not have an engine, and it was a tandem tri-seat low-wing monoplane. The landing gear was a fixed type. Development was stopped only after the prototype was manufactured.

The Ku-12 is a glider (military glider) prototyped by the Imperial Japanese Army. Developed by Fukuda Light Airplane.
In January 1943 (Showa 18), the Imperial Japanese Army Air Force Headquarters established "Army Air Weapons Research and Prototype Policy" (new research policy), and developed a training glider by March 1944. However, the goal was to complete the examination. Ku-12 was developed by Fukuda as an intermediate-level glider for automobile towing, and although the prototype was manufactured, it was not adopted, and a small number of aircraft were called "light type 6.3" and used by the private sector.
The fuselage was Japan's first double-seater intermediate-level glider, and the fuselage had only a frame, and the nacelle was attached to the first half.
The seat layout was a tandem type with the rear seat inside the fuselage. The main wing was a half-cantilever taper wing.
• Total length: 7.0 m
• Overall width: 14.0 m
• Weight: 180 kg
• Total weight: 320 kg(too heavy?)
• Glide speed: 55-65 km / h
• Crew: 2 people

I'm trying to find pictures and drawings of these gliders. It's hard. Give me time.
