This is a purpose built suicide bomb that’s jet powered, much like the V 1's except it had a pilot and the V1 was powered with a pulse jet.
It was carried to a position close to the target by another aircraft such as a Betty then released. The Ohhka pilot would glide until very close, ignite the solid feul rockets (3) propelling it to around 600km/hr in a steep dive to target. The explosive warhead was a repurposed navel shell with hitting a ship in a more vulnerable spot and sinking her in one go. Unfortunately this strategy was easily muted with the carrier planes simply shooting down the Betty's.
A important illustration on the Japanese mind set at the time and the desperation that shouldn't be forgotten.

Not a big kit and I got a lot of it together the first day.

Cheers
Ps ....Glad to be celebrating a birthday
