The 56th Shinbu Unit
The paper called "volunteering" — on the special attack unit Uehara Ryoji belonged to

This page is not here to tell a unit's battle history. Behind one man's last writing (Uehara Ryoji's "Thoughts"), there was another sheet of paper — the form called "volunteering," which made him a "special attack pilot." This page exists so that this paper, and a human being's words, can be seen side by side.

Why was this unit at Chiran?

Uehara Ryoji flew out over the sea toward Okinawa from the army airfield at Chiran, Kagoshima, as a member of the 56th Shinbu Unit.

Why did a Keio student who loved reading Croce fly a bomb-laden aircraft into a ramming attack? Not because he wished it. Another sheet of paper — an institutional paper that assigns a person the status of "special attack pilot" — carried him there.

What were the Shinbu units? 🟢 Confirmed

• Shinbu units were the special attack units (aircraft units for ramming attacks) organized under the army's 6th Air Army for the Battle of Okinawa, which began on 26 March 1945. Each unit carried its own number; Uehara's was the 56th.
• The sorties centered on the army airfields at Chiran and Bansei, in Kagoshima. The Tomiya diner — where Uehara murmured to its proprietress, Torihama Tome, "Ma'am, Japan is going to lose" — stood in this Chiran.
• The pilots were young men in their late teens and early twenties: army youth pilots, called-up NCOs, and reserve officers like Uehara who had come through the special flight officer trainee program. Most were around twenty years old.

The other sheet of paper — the form called "volunteering" 🟢 Confirmed

To think about this unit, one sheet of paper matters most: the paper that records how the pilots were chosen.

The method differed from unit to unit. Among those on record: skilled pilots were pre-selected, the commander gave an address, and each man was called into a room to confirm his intent. Or: a signed ballot with three choices — "Fervently wish / Wish / Do not wish." Or: the whole unit was assembled, the call was proclaimed, and volunteers were told to step forward.

On paper, every one of these is "volunteering." But standing before a ballot that bears your name, with superiors and comrades watching — how many men could write "Do not wish"? When Uehara went home on leave, he let this slip to a close friend: "They create a situation in which you cannot help but raise your hand." What he had seen was exactly this mechanism — the paper called "volunteering."

In his "Thoughts," Uehara wrote of himself as "no more than a machine" — "a machine that grips the control stick, without personality, without feeling." The institutional paper that sends people off as machines; and the human paper that wrote, "but once I step down from the plane, I am a human being after all — there is feeling there, and passion stirs." These two sheets faced each other on the same airfield at Chiran.

Sources: selection methods for Shinbu pilots (commander's address; individual confirmation of intent; signed ballot "Fervently wish / Wish / Do not wish"; proclamation with volunteers stepping forward) — verified in 2026 against primary sources. Uehara's remark to his friend and the "machine" passages of the "Thoughts": episode scripts / provenance. ⚠️ Which selection method applied to Uehara himself is unverified (it differed by unit; we do not assert).

Fragments of this unit

• The one fragment of this unit that can be read with certainty today is Uehara Ryoji's "Thoughts" — a rare sheet in which a special attack pilot observes himself as "no more than a machine," and still closes, "my heart is full of contentment."
• Many last letters and wills of the young men who flew from Chiran also survive. One by one, as they are verified, they may join this page.
