The Staged Roadmap

From e-books to collected editions, audio and the digital library

段階的ロードマップ構想

The Plan

First, finish everything that can go out as e-books. After that, move the effort stage by stage: to the ten thousand manuscripts, to paper collected editions series by series, and to audio. The destination is 11 December 2042, when the digital library opens and all ten thousand books appear at once, as text and as audio. This plan puts the other three — the New Ten-Thousand-Volume Plan, the Digital Library Plan and the AI Autonomous Operations System — into the order in which they will happen.

The Premise — Kindle's New Rule

From 21 September 2026, KDP allows two new titles per format per week. The weekly allowance resets every Sunday at 00:00 UTC. Japanese and English editions both count as e-books. It has been reported that the old help-page invitation to ask for an exception, for authors who create many titles, disappeared at the same time.

From 27 September 2026 to 11 December 2042　　　846 weeks E-books Kindle can take (Japanese and English)　　1,692 Share of the ten thousand　　　　　　　　　　　　about 17% Opened in the digital library from the start　　　about 8,300

Where the 10,000 go　In the end, every book opens in the digital library, as text and as audio.

Five Stages

1　Finish the e-books 　　When (at the current pace): October 2026 to about June 2027 　　Prepare first the 1,692 books that fill the Kindle allowance up to 2042. After that, Kindle simply releases the stock, two a week.

2　Focus on the ten thousand manuscripts 　　When: 2027 to about 2031 　　Concentrate on manuscripts written for the library, free of store limits.

3　Turn them into audio 　　When: pilot from late 2026; full scale in the 2030s 　　An automatic flow with a reading dictionary and a synthetic voice, so that each finished book gets its audio.

4　Paper collected editions 　　When: 11 December 2027 / around 2030 / 11 December 2042 　　Released at milestones, starting with the series already complete.

5　The opening 　　When: 11 December 2042 　　Text and audio open at once.

The five stages　Dates are for the current pace. A slower pace moves stages 1 and 2 later.

When It Is Ready — Three Slower Paces

As of 24 September 2026, 282 books exist in Japanese and English together, 121 are published, and about 160 are bound and waiting to be submitted. Over the last three weeks the pace has been about 43 books a week. Taking that as the base, three plans slow it to three quarters, a half and a quarter.

Pace　　　　　　　　　Kindle allowance filled　　10,000 manuscripts complete Current (~43/week)　　June 2027　　　　　　　　　February 2031 A 3/4 (~32/week)　　　August 2027　　　　　　　　July 2032 B 1/2 (~21/week)　　　February 2028　　　　　　　June 2035 C 1/4 (~11/week)　　　June 2029　　　　　　　　　March 2044

When everything is ready　At any pace, the Kindle allowance fills within a few years. To have all ten thousand by 11 December 2042 needs at least about 11.5 books a week. If the rule went back to ten a week, the allowance would be 8,460 books, filled in June 2030 at the current pace and in March 2034 under plan B.

Paper Collected Editions

Not sets of five separate titles, but a collected edition for each series, with each four-part work (about 400,000 Japanese characters) in two volumes. The paperback allowance is a separate two a week, so there is no shortage of slots. Hardcovers cannot be published through the Japanese KDP, so the paper editions are paperbacks.

11 December 2027　The series already complete 　　　　　　　　　Mugen Uchūtan, Mugen Yūgi, Golden Seeds, essays and poems Around 2030　　　　As each Black Swan series completes 　　　　　　　　　The Cosmology of the Spherical Temple, the Tellers, G-SHOUWA-Ω, CHRONOS, Tensou Kairou 11 December 2042　A complete memorial edition (including Japanese-English bilingual volumes)

A Library to Listen To

No ordinary reader can read ten thousand books by eye. The ten thousand include both Japanese and English, so one listener hears one language: about five thousand books, some 27,500 hours at normal speed. At double speed, two hours a day, that takes about nineteen years; at triple speed, about thirteen. By ear, they fit within a lifetime.

　　　　　2 hours a day　　3 hours a day 1x　　　　38 years　　　　 25 years 2x　　　　19 years　　　　 13 years 3x　　　　13 years　　　　 8 years

Reading 10,000 books by listening　Counted as about 100,000 Japanese characters per book (about 5.5 hours at 300 characters a minute) or about 45,000 English words (about 5 hours at 150 words a minute).

The main stores do not yet offer synthetic narration in Japanese. So the library makes and delivers its own audio. When a manuscript is finished, the text is divided into chapters and paragraphs, a reading dictionary is applied, a synthetic voice reads it, the volume is levelled, chapter markers are added, and the result goes into the library. This flow becomes one stage of the AI Autonomous Operations System. PEGIS works are full of coined words and proper names, so the reading dictionary is the heart of the quality. The voice is made a little slow so that it stays clear at double speed, and playback can be set from 1x to 3x. Even fifty thousand hours of audio need only about 1.5 terabytes.

Some English editions can also go out through the stores' synthetic-voice routes (an invitation to Kindle's Virtual Voice, and Google Play's auto-narration). For selected works, an audio edition layered with the music of the Kotodama Orchestral Symphony will be made.

11 December 2042

The digital library opens, and all ten thousand books appear at once, as text and as audio. Each book is a fragment of the stage set of the 2042 installation, Dai-Tenji-Kai. Ten thousand is not a sales figure but a presence.
