The Sweet Home Strategy Guide and Gamebook
One official strategy guide, one gamebook, both from Futabasha, both printed within weeks of the game.
Yes, Japanese guides exist, and they are better documented than most of the game's Western coverage suggests. Futabasha, the era's Famicom strategy specialists, published the game's official strategy volume in January 1990, and a gamebook besides. For a Japan-only title, the paper record is unusually complete.
This page exists because the guides are part of the object. A collector who finds the cartridge has found half the publication. The other half is here.
THE SHELF
Two books and a manualThe strategy guide · January 12, 1990
Sweet Home Hissho Koryakuho, the sure-win strategy guide, published by Futabasha and edited by the Fighting Studio team, ISBN 4-575-15154-8. It appeared four weeks after the game, the era's standard rush for a title expected to stump its players, which a permadeath mansion RPG certainly did.
The gamebook
Futabasha also published a Sweet Home gamebook, Masho no Sumu Yakata (The House Where Evil Dwells), by Katsuyuki Ozaki: a choose-your-path paperback that retells the mansion as solo interactive fiction. A game most publishers would treat as a licence footnote got two books.
The manual as a guide
Capcom's own 40-page manual closes with two pages of playing tips, and fan archivists have published a full scan and transcription with an English translation, the closest thing to an official English guide that will ever exist.
THE PAPER TODAY
Japan-only game, Japan-only paperPriced like the game
Used copies of the Futabasha guide surface in Japanese bookshops at prices in the game's own range: listings checked in November 2026 asked 4,410 and 5,292 yen, tax included. Thirty-six years on, the walkthrough costs about what a loose cartridge does.
Why it matters
A Japan-only game leaves a Japan-only paper trail. The guide and gamebook are primary sources for how Sweet Home was presented to its first players, maps, art, and all, and no equivalent was ever printed in English.
