These terms set out the rules that apply when you play “Sakai Merchant's Diary” (the “Game”).
By starting to play the Game, you are deemed to have agreed to these terms.
If you do not agree, please stop playing.
The Game is a single-player game set in Sakai from the end of the Sengoku period to the beginning of the Edo period (1560–1620), in which you grow a small shop over sixty years. No registration is required to play.
The story is fiction. Although it is based on history, its depictions of characters, shops, and events include invented material. It does not accurately convey historical fact.
Where the names of real people appear, they are used for storytelling purposes only and have no connection with those people, their descendants, or any related organizations.
Modifying the Game without permission and distributing it in an illegitimate form (such as a version that falsifies records or one that harms users).
Analyzing the program and redistributing or selling it, as is or modified, without the author’s permission.
Causing trouble for others, or placing an unreasonable load on the distribution systems.
Any other conduct that violates the law or public order.
All rights to the text, design, program, and images of the Game belong to the author.
Some images were created with generative AI and then modified by the author.
Bundled open-source software is subject to its respective license terms. Please see the Licenses page.
In the app version, ads may be shown at breaks in play (such as after an ending). Ads do not affect the outcome or progress of play.
“Remove Ads” is a one-time purchase. Purchasing it does not change your shop’s strength or your staff’s abilities.
Purchases, refunds, and cancellations are subject to the terms of each store (such as Google Play). The author does not promise refunds on an individual basis.
Your shop’s strength, the abilities of your apprentices and head clerks, and endings cannot be bought with money or ads.
Saved data may be lost due to the circumstances of your device or browser. We recommend exporting it with “Backup of records” in Settings.
The Game is provided as is. We cannot promise that it will always work correctly.
To the extent permitted by law, the author is not liable for any damages arising from playing the Game.
The contents of the Game may be changed without notice. The Game may also be withdrawn from publication.
We will try to give notice as early as possible.
These terms are governed by the laws of Japan.
Any disputes will be resolved in the courts of Japan.
These terms will be revised as necessary.
