No writing. No hiring.
Yet your articles
keep growing every day.

Hottarakashi Shukyaku is an autonomous marketing SaaS provided by Mugen Kaitaku Co., Ltd. Every day it automatically handles everything from search keyword research to writing, pre-publication checks, publishing and improvements, building up traffic from Google Search and AI search with two articles a day. Our staff handle the initial setup and decide what to do with articles stopped by the checks. Your only task is a 30-minute review each month.

There are three plans based on contract length (all prices excl. tax, 60 articles per month): the 1-year plan at ¥29,800/month (¥357,600 in total, ¥497 per article), the 6-month plan at ¥39,800/month (¥238,800 in total, ¥663 per article) and the 3-month plan at ¥59,800/month (¥179,400 in total, ¥997 per article). The 1-year plan can also be paid monthly (¥29,800/month, ¥32,780 incl. tax). There is no setup fee for lump-sum payment; monthly payment carries a setup fee of ¥30,000 (¥33,000 incl. tax). There is no free trial period. Articles start going out as soon as you sign up.

Just a 30-minute interview and review each month. We handle keyword research, writing, images, posting and revisions.

It takes at least 3–6 months to be found by search engines and AI. We cannot promise rankings or sales. The service suits businesses that plan to keep going over time.

AI writes the body text. Because people do not write each article by hand, we can publish two a day at this price. People handle the initial design (an interview covering target readers, topics, where buttons should lead, which facts may be stated and which words to avoid), revisions during the 30-minute monthly interview, and decisions on articles stopped at the pre-publication check. Articles that do not meet the standard are not published.

Using Google’s search suggestions and Search Console, we prioritize terms people actually search for and write one article per term. Terms proposed by AI are used only when search suggestions confirm that people really search for them. You can request topics and terms in the monthly interview or through our official LINE account, and they are written first. We never write two articles on terms with the same meaning.

Articles are published on a site dedicated to your company, hosted on our servers (a cloud server in Japan). The default address (xx.mugenkaitaku.com) is on our domain. If you want the site to appear on your own domain, you can switch to an address such as media.yourdomain by adding a single line to your DNS settings, and the domain remains yours. Your current website stays as it is.

Google has stated that it does not judge content by whether a person or AI wrote it. What is prohibited is mass-producing thin pages solely to raise search rankings (scaled content abuse). That is why we write one article per search keyword, never mass-produce pages by swapping only place names, and cite information from public bodies as sources. In addition, before publication every article is scanned in full against 59 banned words and 42 check rules to stop overstatements and expressions that may conflict with the law (14 articles have been corrected before publication so far).

We do not refund fees partway through the contract period. Please talk to us if you have special circumstances. When the contract ends and you move to running it in-house, we hand over the article text data and an index (including images), so you can continue on your own site (WordPress, etc.). The articles and images belong to you. If you published on your own domain, you can keep the same address by pointing it to your own server. The site that hosts the articles (the media site) is free to use during the contract period. After the contract ends, you can also purchase that site for ¥200,000 (excl. tax; ¥220,000 incl. tax) (for applications made on or after October 17, 2026).
