| Business | Planning, development, operation, and sale of my own software; custom software development; and the operation of a partner program |
| Price, payment, delivery, and returns | The price, payment methods, delivery timing, and return conditions for each service follow the terms shown on that product’s own site or inside the app. |
| Free first-build conditions | Choose either a website or a landing page + video for your free first build. Publication on a free subdomain is required, once per customer with 30 places in total. You can add the other service at its regular price. Only one of the two services can receive the free offer. Duplicate applications by the same business or operator under another name or email address are charged at the regular price. Eligibility is checked after the enquiry; submitting an enquiry does not confirm the free offer. A phone number is required for this check. |
| Regular website, landing-page, and video prices | Regular website production starts at JPY 11,000, tax included. Landing-page production: JPY 4,400 per page, tax included. Video production: JPY 5,500 per video, tax included. A landing page + video costs JPY 9,900, the combined individual prices including tax. For example, an eligible JPY 0 website can be combined with a paid landing page + video for JPY 9,900. Content, video duration, revision scope, and the final total are confirmed before work starts. Additional features are charged separately; external costs such as custom domains are billed separately at cost. |
| Ongoing marketing support pricing and availability | JPY 16,500/month, tax included. Monthly plan — preparing for launch. Support that continues after launch, reviewing your intended customers and the response each week. It includes landing-page and video production and improvements, plus weekly reports. Separate from one-off production and the free first-build campaign. Automated improvements and switching where ads run are not yet available. Readiness and service terms will be confirmed before this plan opens for orders. Summaries cover the weekly review and proposed next improvements. A weekly review does not mean a new landing page or video is produced every week. Optional one-time setup service: JPY 11,000, tax included. No setup-service fee applies if you complete the initial setup yourself. The monthly fee still applies. Connection instructions will be provided before the plan opens for orders. I suggest a budget, but you decide the amount and whether to run or change ads. Advertising spend is not included in the monthly fee. Monthly and setup-service fees are not part of the free first-build campaign. Monthly production quantities, video duration, revision counts, advertising-channel counts, the scope of human assistance, contract length, and cancellation terms will be confirmed before orders open. Production and revisions are not unlimited. Search rankings and customer acquisition results are not guaranteed. |
