next-tokushoho

Drop-in 特定商取引法に基づく表記 (Tokushoho) page generator for Next.js. Stripe-審査-pass ready, bilingual JP/EN, zero styling lock-in.

What

If you're a Japan-based indie hacker selling SaaS via Stripe, you need a 特定商取引法に基づく表記 page. Otherwise:

• Stripe rejects your account
• Your credit card processor pulls you off
• Customers can't legally identify you

Writing this page from scratch is annoying, easy to under-include fields, and gets nitpicked by Stripe support. next-tokushoho is a battle-tested template, extracted from production Kyren products that passed Stripe audit.

Features

• ✅ All 14 fields required by 特定商取引法 §11 + Stripe-審査 additional asks
• ✅ Bilingual JP / EN / both (Stripe要件は JP 必須)
• ✅ "Address on request" pattern for indie hackers (Stripe-accepted)
• ✅ Subscription / one-time / free pricing modes
• ✅ Refund policy presets (7-day, 14-day, none, custom)
• ✅ Zero CSS dependency — pure inline styles, override via classNames prop
• ✅ TypeScript-first, fully typed config
• ✅ React 19 / Next.js App Router compatible

Install

npm install next-tokushoho
# or
pnpm add next-tokushoho
# or
bun add next-tokushoho

Usage (Next.js App Router)

app/tokushoho/page.tsx:

import { Tokushoho, type TokushohoConfig } from "next-tokushoho";

const config: TokushohoConfig = {
  productName: "MyApp",
  seller: { name: "山田 太郎", representative: "山田 太郎" },
  contact: {
    email: "support@example.com",
    address: "on_request",
    phone: "on_request",
  },
  pricing: {
    type: "subscription",
    tiers: [{ name: "Pro", priceJpy: 500, interval: "monthly" }],
  },
  payment: { methods: ["credit_card"], processor: "Stripe" },
  cancellation: { inApp: true },
  refund: { policy: "7days_full" },
  lastUpdated: "2026-04-28",
  locale: "ja",
};

export default function TokushohoPage() {
  return <Tokushoho config={config} />;
}

export const metadata = {
  title: "特定商取引法に基づく表記 | MyApp",
};

That's it. The component renders all 14 required rows with sensible defaults pulled from your config.

Tailwind / custom styling

The component ships with minimal inline styles. To restyle, pass classNames:

<Tokushoho
  config={{
    ...config,
    classNames: {
      root: "max-w-3xl mx-auto px-6 py-12",
      title: "text-3xl font-bold mb-2",
      lastUpdated: "text-sm text-gray-500 mb-8",
      table: "w-full border-collapse",
      row: "border-b border-gray-200",
      th: "text-left py-4 pr-4 font-medium align-top w-1/3",
      td: "py-4 text-gray-700",
    },
  }}
/>

Configuration

See src/types.ts for the full type. Key options:

payment.methods	("credit_card" | "bank_transfer" | "convenience_store")[]
payment.processor	string	e.g. "Stripe"
cancellation.inApp	boolean	true → 「設定画面から解約」
refund.policy	"7days_full" | "14days_full" | "none" | "custom"	7days = Stripe-friendly
locale	"ja" | "en" | "both"	JP required for compliance

Stripe-審査 checklist (battle-tested)

Real audit asks Stripe sent us, and how this template handles each:

• 販売業者: full legal/personal name. Anonymous handles rejected.
• 代表者名: same as seller for sole proprietorships.
• 所在地: on_request accepted as long as the disclosure is clear and SLA stated.
• 電話番号: on_request accepted, same caveat.
• メールアドレス: must be reachable.
• 販売価格: tax-inclusive, JPY, all tiers listed.
• 販売価格以外の必要料金: explicit (internet/comm fees).
• 支払方法: methods + processor.
• 支払時期: subscription auto-renew clearly stated.
• サービス提供時期: instant for digital.
• 契約期間: auto-renewal terms.
• 解約方法: in-app with billing-period-end clarity.
• 返品・キャンセル: 7-day full refund preset is the easiest审查通过 path.
• 動作環境: modern browsers list.
