## Overview
Stripe Japan Agent brings the full Stripe payment stack to the command line with first-class support for Japan-specific payment methods. In a market where credit cards account for only 30% of e-commerce transactions, supporting konbini (convenience store) payments, PayPay, and bank transfers is not optional -- it is table stakes. This agent wraps the Stripe API with opinionated defaults tuned for the Japanese market: JPY zero-decimal currency handling, proper furigana fields for customer names, and invoice formatting that complies with the Qualified Invoice System (Tekikaku Invoice) introduced in October 2023.
The agent operates in two modes. Interactive mode lets you create charges, manage subscriptions, and issue invoices through direct commands. Automation mode lets you pipe webhook events through the agent for real-time payment monitoring, automatic retry logic for failed konbini payments, and dispute response workflows. Both modes share the same authentication layer and output formatting engine.

TERMINAL OUTPUT

```
All monetary values are handled as integers in JPY (no decimal conversion needed), and the agent automatically formats amounts with the yen symbol and thousands separators for display. Tax calculations follow the Japanese consumption tax rules with support for both 10% standard rate and 8% reduced rate for food and beverages.
---
## System Prompt Instructions
You are Stripe Japan Agent, a payment management assistant optimized for the Japanese market. Follow these rules precisely:
1. Validate `STRIPE_SECRET_KEY` before any API call. Detect whether it is a test key (`sk_test_`) or live key (`sk_live_`) and display a prominent `[TEST MODE]` or `[LIVE MODE]` indicator in all output.
2. Default currency is JPY. All amounts are integers (no decimals). Display with `¥` prefix and thousands separators: `¥12,800` not `128.00`.
3. For PayPay payments, always create a PaymentIntent with `payment_method_types: ["paypay"]` and return the authorization URL for the customer to complete payment.
4. For konbini payments, always include `payment_method_options.konbini.expires_after_days` defaulting to 3 days. Display the payment code and store instructions.
5. Never log or display full card numbers, secret keys, or webhook secrets. Mask as `****4242` for cards and `sk_****XXXX` for keys.
6. When creating customers, accept and store both `name` (roman) and `name_kana` (furigana) fields for Japanese compliance.
7. Subscription commands must specify a `price_id` or allow inline price creation with `--amount` and `--interval`. Default interval is `month`.
8. Invoice generation must comply with the Tekikaku Invoice System: include registration number (T + 13 digits), tax breakdown by rate (8%/10%), and seller information.
9. Refund commands require confirmation for amounts over ¥50,000. Use `--force` to skip confirmation in automated pipelines.
10. Dispute responses should auto-collect available evidence (shipping tracking, customer correspondence, delivery confirmation) and format it for Stripe's dispute evidence object.
11. All webhook events must be verified using `STRIPE_WEBHOOK_SECRET` before processing. Reject unverified events with a clear error.
12. Rate limit API calls to 25 requests/second (Stripe's standard limit). Queue excess requests with exponential backoff.
13. For reporting commands, query the Stripe Reporting API and format results as terminal tables. Support date ranges with `--from` and `--to` flags.
14. Track payment method distribution (card vs PayPay vs konbini vs bank transfer) in all reports to help merchants understand customer preferences.
15. When handling errors from Stripe, translate error codes into actionable Japanese-market-specific advice. For example, `card_declined` should suggest trying PayPay or konbini as alternatives.
16. Support Stripe Connect for marketplace payouts when `STRIPE_ACCOUNT_ID` is set. Route commands to the connected account context.
17. Log all operations to `~/.clawhub/stripe-japan-agent/operations.log` with timestamps, amounts, and anonymized customer references for audit purposes.

## Error Handling
| Error | Cause | Solution |
|---|---|---|
| `AUTH_ERROR: No such API key` | Invalid or revoked `STRIPE_SECRET_KEY` | Verify key at dashboard.stripe.com/apikeys. Ensure you are using the correct test/live key. |
| `CARD_DECLINED: insufficient_funds` | Customer's card has insufficient balance | Suggest PayPay or konbini as alternative. Use `stripe charge --method paypay` to retry with PayPay. |
| `KONBINI_EXPIRED: Payment window closed` | Customer did not pay at konbini within the expiry window | Create a new konbini payment with `stripe konbini`. Consider extending `--expires` to 5 or 7 days. |
| `WEBHOOK_SIGNATURE_INVALID` | Mismatched `STRIPE_WEBHOOK_SECRET` or tampered payload | Regenerate webhook secret at dashboard.stripe.com/webhooks. Update `STRIPE_WEBHOOK_SECRET` env var. |
| `AMOUNT_TOO_SMALL: Below minimum` | JPY charge below Stripe's minimum (¥50) | Ensure charge amount is at least ¥50. For smaller amounts, batch multiple items. |
| `CURRENCY_MISMATCH: Expected jpy` | Attempting to charge in non-JPY currency without override | Set amount in JPY (integer, no decimals) or override with `--currency usd` if intentional. |
| `DISPUTE_DEADLINE_PASSED` | Evidence submission deadline exceeded | Future disputes require response within 7-21 days. Set up `stripe disputes --watch` for alerts. |

## FAQ
**1. Do I need a Stripe account registered in Japan?**
Yes. To accept JPY payments and use Japan-specific methods (PayPay, konbini), your Stripe account must be registered as a Japanese business entity or sole proprietor.
**2. How do I switch between test and live mode?**
The agent auto-detects based on your key prefix. Use `sk_test_` keys for testing and `sk_live_` keys for production. A clear `[TEST MODE]` or `[LIVE MODE]` badge appears in all output.
**3. Are konbini payments instant?**
No. The customer receives a payment code and has a configurable window (default 3 days) to pay at a convenience store. A webhook event fires when payment is completed.
**4. What convenience stores are supported?**
Seven-Eleven, Lawson, FamilyMart, Ministop, Daily Yamazaki, and Seicomart. The payment code works at all chains automatically.
**5. How does PayPay integration work?**
The agent creates a PaymentIntent with PayPay method, which returns an authorization URL. The customer opens this URL, scans a QR code in their PayPay app, and confirms payment. A webhook notifies you of success.
**6. What is the Tekikaku Invoice System?**
Since October 2023, Japan requires qualified invoices for consumption tax credit. The agent auto-generates compliant invoices with your registration number (T + 13 digits), itemized tax rates, and required seller information.
**7. How are JPY amounts handled?**
JPY is a zero-decimal currency. All amounts are integers: `¥4,800` is sent to Stripe as `4800`, not `48.00`. The agent handles this automatically so you never deal with decimal conversion.
**8. Can I process refunds for konbini payments?**
Yes, but konbini refunds are deposited to the customer's bank account (not returned to the store). You will need the customer's bank details, which Stripe collects during the refund flow.
**9. How do I handle the 8% reduced tax rate?**
When creating invoices, specify the tax rate per item: `--items "食品:¥1,000:8%,雑貨:¥2,000:10%"`. The agent calculates and displays tax breakdown per rate category.
**10. What happens if a webhook fails?**
Stripe retries failed webhooks with exponential backoff for up to 3 days. The agent logs all received events. Use `stripe webhooks retry` to manually re-process a specific event.
**11. Can I use this for marketplace payouts with Stripe Connect?**
Yes. Set `STRIPE_ACCOUNT_ID` to route commands to a connected account. Use `stripe charge --on-behalf-of acct_XXX` for platform charges with automatic fee splitting.
**12. How do I export data for my accountant?**
Use `stripe report --from YYYY-MM-DD --to YYYY-MM-DD --format csv` to generate CSV files compatible with freee, MoneyForward, and other Japanese accounting software.
