How guidance is made
Methodology
Use this method when choosing between a Japan camera offer and a home-market offer. Match the equipment and support you need, calculate the complete costs, then decide whether the saving is worthwhile.
1. Make the quotes comparable
For each offer, record the seller, quote date, exact model code, market version and body-only or lens-kit configuration. List the included battery, charger and accessories you need. Add a real replacement quote for anything missing.
- Condition: distinguish new, used and items sold with faults. Record disclosed defects and inspection results separately from the seller's cosmetic grade.
- Market version: check the exact unit's required menu language and specifications. A familiar model name alone does not settle this.
- Support: record who handles warranty service, where the item must be sent, and the return conditions for this purchase. Keep the written answer with the quote.
2. Compare the complete payable cost
The camera calculator uses your inputs: Japan quote × home-currency units per yen × (1 + separate payment-fee percentage ÷ 100) + other costs in your home currency. If your rate is quoted as yen per home-currency unit, the calculator converts it to the reciprocal first.
Use the actual amount you would pay and the same currency for all home-currency fields. If the rate already includes a fee, enter zero for that same fee. Include required accessories, purchase-specific travel or delivery, and any confirmed destination charges. Keep unconfirmed costs in your notes; entering zero would conceal them. Do not deduct an assumed tax refund.
Keep condition, compatibility and acceptable support beside the price difference when you make the decision.
Worked example: a saving with an unresolved requirement
Illustrative example only. All amounts, quotes and circumstances below are fictional. They are not current prices, exchange rates or retailer terms.
Suppose two body-only offers match the exact model, new condition and required accessories. The Japan quote is ¥100,000. At an illustrative rate of 0.0067 home-currency units per yen, a separate 2% payment fee and 20 in other costs, the total is 703.40. A home quote of 750 leaves a provisional saving of 46.60.
Any additional cost above 46.60 removes the saving. If the Japan unit's required menu language or service coverage at home is still unknown, pause the purchase even while the arithmetic looks favourable. Next, test the actual unit and obtain the applicable written support terms, then recalculate with any new costs.
3. Match each claim to the right source
- Product specifications: use the maker's documentation for the exact model and market version, then verify the required function on the unit when possible.
- Sale and support terms: use the selling shop's applicable terms and item-specific written quote. A general policy cannot fill a gap in a particular used item's description.
- Tax procedures: use the responsible public authority for the purchase date and the shop for its transaction process. Follow the links in Current Buying Notes.
The Research Log records source checks and their dates. We prefer an applicable, dated primary source over an undated summary. If sources conflict or the specific version is missing, retain the uncertainty and seek a more specific answer.
4. Recheck what could change the decision
Keep essential unanswered questions marked unknown. Warranty, condition and language need specific answers; assigning them invented cash values would hide the difference between the offers.
Recheck a quote when it expires or the payment rate changes, and recheck shop notices before a special trip. At the counter, confirm the unit, contents, condition, final charge and written return or service terms again. An earlier source check cannot establish today's stock or the condition of the camera in your hands.
Set a minimum worthwhile saving before adding another shop. If an essential requirement stays unknown, choose a confirmed alternative or wait. A source review is not a firsthand visit; historical photographs and illustrations keep their own labels under our editorial standards.
Use the method on your own offers
Follow the full quote-comparison worksheet, check a used camera, or record two options and shop questions in your fieldbook. Once the inputs are comparable, calculate the price difference.
