1. "Omakase" vs "detailed brief"
A traditional Japanese client tends to say "I leave it to you, sensei," a culture of entrusting the designer's aesthetic. An overseas owner, by contrast, is more often the "detailed-brief" type who wants to decide each specification — and this is where the biggest gap appears. Neither is right or wrong; the working assumptions simply differ. The fix is simple: the Japanese side prepares "proposals narrowed to three options," while the overseas side lists in advance the items that are non-negotiable and the items that can be entrusted. That single list turns meetings from "deciding from zero" into "confirming points of agreement," and the two cultures mesh constructively.
2. Specification precision is completion
The spoken "I'd like a whitish floor" is a warning sign. There are dozens of whites, and interpretations differ entirely from person to person. Always specify down to "manufacturer + model number + colour code," and even then line up physical samples on site for a final check — this is the only way to prevent rework. Japanese sites carry an unwritten rule that "anything not decided proceeds at standard specification," and standard specification means whatever is easiest for the builder to choose. In other words, "not deciding" is the same as "letting the other side decide." Treat specification precision as directly equal to the finished quality, and lock it with a three-piece set: drawings, specification, and samples.
3. How to use reference images
An image you cannot convey in words is fastest shared as a picture. But sending a single "nice photo" leaves the other side unsure what to look at. The following approach works.
- 3-5 images per request (line them up along three axes: mood, material, sense of scale)
- Share both "likes" and "dislikes" (the NG list matters more than you'd expect)
- Share a Pinterest board of architectural photos and add intent in comments
- Working with past examples plus photos sharply cuts misreadings of abstract words
Add a one-line note to each image saying what you like (the material, the colour, the size of the opening) and the designer's resolution rises at once.
4. The cultural "yes"
The Japanese "hai" often means "I understood," not necessarily "I agree." Nodding in a meeting is a sign of "I heard you," not approval — and that gap breeds later "you said / I didn't say" disputes. Likewise "I will get back to you" can look like a positive hold yet be a substantive no. The remedy is clear: set a rule at the very first meeting that every important decision is documented and re-confirmed by email asking "is this final as written?" A verbal agreement becomes an agreement only once it is on the record.
5. Minutes as mini-contract
Minutes are not "admin"; they are a "mini-contract." On an overseas project especially, where time zones and languages are crossed, the record is the only shared truth. Run them by these rules and you nip most trouble in the bud.
- Share within 24 hours of each meeting (while memory is fresh)
- Write in three sections: "decisions," "items on hold," "actions before next time"
- Put in the contract a rule that objections must be raised within three business days
- Have both sides treat the minutes as a mini-contract
Always write "who, by when, what" in the action column and dropped tasks disappear.
6. Recording and trilingual notes
Recording a meeting — with the architect's and site agent's permission — lets you replay it later and erases "you said / I didn't say." A recording is the backing for the minutes; it is a mechanism to protect both sides, not to distrust anyone. On a multilingual project the ideal is to keep the minutes side by side in Japanese, English and Chinese, which also surfaces translation drift itself. Using a shared tool that keeps revision history, such as Google Docs, lets you trace when and who changed what, so the history itself becomes evidence.
7. The interpreter you actually need
The quality of interpretation governs the quality of the project. A conversational-level interpreter cannot handle construction and real-estate terms such as "beam depth," "concrete cover," "fixed window," and a mistranslation feeds straight into a specification error. Always arrange a separate "construction and real-estate specialist interpreter." Budget about 50,000-80,000 yen a day. You need not staff every meeting, but it is essential investment for the three "no-going-back" moments: fixing the schematic design, the contract, and the handover. Sharing the drawings and a glossary with the interpreter beforehand raises accuracy further.
A building takes shape through a "game of catch with words." Invest in these three — interpreter, minutes, reference images — and cultural difference turns from the biggest obstacle into your greatest strength: the ability to care about every detail.
