Title: The "Tsubo-tanka" Puzzle: Why You Can't Trust the Unit Price Alone

When comparing builders in Japan, "Tsubo-tanka" (Unit Price per 3.3 sqm) is the most common metric. However, this term is ambiguous.

Depending on the company or even the specific salesperson, the definition changes. One might quote a price for just the "building shell," while another includes insurance and registration fees in their calculation.

You cannot compare apples to oranges. You must ask: "Where does this price stop?"

The "Standard Grade" Trap

Recently, more quotes include basics like curtain rails and air conditioners. However, don't be relieved just yet.

The question is: **"What is the grade?"**

Often, the "standard equipment" is set to a low entry-level grade to keep the initial estimate attractive.

* "Does the kitchen have the dishwasher you wanted?"

* "Is the toilet a modern tankless model, or a basic tank type?"

If you decide to upgrade later (which most people do), the budget will inevitably rise.

At Dwell Japan, we help you check the "Scope" and "Grade" at the initial stage, ensuring your estimated budget matches your actual desires.
