Citizen Tsuyosa Automatic (NJ0151). Current Prices, JDM Listings, Market Analysis

The Citizen Tsuyosa Automatic NJ0151 sits in Citizen's sport-adjacent lineup, a black dial diver-style automatic that has built a steady following among buyers looking for accessible Japanese mechanical watches. Tonbo tracks it because its JDM supply is consistent enough to generate real pricing signal, and the US secondary market shows enough volume to make that signal actionable. With a current US median of $243 and 114 verified comps behind that figure, the NJ0151 price picture is clear enough to work with. For buyers watching the Japan-to-US gap, this is a model worth understanding before moving.

Current US Market Value

The US median for the Citizen Tsuyosa Automatic NJ0151 sits at $243, with the middle 50 percent of sales landing between $210 and $280. That interquartile spread of $70 is relatively tight for a watch at this price point, which tells you the market has found its floor and ceiling with reasonable confidence. The 114-comp sample is large enough to treat those numbers as durable rather than provisional. Comp quality is rated 🟢 Verified, meaning these are real transaction comps pulled from active US listings, not estimates. If you are researching the NJ0151 price for a buy or sell decision, this data is current and grounded.

Recent Alert History

Alert activity on the NJ0151 has been meaningful. Four alerts fired in a tight window around May 24th, split between activity tier and strict tier signals. The strict tier alert is the more conservative signal, requiring tighter margin thresholds before firing. That one landed at $302 all-in with a US median of $377 at the time, producing a 20 percent gross margin estimate. The activity tier alerts were looser, landing between $334 and $343 against the same $377 median, generating margins in the 9 to 11 percent range. That median appears to have since softened to the current $243, so buyers should treat earlier alert data as historical context rather than live guidance.

Japan vs. US Price Gap

At ¥28,000 to ¥31,000 for the typical Japan-side listing, and converting at current rates, the gap to the US median leaves room that has historically attracted resellers and collectors willing to manage import logistics. The NJ0151 for sale in Japan tends to present in better average condition than equivalent US secondary listings, which compresses the condition discount buyers might otherwise apply. The main risk factor worth flagging is the black dial diver profile. Watches in this category attract condition variance at the edges of the comp range, with some listings pushing well above median when described as new and others pulling below when wear on the bezel or bracelet is involved. Comp thinness is not a concern here given the 114-comp sample, but buyers should verify condition specifics carefully before committing.
