Orient Kamasu (2018-) (Kamasu, RA-AA0001B19B). Current Prices, JDM Listings, Market Analysis
The Orient Kamasu is a dive-style watch released by Orient starting in 2018, carrying reference numbers Kamasu and RA-AA0001B19B. It sits in the accessible end of the Orient lineup and draws consistent interest from buyers looking for a well-finished Japanese automatic at a modest price point. Tonbo tracks the Kamasu price because JDM sourcing opportunities surface regularly, and the US-Japan spread can justify the effort for buyers who know what to look for. At the moment the US market is sitting in a narrow, stable band just under the $300 mark.
Current US Market Value
The current US median for the Orient Kamasu (2018-) Kamasu sits at $287, with the middle half of transactions landing between $271 and $303. That is a tight interquartile range, which suggests pricing is relatively consistent rather than volatile. It is worth noting that this figure is drawn from a sample size of two verified eBay transactions, classified as 🟢 Verified comps. Two data points establish a directional signal, but they do not carry the same statistical weight as a deeper sample. Treat the $287 median as a reasonable anchor for now, and expect it to sharpen as more transactions are recorded. Anyone researching Kamasu for sale in the US should use this range as a baseline against which to judge individual listings.
Active JDM Listings
Japan is showing a wide range of active pricing right now, which is typical for a model that appears across both flea market platforms and shop aggregators. The lowest recent listing came in well under ¥20,000 on Yahoo Flea, while several shop listings are priced significantly higher. That spread almost certainly reflects condition differences and seller type rather than any single coherent market price. Buyers looking to buy Kamasu Japan should pay close attention to platform context here.
- ¥10,450 listed on Yahoo Shop (condition unknown)
- ¥19,800 listed on Yahoo Flea, noted as having no noticeable scratches or stains
- ¥83,090 listed on Yahoo Shop (condition unknown)
- ¥118,700 listed on Yahoo Shop (condition unknown)
- ¥151,690 listed on Yahoo Shop (condition unknown)
The ¥19,800 flea market listing with a clean condition note is the most immediately interesting data point for arbitrage purposes. The cluster of higher shop listings likely includes new or near-new stock, boxed sets, or limited variants, though condition details were not available at time of scrape.
Recent Alert History
No strict or opportunity alerts have fired for the Orient Kamasu (2018-) in the past 90 days. That is an honest read of the data rather than a gap in coverage. It means no JDM listing has cleared the threshold required to flag a meaningful price dislocation relative to the US market during that window. This can change quickly when a clean flea market unit surfaces at a low enough ask. Monitoring the Tonbo signals feed is the most reliable way to catch those moments without manually checking Japanese platforms daily.
Japan vs. US Price Gap
The US-Japan price gap on a model like the Orient Kamasu (2018-) Kamasu is driven primarily by the friction of JDM sourcing rather than any fundamental scarcity. Buyers in the US generally pay a convenience premium, and that premium tends to compress the spread for widely available models. When a used unit surfaces on Yahoo Flea at ¥19,800 or less with a clean condition report, the math can work, but shipping, proxy fees, and import considerations eat into the margin quickly. The main risk here is condition variance combined with thin US comps. With only two verified US transactions on record, a single outlier listing could skew perceived value in either direction, so buyers should cross-reference against current live US listings before committing. The Tonbo deals tracker surfaces cases where the spread has historically been wide enough to act on.
