What is for sale

This is a small luxury diamond jewelry sales business based in Tokyo, sold mainly through in-person, made-to-order transactions with an accompanying but lightly-used e-commerce site. The owner has run it alone as a side business, earning around ¥600,000 in profit some months from just a handful of high-ticket sales, and is selling because their other work has become too busy to continue running it.

The listing does not clearly state whether this is a share sale or an asset sale, so a buyer should confirm directly with the seller whether the company entity, or just the business assets/stock, will transfer.

What is included

Some existing jewelry stock
E-commerce site (transferable, though underused)
Repeat customer relationships/introductions
Made-to-order production process (no upfront inventory cost model)

Strengths (as the seller states them)

High unit prices mean just a few sales per month can generate meaningful profit
Made-to-order model means little upfront cost or inventory risk
Has a base of repeat customers the seller will introduce to the buyer
Simple, low-overhead operation suitable for solo or side-business management

Wrinkles a careful buyer would ask about

Almost all sales happen in person, not via the e-commerce site, so buyers should check how much the online store actually contributes
Financials are thin/undisclosed in detail — only broad revenue and profit ranges are shown, not confirmed net asset or profit figures
Buyer should clarify exact scope of inventory being transferred
Extent of repeat-customer handover is not fully detailed and should be confirmed in negotiation
Transfer type (share vs. asset) is not explicitly stated, so business structure and any liabilities need to be clarified with the seller

Paying for it

If you stay overseas. No Japanese bank will lend to a new company whose director lives abroad. The realistic stack is your own cash plus asking the owner to take part of the price over 2 to 3 years. That one question is in every Deal Pack.

If you move to Japan. On a visa that lets you run a business, Japan Finance Corporation lends up to ¥72M at about 1 to 2 percent for exactly this. Once you have a Japanese company, the government pays two-thirds of due diligence and registered-broker costs, up to about ¥8M (round 16 closes 6 Nov 2026).
