Sushi Restaurant
$155T base cost · $219M/sec
Business Overview
Rolling in it.
Few businesses reward patient reinvestment quite like the Sushi Restaurant — buy copies steadily and the income compounds fast.
Cost Scaling
Every business in Tycoon Cards uses the same cost curve: each copy costs 15% more than the last. For the Sushi Restaurant, that looks like this:
| Copies owned | Cost of next copy | Total spent to reach this many |
|---|---|---|
| 1 | $179T | $155T |
| 10 | $629T | $3.16Qa |
| 25 | $5.12Qa | $33.1Qa |
| 50 | $168Qa | $1.12Qi |
| 100 | $182Qi | $1.22Sx |
Income Scaling
Income scales linearly with copies owned — no diminishing returns, ever. Owning more of the Sushi Restaurant always earns proportionally more:
| Copies owned | Income per second |
|---|---|
| 1 | $219M/s |
| 10 | $2.19B/s |
| 25 | $5.48B/s |
| 50 | $11.0B/s |
| 100 | $21.9B/s |
Profit Calculations
| Payback period (1st copy) | 709,076 seconds |
| Income per dollar spent | $0.0/s per $1 |
| Efficient switch point | Around copy #4 (when the next copy costs more than Steakhouse) |
See the Business Tier List for how this business ranks against all other 99 tiers by payback period.
Unlock Requirements
There is no gating system on businesses in Tycoon Cards — the Sushi Restaurant is available to purchase from the very start of any run, the moment you can afford its $155T base cost. The only realistic "requirement" is reaching that amount of money, either by clicking, by owning cheaper businesses, or by carrying prestige and card bonuses from a previous run.
Best Upgrades
Individual businesses don't have their own upgrade trees in Tycoon Cards — the Sushi Restaurant always earns exactly $219M per copy at base rate. What actually "upgrades" its value are the game's shared systems: levelling supporting cards (below), earning achievement bonuses, and increasing your prestige multiplier. Each of these applies as a percentage on top of every business you own, including this one.
Best Supporting Cards
At this tier, cost-reduction cards give the best return — you'll buy many copies of this business, so every percentage off compounds across dozens of purchases. All-income cards are a strong secondary pick.
Prestige Recommendations
Expect to reach this tier within the first few minutes of any post-prestige run, especially once your card collection has a few levelled cost-reduction or all-income bonuses in place.

Research Interactions
Tycoon Cards does not currently include a research-tree system — the Sushi Restaurant cannot be researched or unlocked through any mechanic beyond simply affording it. A research tree is listed as a possible future system on our Updates & Roadmap page; this section will be updated if that ever changes.

Best Strategies
- This is a strong bridge tier — keep buying it until the cost of the next copy noticeably exceeds the base cost of the following tier, then switch.
- Combine with early cost-reduction cards for a noticeably faster ramp into the mid-game.
- Remember that all businesses share the same 15%-per-copy cost curve, so the fundamental buy/hold maths never changes — only the absolute numbers do.
