Going alone: the coach wins by a mile — $151 (≈¥23,600) per person with ticket and lunch, against $447 for a car all to yourself plus ¥800 (≈$5.1) at the gate. The train day costs about the same as the coach, for more freedom and more transfers.
Two of you: the coach wins — $151 (≈¥23,600) each all-in, against $223 each in the cheapest car plus ¥800 (≈$5.1) each at the gate.
Three of you — almost even: the cheapest car splits to $149 (≈¥23,200) each against the coach's $151, but the ¥800 (≈$5.1) gate ticket each tips the total back to the coach. Take the car anyway if hotel pickup and your own pace are worth a few dollars.
Four of you — the real crossing: the cheapest car is $109 (≈¥17,000) each plus ¥800 (≈$5.1) at the gate against the coach's $151 (≈¥23,600). The cars win from here on.
Five of you: any car beats everything — $89–109 (≈¥13,900–17,000) each plus ¥800 (≈$5.1) at the gate. One booking, one vehicle, no station transfers with five people.
Six of you: $74 (≈¥11,500) each plus ¥800 (≈$5.1) in a six-seater — half the coach fare. Only the up-to-6 cars fit: the $545 (≈¥85,000) most-reviewed tour seats five.
