Three weeks in China can cost
half of one week in Japan.
If you're choosing between East Asian destinations on price, the math is no longer subtle. Hotels are 30–60% cheaper. Taxis are nearly 7× cheaper than Tokyo. High-speed rail is faster per yuan than anywhere on earth.

How much more a Tokyo taxi costs per kilometer than a Didi ride in Shanghai.
Average price gap between a 4-star hotel in Tokyo and the equivalent in Beijing.
Beijing to Shanghai by high-speed rail — 1,318 km, faster than driving, cheaper than flying.
The honest caveats
China is bigger, so internal distances are longer — a "domestic flight" in China can be 3 hours, against 1 hour in Japan. Plan more travel time per stop. International flights into Tier-2 cities still route via Beijing or Shanghai for most carriers.
Japan has the better convenience-store food economy; Korea has the cheaper domestic flights to Jeju. China wins on hotels, taxis, sit-down meals, and HSR — which is most of what a 10-day trip looks like. For most travelers, the difference is hundreds to thousands of dollars.
