Where can I book a hotel to travel to Japan?

Tokyo is a land of gold, the hotel price is quite high and the room area is very small. I think it's quite expensive to book it myself. You can look at tour groups or free travel products. After all, big travel agencies have preferential prices for these resources, and it is sometimes cost-effective to catch up with the preferential prices. Last time, I signed up for a popular tour group. Food and accommodation are good, the tour fee is also cost-effective, and there are two or three days of free activities. Generally speaking, it's much cheaper than booking a hotel ticket myself.
