Commission when buying a second hand house in Tokyo / Osaka

Hi all,

I have read the legal maximum a real estate agent can charge for selling one a house is , 3% +60K.

However, how much have people be quoted or have paid when they have bought their second hand house in Tokyo or Osaka.

For example, for a 100,000,000jpy house, I have been quoted 3%, but I will be given a 30% discount if I conduct the transaction on weekdays, which effectively is 2% of the house price.

What have you guys been quoted / paid, when buying your house?

Thank you,
