No. Retail deposit rates are still above zero.
For example here's BoJ data (PDF)

Average interest rate on deposits : 0.001% (But think of how little tax you'll pay on the interest!).
There is a significant systemic risk to an economy from negative rates (apart from the obvious associated fact that if you need negative rates for stimulus then you're already in very deep trouble). The retail banking system is given further disincentive from holding cash reserves, they'll hold the bare minimum and unless prudential regulation is strictly enforced, they'll probably cheat on that as well. You could just trust them to do the right thing...
Yes.
"After five years of negative rates imposed by the European Central Bank, German lenders are breaking the last taboo: Charging retail clients for their savings starting with very first euro in the their accounts.
While many banks have been passing on negative rates to retail clients for some time, they have typically only done so for deposits of 100,000 euros ($111,000) or more. That is changing, with one small lender close to Munich planning to impose a rate of minus 0.5% to all savings in certain new accounts. Another bank in the east of the country has introduced a similar policy and a third is considering an even higher charge.
The lenders are preparing for a prolonged period of negative rates as Europe’s economy slows. In September, the European Central Bank reduced the deposit rate to minus 0.5% from minus 0.4%, making it more expensive for banks to park their excess cash there. While there are some exemptions under the policy, years of sub-par profitability have left especially smaller lenders with few options to offset the cost of the ECB’s charges.
“The floodgates are open,” said Friedrich Heinemann, who heads the department on Corporate Taxation and Public Finance at the ZEW economic research institute in Mannheim. “We will soon see a chain reaction. Banks that do not follow with negative interest rates would be flooded with liquidity.”
