Lessons (8)
- The three gateways of tax — income, consumption, and assetsTaxes are classified in two ways: by who imposes them and by the phase in which they are collected. The phases are income, consumption, and assets.
- How Pensions Work — The Pay-As-You-Go and Funded SystemsJapan's public pension system is primarily based on the pay-as-you-go model. Premiums paid go to current recipients, not into your own account.
- Insurance Premiums in Practice — The Rate and Amount You PayLook not only at the rate, but also at the denominator and the cap. Japan applies 18.3 percent to standard remuneration; the US applies 12.4 percent to earnings up to a cap.
- Starting Age — Early and Deferred CollectionThe starting age determines the lifelong rate. In Japan, it's a 0.7 percent increase or 0.4 percent decrease per month.
- Medical and Long-Term Care Costs — The Percentage Paid at the Point of ServiceThe co-payment percentage is determined by age and income, and there is a monthly cap. Long-term care premiums are paid from age forty, with a 10% co-payment as a general rule.
- Public Finance and Government Bonds — A Quarter of Expenditures is DebtOf the 122.3 trillion yen in expenditure, social security accounts for one-third and national debt service for one-quarter. One-quarter of revenue is new borrowing.
- How Exchange Rates Affect Daily Life — Strong Yen and Weak YenA strong yen means one yen can buy more dollars. The exchange rate is set by supply and demand, affecting household finances through import prices and the following year's pension revision.
- Pensions and Prices — Nominal Amounts and Real ValueThe estimated amount on the statement is nominal. If the revision rate is lower than the inflation rate, purchasing power decreases. The Macroeconomic Slide does not lower the nominal amount.
