For more efficient traffic handling, RJTT_APP covers the entire Tokyo Approach control area from GND-FL240 and mainly pre-sequences arriving traffic for the individual approach radar control units of Haneda and Narita airport. Transfer levels and traffic spacing shall be coordinated individually taking into consideration runway configuration and activity on nearby military TMAs.
Tokyo Departure serves both Haneda and Narita airports. If not agreed on differently with RJTG_E/W_CTR, departures shall be transferred climbing to FL200 if westbound and FL190 for north/east bound departures.

The table of units of measurement shown below is used within Japan FIR/UIR for air and ground operations.
| For measurement of: | Units used: |
|---|---|
| Distance used in navigation, position reporting, etc - generally in excess of 2 NM | Nautical Miles (NM) and tenths |
| Relatively short distances such as those relating to aerodromes (e.g., runway lengths) | Metres (m) |
| Altitudes, elevations and heights | Feet (ft) |
| Horizontal speed including wind speed | Knots (kt) |
| Vertical speed | Feet per minute (ft/min) |
| Wind direction for landing and taking off | Degrees Magnetic (°) |
| Wind direction except for landing and taking off | Degrees True (°) |
| Visibility, incl. runway visual range | Kilometres or metres (km or m) |
| Altimeter setting | Inch of mercury (inHg), Hectopascal (hPa) on request |
| Temperature | Degrees Celsius (°) |
| Weight | Metric Tonnes or Kilogrammes (t or kg) |
| Time | Hours (HR) and minutes (min); beginning at midnight UTC |
General
Except when operating as a special VFR flight, VFR flights shall be conducted so that the aircraft is flown in conditions of visibility and distance from clouds equal or greater than those specified in the table below.

| At or Above | Below | At or Above | Below | 300 m ( 1,000 ft) above the surface or below | ||
| Flight Visibility | 8,000 m | 5,000 m | 8,000 m | 1,500 m | 1,500 m* | |
