Regarding 1P 20A circuit breaker per JIS standard, the maximum short-circuit current rating is

5KA. Consequently, it does not meet full rated system in panel schedule as described on each drawing of Electrical Panel Schedules.

This is inconsistent with the specification and drawings.

In this case, should we use the UL and NEMA standards so that US products can also be considered?

For JIS standard panels no 1P20A breakers are called for. Only 2P20A breakers, see panel shcedules on sheets 3B-E-701. Government shall provide Addendum for revised sheet PH-E-701 to show 2P20A breakers instead of 1P20A breakers. One-line on sheet PH-E-601 correctly shows
