Does Japan Airlines have an unconditional 24-hour refund policy?

I am trying to understand whether/when Japan Airlines has an unconditional 24-hour refund policy, i.e. offers a full ticket refund if the ticket was purchased through Japan Airlines in the last 24 hours, assuming one has completed the purchase one week or more before the original scheduled departure flight.

When testing the Japan Airlines website by booking a flight on https://www.jal.co.jp/jp/en/, it clearly states that tickets are non-refundable, with a few exceptions:

The exceptions are listed in the following link: Peace of mind travel with free reservation changes (mirror), which states:

If your travel is disrupted due to a JAL flight cancellation, schedule change, or entry restrictions, you may also rebook or refund your ticket free of charge.

This means there no unconditional 24-hour refund policy.

However, on https://www.jal.co.jp/arl/region/en/other/csplan.html (mirror), I do read that there is an unconditional 24-hour refund policy:

JAL is dedicated to provide refunds of tickets to our customers with minimal inconvenience. Reservations can be held at the quoted fare without payment, or refunded within twenty four (24) hours after the reservation if the reservation is made one (1) week or more before departure. After this twenty four (24) hour period, the refund amount will be calculated based on the fare rules of your tickets.

I don't know to which tickets this policy applies. All tickets purchased on Japan Airlines' official website? A subset of it (e.g., out/in from/to the US)? All tickets with Japan Airlines, including purchased via agencies? etc.

This confuses me. Do any tickets purchased on Japan Airlines' official website have an unconditional 24-hour refund policy? (assuming one has completed the purchase one week or more before the original scheduled departure flight)
