This is a Japanese postmark with the date reading "2.7.24" and the location being Nikko (read from right to left). The time the postcard was accepted by the post office is indicated below the date.

As with Meiji Era Japanese postmarks (see the preceding page), the date is in the year-month-day format. This can't be Meiji 2 (1869, before the Japan Post Office was even established), so it must be Taisho 2 (1913) or Showa 2 (1927). My postage stamp catalog tells me that the postage stamp (Chrysanthemum series) was issued in 1899-1907, so it must be Taisho 2. This is confirmed by the English postmark elsewhere on the card.
