Onuma Park, Hokkaido: 1937 (Apr. 28) to California, Cacheted with an all-over design showing a bridge across a river, with Mt. Koma in the distance (see the Komagatake Volcano cover below, with its Scenic Datestamp portraying the mountain), and franked with 6s postage to meet the unsealed letter rate. The four stamps are tied by two strikes of the Sapporo Scenic Datestamp, with blue "To US" handstamp alongside. Reverse shows only the combination notation "C-27 new". A lovely and fresh cover—and a one-of-a-kind., Very Fine.

Komagatake Volcano, Hokkaido: 1937 (Jan 22) to Connecticut, A generic hut-with-birds cachet, made site-specific by the addition of Mt. Koma in the distance. Franked by two Wedded Rocks flanking a 7s Tazawa, all three stamps tied by two outstanding strikes of a 12.1.22-dated Onuma Scenic Datestamp. Blue "To US" handstamp at left below inscription. Reverse bears "C-24." typed combination notation, a blue ") N (" handstamped opening remarque, plus a blue vertical oval kan handstamp across the flap. A remarkably clean cover, and the only one recorded., Very Fine.

Sapporo, Hokkaido: 1937 (Apr. 25) to California, Bearing the same cachet as the Onuma Park cover above, but showing slight design differences (including a Komagatake that nearly pops off the envelope). The eye-catching four-color franking totaling 6s is tied by two strikes of the Matsushima Kaigan Scenic Datestamp (located not in Hokkaido, but in Miyagi Prefecture on Honshu!). Blue "To US" handstamp at right, with the sole marking on the reverse being the combination "C-26 new". Sent unsealed. The only recorded cover from Sapporo—so bid high and raise a glass when you win! Very Fine.
