Great Wave Cap - Black

神奈川沖浪裏 (Kanagawa-oki nami-ura): "under the wave off Kanagawa."

Katsushika Hokusai was about 70 when he published Under the Wave off Kanagawa, around 1831, as one sheet in his series Thirty-Six Views of Mount Fuji. Fuji is the series' subject, yet here it sits tiny in the trough while the wave curls over three boats of rowers. Much of that blue was Prussian blue, a pigment that had only recently reached Japan.

On the cap the wave stands alone on the front in royal blue and pale aqua, no boats and no mountain, just the clawed crest curling over. Under it, in small white katakana, is メガバイト (megabaito), "megabyte," a very modern word under a wave from 1831.

People with a Hokusai print on the wall will spot the wave first and the megabyte second. One size with a snap buckle makes it an easy gift, and the low profile stays close to the head. Faded Tokyo and Senpai styles sit beside it in the Japanese caps.
