Airplane cup from a Kanto-gun unit.

Inscribed 'Kwantung Army Air Corps, Victorious Return Commemorative.'
Beautiful hand-painted fighter plane, clouds, and trees.
Inscribed 'Tachiarai, 4th Air Corps, Abe'. The red name is probably
that of the artist. It looks like the first kanji in 'Hattori'.

Tachiarai is in Fukuoka Prefecture. The IJA established an Air Base
(and the 4th regiment) there in 1919, In 1940 an Army Flight School
was opened. However, it was destroyed in 1945 by U.S. bombers.

I believe the 4th Regiment from Tachiarai was part of the Pearl
Harbor attack force.
This is a rare Navy fighter plane cup from the Kutani kiln.
Beautiful flower and swirls decoration around the rim on both the inside and outside.

Inscribed '
Houkokugou  [plane donated to the Navy], (North Country Gou), Plane Naming Ceremony Commemorative, Ministry of
the Navy'.

Planes donated to the Army were designated
Aikokugou, while the above phrase was reserved for planes donated to the Navy.
Citizen groups often pooled their money to buy planes and then there was an elaborate naming ceremony held. Between 1932
and 1945 there were around 1800 planes donated to the Navy. The phrase is parentheses above is probably the name given to
the plane. It is called
Hokkoku-gou in Japanese
