I'm not sure if this was really made at the Japan Mint, but I was told it was.

commemorative medal.
Japanese Mint medal with original cardboard circular case.

The obverse has a map of Hokkaido. Also, Imperial mums and
Ho-o bird, and an Army star.

Rebuilding Commemorative Medal, Showa 10
Yushima is a very famous Confucian temple. See
the Wikipedia link above.

The reverse has a mythical beast and what
appears to be a religious chant.
1929 Emperor's Visit to Osaka Commemorative.
Hallmarked 'Silver, Made at the Japanese Mint' on the edge.
The design has two imperial Ho-o birds. On the reverse is a Japanese shrine with the Emperor Enthronement banners outside.

Inscribed 'Silver Prize, Emperor Enthronement Commemorative, Osaka Exhibition, Taisho 4 [1915].'
Made by the Japan Mint; hallmarked on the edge of the medal
and in the case interior.
The artist's signature also has a date--1972--but I am not sure
this is the date when the medal itself was minted.
Fairly large. The medal itself measures about 7 cm diameter.
Very large and heavy piece from the Japanese Mint. I have seen similar pieces from the modern era,
not sure.

Osaka Mainichi Newspaper bronze medal.
Hallmarked by the Japanese Mint, but the case
(which is original to this piece) is hallmarked
by Shobido. Perhaps commissioned by the
latter to the former?
The inscription reads 'Osaka [?????] Elementary
School. Showa 8 [1933].'
The reverse says 'Graduation Commemorative' as well
as what appears to be the school charter.
