Hamtaro Sunflower Roulette (とっとこハム太郎ひまわりルーレット)
It is #4 in a children's medal series; #1 - Uminin Picture Matching, #2 - Uminin Fishing, and #3 Tottoko Hartarou Tottokomawaru Yo Hamu Chan Zu are found mentioned at the developer's site, all presumably published by Taito.
The developer's site is called t-sys.co.jp. It says they developed Ma Que Xuan Feng (which says it was developed by Sun Mixing) and Mahjong Gakuensai 2 (which only mentions the publisher Make Soft).
