Boku no Natsuyasumi 3: Hokkoku Hen - Chiisana Boku no Dai Sougen ("My Summer Vacation 3: The Northern Chapter - Little Boku's Big Prairie") is the third entry in the My Summer Vacation series of nostalgia-based adventure games created by Kaz Ayabe at Millennium Kitchen. The title stars a young boy named Boku on his family trip to Hokkaido, Japan where he spends his summer vacation with his aunt and uncle during the month of August in 1975. Sony Interactive published Boku no Natsuyasumi 3 in Japan for the PlayStation 3 on July 5, 2007, making it one of the earlier games released for the system and the only entry in the Summer Vacation series to be released on HD hardware.
- Kaz Ayabe was born and raised in Hokkaido, Japan so Boku no Natsuyasumi 3 is heavily based off his memories of growing up in the region and is meant to be a love letter to his hometown.
- Hokkaido is known for its cool climate so when Kaz Ayabe first began thinking of setting a game in the region he thought of making the title about winter vacation. However, even though the final game took place in the summer, Ayabe still constructed the game's locations with the idea of returning to the setting for a winter-themed sequel. The theoretical sequel would star Boku's female cousin, Midori, and would most likely be called: Watashi no Fuyuyasumi (which translates to "My Winter Vacation" with the "watashi" being the causal version of the pronoun "my" often used by young women). In fact Kaz Ayabe was originally intending to make My Winter Vacation as his entry to Level-5's Guild anthology series but later reconsidered after he heard that Level-5's president was looking for more outlandish concepts, eventually leading to the creation of Attack of the Friday Monsters.
