Product description ※Please note that product information is not in full comprehensive meaning because of the machine translation.

Summer vacation in 1975.
As a third year elementary school student, I was taken to the home of my uncle who runs a pottery shop in the northern Kanto region.
The strong sun of August and the rising thunderclouds, the voices of cicadas filling the hills and fields, the whispers of insects at night, the murmuring of the brook, and the meeting and parting.
The summer vacation that shines like a jewel will begin.
The PS version of Boku-no Natsuyasumi has been boldly revamped with new elements.
The number of insects that can be collected is twice that of the PS version. The insect sumo has been extensively revamped. You can also present or exchange "favorite" insects for your friends by using ad-hoc communications.
The scenarios are thicker and new Mr. Character appears, which you could not meet in the PS version.
