Released by Key in 2018, the romance visual novel Summer Pockets is set on a small Seto Inland Sea island — and fans have traced much of it to the real island of Ogijima (女木島) near Takamatsu, Kagawa Prefecture. The Kamome (Seagull) route in particular features several locations that pilgrims can visit in real life.
This guide walks through each pilgrimage spot on Ogijima in detail, along with exactly how to reach them.
What Is Summer Pockets?
Summer Pockets is a 2018 romance visual novel by Key. The story follows a protagonist who spends a summer on the island where his late grandmother once lived, sorting through her belongings while building bonds with the friends he meets there. Its setting draws heavily on the atmosphere of the Seto Inland Sea islands, and Ogijima’s real landscapes became the model for much of the game’s world — drawing fans to retrace the story on location.

A Spot-by-Spot Guide to the Pilgrimage Sites
Ogijima’s pilgrimage locations cluster around the Onigashima Great Cave. Here’s each one, in the order you’ll naturally encounter them.
1. Onigashima Great Cave (the abandoned mine model)

The centerpiece of the pilgrimage is the Onigashima Great Cave itself — the real-world model for the abandoned mine cave that appears in the Kamome route. Fans often note how closely the cave’s rock walls and passageways echo the game’s background art. Since the cave is walkable inside, it’s worth taking your time as you move through it and picture the scenes it inspired.
Getting there
A local bus runs from Ogijima Port to the cave, taking about 20 minutes.
| Item | Details |
|---|---|
| Departure point | Ogijima Port |
| Transport | Bus |
| Travel time | About 20 minutes |
| Adult admission | ¥600 |

2. The mountain path around the cave (the secret-base route)
The mountain path surrounding the cave is a pilgrimage spot in its own right — it’s the model for the scenes where the characters make their way to their secret base. It’s easy to focus only on reaching the cave and walk right past this stretch, so take a moment to look around as you go; the path itself carries a lot of the game’s atmosphere.
3. The life-size Kamome panel (next to the ticket counter)

Right beside the cave’s ticket counter stands a life-size panel of Kamome — a photo op fans won’t want to skip. You can stop by either before or after your cave visit, which makes it an easy addition to your pilgrimage photo list.
4. The mine entrance vs. exit (a detail worth knowing)

Here’s a detail that trips up a lot of visitors: the mine entrance depicted in the game isn’t modeled on the cave’s main entrance — it’s modeled on the rear exit. Since the cave has more than one opening, it’s easy to mix the two up. Knowing this ahead of time makes for a much smoother visit.
Summary
Ogijima is dense with locations tied to the Kamome route of Summer Pockets. Centered on the Onigashima Great Cave — the model for the abandoned mine — the island’s pilgrimage spots include the cave interior, the surrounding mountain path, the life-size panel by the ticket counter, and the cave’s rear exit. Take your time exploring so you don’t walk past any of them.
