Isoyakitei is the casual restaurant right across the street from the ferry terminal in Oshidomari, the port town on the north side of Rishiri Island where the ferry from Wakkanai, on the Hokkaido mainland, comes in. I had a raw sea urchin bowl there at lunchtime in late June 2026. It had a gentle, clean saltiness, like a good broth, with no fishy smell at all. Here is what the bowl cost on the day, what else is on the menu, how busy it was and where to park.
How much is the sea urchin bowl at Isoyakitei?
I had the purple sea urchin bowl (nama-uni don, raw sea urchin on rice). It came with kelp, pickles and miso soup.
The printed menu on the table doesn't give a price for the sea urchin bowls, only "June to September". The day's prices were written on a whiteboard in the shop. On June 25, 2026 they were:
| Raw sea urchin bowl | Price on June 25, 2026 |
|---|---|
| Purple sea urchin | 7,000 yen |
| Purple sea urchin (small) | 5,500 yen |
| Bafun sea urchin | 15,000 yen |
| Mixed | 10,000 yen |
Bafun sea urchin (ezo bafun uni) is a smaller, short-spined kind. According to Rishiri Town, the fishing season is June to September for purple sea urchin and July to August for bafun sea urchin (Rishiri Town, as of November 2026), yet the whiteboard already listed a bafun price on June 25.
The taste was what stayed with me: a soft, clean saltiness like a good broth. Sea urchin is said to taste of what it eats, and Rishiri's grow up on Rishiri kombu and other seaweed, which is why there was no fishy smell.
If you are deciding between a bowl here and opening a sea urchin yourself on the west coast, I compare the two, with the season, here:

What else is on the menu: ramen, scallops and curry
Not everyone in your group has to eat sea urchin. The menu also has ramen, rice bowls and set meals, and all prices include tax (as of June 2026).
| Dish | Price |
|---|---|
| Original Rishiri ramen (ganso Rishiri ramen) | 1,950 yen |
| Ramen | 1,000 yen |
| Green onion and tororo kombu ramen | 1,600 yen |
| Raw scallop bowl (Rishiri scallops) | 3,700 yen |
| Scallop curry | 1,600 yen |
| Grilled fish set meal | 3,000 yen |
| Set menu (small ramen and small curry, and other combinations) | 1,700 yen |
Tororo kombu is Rishiri kelp shaved into fine, soft threads. The menu said the set menu is not served in the busy season.
Is there a wait at Isoyakitei?
I walked in alone at about 12:30 on June 25 and got a seat straight away; with a bigger group it may be different. The island's tourism site says it gets busy in the summer season, sometimes with a long line (Rishiri Plus, as of November 2026).
Going late has its own risk. When I stopped by at 14:00 the day before, the ramen had sold out and only the sea urchin bowls and a few other dishes were left. If you want ramen, go before the lunch rush is over.
Isoyakitei opening hours and parking
Isoyakitei is open April to October, 10:00 to 17:00, and the hours can change. There is no fixed closing day. The phone number is 0163-82-2561 (Rishiri Plus, as of November 2026). Closing at 17:00 makes it a lunch place, not a dinner one.
I parked at the ferry terminal parking lot. The lot, the terminal and Isoyakitei are all side by side, so it is only a short walk across.
The trailhead for Cape Peshi, the rocky hill beside the harbor with the best view on the island, is a 5 to 10 minute walk from the same lot. I climbed it first, then walked straight into Isoyakitei for lunch without moving the car.
