Restaurant in 小山町, Japan
Highway Curry Counter

A reliable highway chain stop inside EXPASA Ashigara on the Tomei Expressway, not a destination restaurant. CoCo Ichibanya delivers consistent, customisable Japanese curry with no booking required and visual menus that work for international travellers. Best visited on a weekday before noon. For destination dining in Japan, look elsewhere.
If you've eaten at CoCo Ichibanya before, you already know the format: customisable Japanese curry, ordered by spice level and topping combination, served fast and without fuss. The question on a return visit isn't whether the food will surprise you — it won't — but whether this particular location, inside the EXPASA Ashigara service area on the Tomei Expressway (downbound), is worth building a stop around. The short answer is yes, if you're already driving through Oyama-cho and need a reliable, filling meal without the uncertainty of walking into an unknown local restaurant.
CoCo Ichibanya's appeal is its consistency. The menu is the same nationwide, which means returning visitors can skip the deliberation and go straight to what works for them. For those who've been once, the move is to push one spice level higher than your last order, or add a topping you skipped previously , the chain's build-your-own structure rewards repeat visits more than single ones. The daytime experience here, given the service area context, runs smoother than evenings: highway traffic volumes mean the lunch window tends to be busier midweek, while weekends bring coach and tourist traffic that can create short queues at peak times. If timing is flexible, arriving before noon or after 2 PM on a weekday gives you the quickest turnover.
For a highway service area, the lunch vs. dinner distinction matters more than it would at a standalone restaurant. During lunch hours, the kitchen is at full operational pace, staff turnover is fast, and the curry arrives hot and freshly ladled. Evening visits, particularly on holiday weekends when Tomei traffic backs up, can mean a slower kitchen and a noisier, more crowded dining room. Daytime is the better call here, both for speed and atmosphere. If you're southbound toward the Izu Peninsula or Shizuoka in the morning, this is a practical first stop.
This is a walk-in venue with no reservation required or possible , booking difficulty is effectively zero. It sits inside the EXPASA Ashigara service area, which also offers other dining and retail options, so it competes for your attention with the wider service area offer. CoCo Ichibanya wins on portion reliability and the ability to eat exactly what you want without language-barrier risk: the menu has visual ordering systems that make it accessible for international travellers. Price range for the chain is generally accessible (most combinations fall under ¥1,500), though exact current pricing should be confirmed on arrival. For solo diners, this format is close to ideal: counter or table seating, no social pressure, and a meal you can finish in 20 minutes if you're pushing a schedule.
Comparing CoCo Ichibanya to the fine-dining venues associated with Japan's broader restaurant scene puts it in an entirely different category. If you're researching where to eat in Shizuoka Prefecture at a higher tier, our full Oyama-cho restaurants guide covers the wider options. For day-trip planning around the area, see also our Oyama-cho hotels guide, bars guide, and experiences guide. If you're travelling through Japan more broadly, venues like Goh in Fukuoka, Gion Sasaki in Kyoto, or Harutaka in Tokyo represent the kind of destination dining that requires advance planning and budget. CoCo Ichibanya here is not that. It is a dependable highway stop that does its job well.
