Downtown Pleasant Hill has spent close to a year waiting on a Japanese market that keeps missing its own opening date. In the meantime, a much smaller sushi restaurant nobody was tracking closely opened on schedule, took over a storefront near the movie theater, and started serving all-you-can-eat sushi in three price tiers before the bigger project even had a hiring sign posted. If you have been holding off on a downtown sushi night because you assumed the real action was still months away, the timeline says otherwise.
The Sushi Spot That Beat the Market to the Punch
Mizu Sushi Bar & Grill opened this spring at 2375 Contra Costa Blvd, Suite A, taking over the former Nama K-Street Food space near the movie theater in Downtown Pleasant Hill. The restaurant is part of a small California chain that has operated in Silicon Valley since 2008, with other locations in San Jose, Mountain View and Tustin, so Pleasant Hill is not getting a one-off concept built from scratch. It is getting a format the company has already run for years.
The twist that sets it apart from Pleasant Hill's existing sushi options is the pricing structure. Mizu runs an all-you-can-eat model with three tiers: Silver at $29.99, Gold at $39.99 and Diamond at $59.99, with kids' pricing also available. That is a meaningfully different proposition than ordering a few rolls at a typical neighborhood sushi counter. It is built for groups, families, and anyone who wants to work through a long list of nigiri, rolls and appetizers without doing the math on a per-piece bill.
Pleasant Hill already had sushi before Mizu arrived. What changed is the occasion. A quick lunch roll and a three-tier AYCE dinner are not the same errand, and downtown now has both within the same six blocks.
A Year of Moving Targets at 155 Crescent Plaza
The bigger story, and the one that actually explains why "Japanese food" has felt like a theme downtown this year, is happening a few blocks away at 155 Crescent Plaza. That address is the former Orchard Supply Hardware box, a 42,000 square foot building that has sat empty since the hardware chain closed. It is being converted into Osaka Marketplace, a Japanese grocery and food hall concept the company describes as a "grocerant," a full grocery floor combined with a semi-outdoor market hall built into the old garden center.
The plan calls for mini restaurants inside that market hall serving sushi, ramen, chicken karaage and bento boxes, alongside a grocery section stocked with fresh produce, seafood and imported goods. Osaka Marketplace already runs a similar format at its Fremont store, which pairs the grocery floor with a cafe and food court, so Pleasant Hill's version has a working blueprint rather than an unproven idea.
What it does not have, a year after it was first announced, is a firm opening date. Press materials that circulated when the deal was announced pointed to a November 2025 opening. A city update not long after revised that to "mid-2026." As of a report from mid-September 2026, the company has begun actively recruiting for the Pleasant Hill location, with job postings open across "all positions" and "all departments," but still no confirmed opening day. That puts the project closing in on a full year past its original target, with hiring underway and the calendar still open-ended.
Here is how the two projects compare on what is actually known right now:
| Mizu Sushi Bar & Grill | Osaka Marketplace | |
|---|---|---|
| Address | 2375 Contra Costa Blvd, Suite A | 155 Crescent Plaza (former Orchard Supply Hardware) |
| Status | Open since spring 2026 | Hiring as of September 2026, no confirmed opening date |
| Format | Sit-down AYCE sushi and grill, three price tiers | Grocery store plus semi-outdoor market hall with mini restaurants |
| Size | Single storefront | 42,000 square feet |
| What you get | Nigiri, rolls, teriyaki, Korean BBQ, skewers | Sushi, ramen, karaage, bento, plus full Japanese grocery |
Two Different Reasons to Walk Into the Same Six Blocks
The instinct is to lump these together as one Japanese food trend hitting downtown at once. That is not quite what is happening. Mizu is a destination meal, the kind of place you plan a Friday night around because you want to sit down and work through a tiered menu with a group. Osaka Marketplace, once it opens, is built for a completely different habit: the grocery run where you also pick up ready-to-eat ramen on the way out, or the errand where you grab bento for a weeknight dinner without cooking.
That distinction matters because it fits a pattern downtown has been running for a while, not a sudden shift. Osaka Marketplace is joining a list of recent tenants that includes Paris Baguette, Morgan Territory Brewing, Batter N' Icing, Cantina Jack's, Crumbs Breakfast & Lunch Bar and The Royale. None of those openings were part of a themed rollout. They landed in the same shopping center over roughly the same stretch of time because Downtown Pleasant Hill has been actively working to fill its storefronts, and Osaka Marketplace happens to be the largest and slowest-moving piece of that effort.
The Downtown Pleasant Hill Night Market adds another layer worth knowing about if you have not been paying attention to it. It returns on the first and third Friday of each month through November 20, 2026, with food, music and vendor booths. It is not tied to either restaurant, but it is one more reason the same stretch of Crescent Plaza is worth checking on a Friday night regardless of what is or is not open at 155.
What This Looks Like on an Actual Tuesday
If you live in the neighborhood, here is what the current lineup actually changes about a normal week:
- A weeknight AYCE dinner at Mizu is already an option, no waiting required, and the three-tier pricing means you can scale the meal to whoever is coming.
- The old OSH building is still under construction, so treat any specific Osaka Marketplace opening date you see online as unconfirmed until the company posts one itself.
- The first and third Friday Night Markets run through November 20, giving you a reliable evening out at Crescent Plaza that has nothing to do with either sushi spot.
- Once Osaka Marketplace does open, expect it to function more like a specialty grocery stop with food attached than a sit-down restaurant, which is a different trip than Mizu.
What the Delay Actually Tells You
The lesson here is not that Osaka Marketplace is in trouble or that downtown's food scene is stalling. Anchor projects of this size almost always take longer than the press release promised, especially when a company is converting a big-box shell into a custom build with a semi-outdoor market hall. Smaller independent openings like Mizu do not carry that same construction load, which is exactly why one arrived on schedule while the other kept moving its own deadline.
If you have been waiting for the big project to finish before treating downtown Pleasant Hill's Japanese food scene as real, the smaller restaurant already made that case for you. The larger one will get there. It just has not yet, and there is no reason to plan your week around a date nobody has confirmed.
