Dimensional Survey

A 'Window Café' Opens Off Haneda — A Place to Wait and Watch the Lit City, Lottery or No

A privately run café called Tomoshimado Sabo, or 'the Lit-Window Tea House,' opened on the 18th next to the observation rig for Stable Window 1, 'the Lit City,' off Haneda. As previously reported, the general viewing lottery can run more than twenty to one in some months; the café was conceived as a place for those who missed out, or families waiting their turn, to sit and watch the sea and the rig's lights instead of the window itself. The Dimensional Survey Division says it is the first private shop it has approved to use its published observation materials.

A privately run café called Tomoshimado Sabo — the Lit-Window Tea House — opened on the 18th at the foot of the observation rig for Stable Window 1, "the Lit City," off Haneda. As previously reported, the general viewing lottery for Window 1 draws applicants for just 80 slots a day, once a month, with odds running past twenty to one in busy months. While some, like Emiko Tadano, 58, previously reported to have finally won on her 104th attempt on Sept. 16, do get through, the vast majority go home having missed out. Tomoshimado Sabo was designed as a place for exactly those people.

Running the shop is Saku Miyai, 38, the fourth generation of a Haneda café that has served three generations of fishermen and rig staff before him. "This was always a place where fishermen and rig workers stopped by in the morning," he said. "I've watched families walk home disappointed after missing the lottery for years now. I wanted to make somewhere they could at least sit and watch the sea, and the rig's lights, while they wait."

The café's interior displays a selection of the Dimensional Survey Division's already-published observation materials — illustrations of the stone city and its lights — on its walls. The Division says this is the first time it has approved a private shop's commercial use of such materials, on condition that only already-published imagery is used, never the raw view through the window itself. "Given that demand for window merchandise already exists, we judged it better to draw a clear line and make it a healthy market than to let unauthorized, low-quality imitations spread unchecked," an official said.

Inside, seating faces not the window itself but the rig's lights and the night sea beyond the glass. The Lit City's window can't be seen from the shop at all. "What you can see from here is just the rig's lights. I think that's enough," Miyai said. "I didn't want to run a place for peeking at the other side."

On opening morning, the Division's briefing had listed Window 1 as "likely open, night." A sign by the door — reading either "Open today" or "Closed today," updated to match the day's forecast — has been trialed as part of the shop's setup. "I know it isn't guaranteed to open as forecast," Miyai said, "but it gives people a reason to come in with a little hope."

Among the opening-day customers was a mother, 34, who said she'd missed the lottery three times running, seated with her elementary-school-age son. "Even without getting to see it, just sitting here watching the rig's lights and wondering 'is it open today?' seems to satisfy him." Her son added, "If we can see the light, I wonder if they can see us too" — to which his mother laughed and replied, "Nobody knows that yet." The exchange echoed, almost word for word, the Division's long-standing position that there is no evidence the other side is aware of this one at all.

A corner of the shop also holds a small open shelf of materials on the ethics debate — clippings on the long openings previously reported at Windows 2, 4, and 5, and notes on the outside expert panel due to hold its first meeting within the year. "I didn't want to be a peeping shop, but I also didn't want to be a place that looked away from the question of whether we should be watching at all," Miyai said. A Division official commented, "Having that conversation reach a private space like this is, if anything, welcome."

The shop also sells postcards depicting the Lit City and replica versions of window drift objects, such as the previously reported tally tags. Genuine window drift objects fall under state ownership per the Dimensional Boundary Management Act and must pass through the Third Appraisal Center's window team, so none can be kept in the shop. "We don't have the real thing, and we shouldn't," Miyai said with a laugh. "We asked for the replicas to be made a little rougher on purpose, so no one mistakes them."

Emiko Tadano, 58, previously reported to have finally won the Window 1 viewing lottery on her 104th attempt on the night of Sept. 16, was also among the opening-day visitors. "The day I won I was too happy to sleep, but the actual viewing is still some time off," she said. "I thought I'd come here and wait until then." Miyai treated her to a coffee on the house to mark the opening. "Having spent more than a hundred draws on the losing side, it still makes me happy, even now that I've won, that a shop exists for the people who didn't," Tadano said with a laugh, and reportedly offered to leave behind a notebook of her own notes on weathering the lottery, for the next person who comes in.

The Dimensional Survey Division welcomed the café's opening as a private-sector initiative but was careful to add a caveat: "This is strictly something happening outside the rig. It doesn't substitute for the function or role of the window room itself." An official said, "We can't expect it to lower the lottery odds, but giving people who miss out one more way to spend the wait isn't a bad thing from our point of view either." As previously reported, the 80-slot daily cap on Window 1 viewings remains unchanged, so the café does nothing to ease the odds of the draw itself.

At the end of the opening-day interview, Miyai shared one more idea for the future: he said he's in talks with the Division about posting excerpts from window keepers' logs on the shop wall, within whatever limits are approved. "Not an 'answer' from the other side, but a place that introduces the words of the people working on this one," he said. As previously reported, individual window keepers are never named by the Division, but their log entries have been quoted in news coverage more than once, and Miyai said he hopes to build that everyday texture of "the people doing the watching" into one of the shop's pillars.

This reporter, watching how many customers simply sat gazing at the rig's lights rather than anything else, came away thinking the café's real invention may be a place to sit more calmly than the window room itself ever allows. Missing the lottery is nothing unusual in this city. Still, having somewhere for those who miss it to watch the sea and wait for the next draw counts, in its small way, as real good news for the Dimensional Survey page.

By evening on opening day, Miyai said, roughly 90 customers had come through — nearly three times what he'd expected. "We barely did any advertising to speak of. I think it spread by word of mouth, among people who'd missed the lottery telling each other," he said, not hiding his surprise. With only 18 seats, the shop expects waits to build by evening. "People might end up lining up," Miyai said, "but if they do, I think that's its own kind of waiting, one that fits this city."
