How a Japanese Entrepreneur Built an Online Sober Rental Platform Across Asia

Hanae Moriuchi remembers the exact apartment in Setagaya where she sat across from a prospective landlord, hands folded neatly in her lap, rehearsing an answer she had prepared for weeks. The question, when it came, was not about her income or her guarantor. It was whether she had ever had a problem with alcohol. She had been sober for nineteen months at that point, paying her rent on time, working as a project manager at a mid-sized logistics firm in Tokyo. The landlord said he would call her back. He never did.

In our recent conversation, Moriuchi traced that moment in 2019 as the seed for her venture, an online sober rental marketplace that now operates across Japan, Singapore, Taiwan, and South Korea. The platform connects people in recovery from alcohol and other dependencies with vetted landlords who understand the realities of sober living. Moriuchi founded it in late 2020, after two years of research and a string of rejections from traditional real estate platforms that saw recovery housing as a niche too risky to host.

Origins in a Tokyo Apartment

Moriuchi's own path to sobriety began in her late twenties, a period she describes as quietly chaotic. She held a responsible position at a logistics company, managed a small team, and attended client dinners four nights a week. Drinking was woven into the social fabric of her work, and she found herself unable to imagine closing a deal without the ritual of shared bottles. By the time she acknowledged the problem, she had already lost two jobs and moved twice.

Recovery, she says, was the easier part in some ways. Finding a landlord who would accept her as a tenant was the harder one. Japanese rental contracts typically require a guarantor, a key money deposit, and sometimes an interview with the property owner. Several landlords she approached asked directly about her drinking history after seeing a gap in her employment history. One, after a long pause, told her that she seemed like a hard worker but that he preferred tenants without complications.

The experience pushed her to look outward. She read about sober living communities in the United States, attended meetings of Alcoholics Anonymous across Tokyo and Osaka, and corresponded with recovery housing operators in Sydney and Melbourne. Many of the Australian operators she interviewed ran small shared homes with strict house rules, but few had moved their listings online in a structured way. That observation stuck with her.

What the Platform Actually Does

The marketplace Moriuchi built operates in several languages and covers four countries, with headquarters split between Tokyo and Singapore. Landlords list properties ranging from small studio apartments to shared houses, and tenants create accounts that include a sobriety verification step. That step, she emphasises, is voluntary and confidential. No medical records are exchanged. Instead, applicants confirm they are in a recovery programme and agree to a short code of conduct.

The platform's screening process mirrors what a careful landlord in Melbourne or Brisbane might already do informally. References from recovery sponsors are checked, and tenants agree to maintain certain standards such as no alcohol on the premises and quiet hours after ten in the evening. In return, they receive a stable home, a community of peers, and protection from the kind of discriminatory questioning that pushed Moriuchi out of the conventional rental market.

She has been deliberate about keeping the platform lean. There is no flashy app, and listings are managed through a simple interface that works on older smartphones. This was a conscious choice, she explains, because many of the people who need sober housing most are rebuilding their lives on constrained budgets. A complicated platform would exclude them.

Core features available to tenants on the platform include:

Expansion Across Asia

Growth has not followed a straight path. Moriuchi launched in Japan first, where the cultural sensitivity around addiction made marketing particularly difficult. Public service announcements about alcoholism are uncommon, and the word "sober" carries connotations that many Japanese tenants initially found clinical or even shameful. To soften this, the platform's Japanese branding leans on the concept of calm living rather than recovery, an adjustment Moriuchi made after extensive user testing in Kyoto and Fukuoka.

Singapore and Taiwan came next. Singapore presented an opportunity because the rental market is highly regulated but also highly transparent, with English-language contracts common in private housing. Moriuchi partnered with two recovery charities in Singapore and now lists around three hundred properties across the island. Taiwan has been more fragmented, with listings concentrated in Taipei and Kaohsiung. South Korea is the newest market, added only this year after a slow pilot in Seoul.

She has encountered friction in each market. In South Korea, for instance, the practice of jeonse, a large refundable deposit, makes sober housing arrangements complex because many tenants in recovery cannot raise the lump sum. The platform has adapted by offering jeonse alternatives through partner landlords who accept smaller deposits with a co-signer from a recovery programme.

The platform now serves roughly four thousand active tenants across its four markets. Average stay is seven months, which Moriuchi considers a success, since many tenants eventually transition to conventional housing once their financial position stabilises. Landlord retention sits around seventy per cent, which she describes as healthy for a young platform. The team is fourteen people, distributed across the four countries and working in four languages.

Lessons Borrowed from the Australian Market

Australia has been an unlikely reference point for Moriuchi's team. She spent several months studying how sober living homes operate in Sydney and Melbourne, partly through reading and partly through conversations with operators she met at recovery conferences. The Australian model, with its emphasis on shared houses and accountability meetings, has shaped how the platform approaches listings in cities like Singapore and Taipei.

Some of those lessons translate awkwardly. Sydney's rental market is famously tight, with vacancy rates in some inner suburbs below two per cent. Japanese and Taiwanese renters do not face the same squeeze, but the principles still apply. Moriuchi adapted the Australian idea of mandatory house meetings into a feature on the platform that allows tenants to schedule weekly check-ins, either in person or via video, depending on what their city allows.

She has also drawn inspiration from Australia's recovery culture more broadly. The country has a long tradition of twelve-step programmes, and the slang around sobriety, the casual reference to staying sober today, has become part of her own marketing language. The platform's English-language blog now uses Australian recovery idioms in places, partly because they feel warmer and partly because many of the platform's early English-speaking users were based in Melbourne or Perth.

Building a Network to Cross Borders

Running a cross-border business from Tokyo would be impossible, Moriuchi says, without a strong professional network. In the early days she often felt isolated, particularly because her work sat at the intersection of property, health, and technology, three industries that rarely overlap in Japanese business culture. Building that network took years of patient work.

She credits much of her early progress to the international community in Kyoto, where she attended a small gathering that opened doors to mentors she still relies on today. For a candid look at how those networks function in practice, Building a professional network in Kyoto's international community offers a useful window. Moriuchi's own experience mirrors many of those patterns, with informal dinners and shared office spaces playing a larger role than formal associations.

Her advice for other founders in this space is straightforward. Find two or three recovery organisations in any new market and ask to volunteer. Attend their meetings. Offer to maintain their website or translate their materials. The trust you build in those first months will outlast any marketing budget.

A Practical Takeaway for Aspiring Founders

The sober rental space across Asia is still small, and most of the growth will come from operators willing to do patient work in markets where addiction is rarely discussed in public. Moriuchi's experience suggests three things for anyone considering a similar venture. First, the problem is real and consistent across cultures, even where it is hidden. Second, the existing rental industry is willing to engage if you bring structure rather than stigma. Third, the cultural translation of a sensitive product requires more time than the technology itself.

For founders working in recovery-adjacent fields, the lesson is to treat sobriety as a feature of the housing product, not a complication. When landlords see that recovery housing comes with lower turnover, more reliable rent, and a built-in support network, the conversation shifts quickly. Moriuchi has watched this happen repeatedly in Singapore and now, slowly, in Seoul. The market is finally starting to catch up with the people it has ignored for too long.
