If you are looking up Mangwon Hatsu Kohi hours, the key point is simple but worth checking carefully: the cafe is most consistently listed as operating from 12:00 to 20:00, with Thursday shown as a regular closing day across several sources. Some listings differ on whether Friday is also closed, so the safest plan is to confirm before you go, especially if you are planning a Friday visit to Hatsu Kohi Mangwon.12
Hatsu Kohi is described as a cafe and dessert spot in Seongsan-dong, Mapo-gu, Seoul, with multiple listings giving the address as 32 Seongmisan-ro 1-gil. DiningCode identifies it as a Seongsan-dong cafe and dessert place, while other sources connect it naturally to the Mangwon cafe area.234
Mangwon Hatsu Kohi Hours at a Glance

The most repeated operating time for Hatsu Kohi is 12:00 to 20:00. Tableling lists the cafe as open Monday, Tuesday, Wednesday, Friday, Saturday, and Sunday from 12:00 to 20:00, with Thursday as the weekly regular closing day and no break time shown.2 DiningCode also shows 12:00 to 20:00 in its business information, along with the phone number 010-8213-2875.3
A 2025 review mirrored on Keyzard gives the same daily hours, 12:00 to 20:00, and states that the cafe is regularly closed every Thursday. It also describes the cafe as a small independent cafe near Mangwon Station, located about an eight-minute walk from Exit 1.4 Bbang Morning’s June 9, 2025 post, which introduced five vintage-style cafes in Mangwon-dong, also listed Hatsu Kohi with the official account @hatsu_kohi, the address 32 Seongmisan-ro 1-gil, and hours written as Friday through Wednesday, 12:00 to 20:00.5
There is one important wrinkle. The Wandeokhan Haru store page lists Hatsu Kohi’s hours as Monday, Tuesday, Wednesday, Saturday, and Sunday from 12:00 to 20:00, while marking both Thursday and Friday as regular closing days. The same page advises checking Instagram for holiday or closure confirmation.1 Because Tableling, Keyzard, and Bbang Morning indicate Thursday as the regular closure while Wandeokhan Haru includes Friday as closed too, Friday is the day that deserves the most extra caution.
Why the Thursday and Friday Detail Matters
For a casual cafe plan, 12:00 to 20:00 is a comfortable window. It works for a slow afternoon coffee, a dessert stop after walking around Mangwon, or an early evening break. But small cafes can be more sensitive to schedule changes than larger chains, and the source material here points to exactly that kind of caution.
The strongest shared pattern is that Hatsu Kohi opens at noon and closes at 8 p.m. The other strong pattern is that Thursday is a regular closing day. Tableling explicitly lists Thursday as the weekly regular holiday and says there is no break time, which is useful if you are trying to avoid arriving during a mid-afternoon pause.2 The Keyzard review also gives Thursday as the regular closing day, and Bbang Morning’s “Friday through Wednesday” wording implies the same Thursday closure.45
Friday is less clear. One source says Friday is open, while another says Friday is a regular closing day. Since the Wandeokhan Haru page also says to check Instagram for closure confirmation, the most practical reading is this: treat Thursday as the regular day off, and treat Friday as a day to verify before heading over.1 This is not a sign that the cafe is hard to visit; it simply means that the most reader-friendly advice is to avoid relying on a single listing when schedules disagree.
Location, Contact, and What Sources Say About the Cafe
Most source records place Hatsu Kohi at 32 Seongmisan-ro 1-gil, Mapo-gu, Seoul. Tableling lists it at that address, DiningCode gives the same road-name address, and the 2025 Keyzard review also identifies the cafe at 32 Seongmisan-ro 1-gil.234 The Wandeokhan Haru listing gives the location as Seongsan-dong 254-30, Mapo-gu, Seoul, which appears to refer to the same local area through a lot-number style address.1
If you need to contact the cafe, two sources list the phone number as 010-8213-2875. Wandeokhan Haru provides that contact number, and DiningCode shows the same number in its business information.13 For travelers or visitors who do not regularly use Korean map apps, having both the road-name address and phone number can make it easier to check the listing in a navigation app.
The sources also give a little context for what kind of place Hatsu Kohi is, without needing to overstate it. DiningCode presents it as a cafe and dessert spot and lists menu items including Napolitan at 9,500 won, melon soda at 6,500 won, and cream soda at 6,500 won.3 The Keyzard-mirrored review describes it as a small private cafe with a central group table and a few additional tables, and notes that parking is not available.4
Hatsu Kohi has also appeared in local culture and cafe coverage beyond ordinary listing pages. Bbang Morning included it in a June 9, 2025 post about five vintage-style cafes in Mangwon-dong, while NON LABEL covered a past Kinfolk House magazine and Cafe Hatsu Kohi pop-up held from September 22 to 23, 2023, at 32 Seongmisan-ro 1-gil, during the 12:00 to 20:00 time window.56

For planning purposes, the best source-backed summary is this: Hatsu Kohi’s commonly listed hours are 12:00 to 20:00, Thursday is the clearest regular closing day, and Friday should be checked in advance because listings conflict. If your schedule is flexible, visiting on Monday, Tuesday, Wednesday, Saturday, or Sunday during the noon-to-8 p.m. window is the most straightforward reading of the available information.
