About this place
Umadoiwa is a rock face rising directly from the Oirase Gorge in Towada City, Aomori. It is a roadside viewpoint rather than a facility — there is no building, no ticket and no gate.
Because there is nothing built here, there is nothing for a navigation unit to snap to, which is exactly the case a mapcode handles well. There is no parking at the rock itself; use the Ishigedo Rest House lot upstream and walk the gorge path down to it.
Need a mapcode for somewhere else?
This site covers 30 places. Your hotel, the rental return lot, the restaurant you booked — those need mapcodes too, and they are not on this list. The app converts any Japanese address or place name, in English, Korean, Chinese or Japanese. Free.
How to enter this in your car navigation
- On the navigation home screen, choose Destination (目的地).
- Choose Mapcode (マップコード) from the search methods.
- Type the digits, then the asterisk and the last two digits.
- Confirm the map preview shows the right area before you set the route.
Most Japanese rental cars (Toyota, Nissan, Honda, Times, Orix) accept mapcodes. Some older units ignore the *nn suffix — that is fine, it only refines the pin.
Where these coordinates come from
A Japanese user searching for this by name was routed to a floodgate in Akishima, Tokyo — a completely different place that happens to share characters. The coordinates on this page were cross-checked against co-Trip and verified to fall upstream of Ishigedo, in the correct order along the gorge.

Frequently asked questions
- What is the mapcode for Umadoiwa?
- The mapcode is 612 702 537*71, pointing at a spot in 青森県. Written as decimal degrees the same point is 40.532477, 140.979200. A navigation unit takes the mapcode in far fewer keystrokes than the coordinates, so enter the code.
- What is a mapcode?
- A mapcode is a short numeric code that identifies a spot in Japan, developed by Denso. Japanese car navigation systems accept it directly, which avoids typing a Japanese address on a Japanese keyboard.
- How do I enter a mapcode in a Japanese rental car?
- On the navigation unit choose Destination (目的地), then Mapcode (マップコード), then type the digits. The two digits after the asterisk are an optional precision suffix; older units simply ignore them.
- What do the digits after the asterisk mean?
- They are a high-resolution suffix that narrows the point to roughly a few metres. Without them the code still resolves, just to a slightly wider area.
